essay about causes and effects of immigration

Immigration: Causes and Effects

Introduction, economic causes, social causes, works cited.

For a long time, immigration has been a significant policy subject in the United States, with numerous reports and studies conducted on its motives and implications. Immigration is the movement or relocation of people from one country to another. Factors that promote immigration can be categorized to economic, social, and political causes. Although limited by slight economic downsides and political backlash, immigration is necessary for creating social diversity, protecting individuals’ rights and freedoms, and enhancing international relations. There are two significant groups of immigration causes: economic and social, which are associated with particular consequences.

First, the economic causes for immigration are high demand of manpower, unemployment, the desire for better entrepreneurial and employment opportunity. Income and economic status differences between resident and destination nations encourage people to migrate from poor to more prosperous countries. Developed countries have a high demand for labor unlike in less developed countries with high unemployment rates (Duan 3). The shortage of specialists in a particular profession in a specific region increases wages for this profession and stimulates the influx of migrants. The effect of the economic causes of immigration is overwhelming the available opportunities and resources. In 2019, the American Immigration Council reported a population of 44.9 million immigrants in the U.S (American Immigration Council 1). The right-wing Democratic Party in the US is opposed to immigration in effect, that unregulated inflow of foreign labor increases job competition, reduced wages, and increased unemployment. The social zeal for a better quality of life and connection to friends and families promoting immigration results in enhanced diversity, improved international relations, cross-cultural exchange, cosmopolitanism and diversity. Immigration has enhanced international relations and access to social amenities such as education.

The social rationale for immigration is aspirations for a better quality of life and connection with close family and friends. Social factors that influence the rate of immigration include crime rate, access to social amenities such as schools, and inter-cultural exchange (Duan 2). An immigrant can sponsor a family member or friend through an affidavit. Political grounds for immigration include state policies, threats of persecution, armed conflict, and humanitarian issues that force people to seek refuge in stable countries. The social causes of immigration are the inclination for a better life, while political migration is often due to unsafe conditions in the residence country. The effect of social immigration is in the occurrence of cosmopolitanism resulting from social immigration enhances the redistribution of wealth diversity and adequate co-existence of nationalities and socio-cultural exchange. Immigration protects the rights and freedoms of individuals advanced of their countries by political factors of armed conflict, state assassination, and discrimination.

Ultimately, immigration is a significant economic, social, and political factor with clashing implications. The desire for better quality of life and family bonds social causes of immigration lead to enhanced diversity, cosmopolitanism, cross-cultural exchange and international relations. Moreover, immigration protects the rights and freedoms of people threatened by political factors. On the downside the economic immigration driven by the desire for better employment and investment opportunities is characterized by high unemployment, prejudice, discrimination, and political backlash. While policymakers perceive immigration to drive slow wage growth and unemployment, Immigrants present remarkable social, economic, and political benefits. Therefore, migration significantly affects the economic and social structure of the countries. The mentioned effects are connected with the primary causes of migration.

International migration is a multifaceted process with distinct stages and decision points. An initial decision to leave one’s country of birth may be made by the individual or the family unit, and this decision may reflect a desire to reconnect with friends and family who have already moved abroad, a need to diversify the family’s access to financial capital, a demand to increase wages, or a belief that conditions abroad will provide social and/or political benefits not available in the homeland. Once the individual has decided to move abroad, the next decision is the choice of destination. Standard explanations of destination choice have focused on the physical costs associated with moving—moving shorter distances is often less expensive than moving to a destination farther away; these explanations have recently been modified to include other social, political, familial, and cultural dimensions as part of the transaction cost associated with migrating. Arrival in a host country does not mean that an émigré’s relationship with their homeland is over. Migrant networks are an engine of global economic integration—expatriates help expand trade and investment flows, they transmit skills and knowledge back to their homelands, and they remit financial and human capital. Aware of the value of their external populations, home countries have developed a range of policies that enable them to “harness” their diasporas.

Introduction

The steady growth of international labor migration is an important, yet underappreciated, aspect of globalization. 1 In 1970 , just 78 million people, or about 2.1% of the global population, lived outside their country of birth. By 1990 , that number had nearly doubled to more than 150 million people, or about 2.8% of the global population (United Nations Population Division, 2012 ). Despite the growth of populist political parties and restrictionist movements in key destination countries, the growth in global migration shows no signs of slowing down, with nearly 250 million people living outside their country of birth as of 2015 . While 34% of all global migrants live in industrialized countries (with the United States and Germany leading the way), 38% of all global migration occurs between developing countries (World Bank, 2016 ).

Identifying the causes and consequences of international labor migration is essential to our broader understanding of globalization. Scholars across diverse academic fields, including economics, political science, sociology, law, and demography, have attempted to explain why individuals voluntarily leave their homelands. The dominant thread in the labor migration literature is influenced by microeconomics, which posits that individuals contemplating migration are rational, utility-maximizing actors who carefully weigh the potential costs and benefits of leaving their country of origin (e.g., Borjas, 1989 ; Portes & Böröcz, 1989 ; Grogger & Hanson, 2011 ). The act of migration, from this perspective, is typically conceptualized as an investment from which a migrant expects to receive some benefit, whether it be in the form of increased income, political freedom, or enhanced social ties (Schultz, 1961 ; Sjaastad, 1962 ; Collier & Hoeffler, 2014 ).

In this article we go beyond the treatment of migration as a single decision and conceive of it as a multifaceted process with distinct stages and decision points. We identify factors that are relevant at different stages in the migration process and highlight how and when certain factors interact with others during the migration process. Economic factors such as the wage differential between origin and destination countries, for example, may be the driving factor behind someone’s initial decision to migrate (Borjas, 1989 ). But when choosing a specific destination, economic factors may be conditioned by political or social conditions in that destination (Fitzgerald, Leblang, & Teets, 2014 ). Each stage or decision point has distinguishing features that are important in determining how (potential) migrants respond to the driving forces identified by scholars.

This is certainly not a theoretical innovation; migration has long been conceived of as a multi-step process, and scholars often identify the stage or decision point to which their argument best applies. However, most interdisciplinary syntheses of the literature on international labor migration do not provide a systematic treatment of this defining feature, instead organizing theoretical and empirical contributions by field of study, unit or level of analysis, or theoretical tradition (e.g., Portes & Böröcz, 1989 ; Massey et al., 1993 ; European Asylum Support Office, 2016 ). Such approaches are undoubtedly valuable in their own right. Our decision to organize this discussion by stage allows us to understand this as a process, rather than as a set of discrete events. As a result, we conceptualize international labor migration as three stages or decision points: (a) the decision to migrate or to remain at home, (b) the choice of destination, and (c) the manner by which expatriates re-engage—or choose not to re-engage—with their country of origin once abroad. We also use these decision points to highlight a number of potential new directions for future research in this still-evolving field.

Figure 1. Global migration intentions by educational attainment, 2008–2017.

Should I Stay or Should I Go, Now?

The massive growth in international labor migration in the age of globalization is remarkable, but the fact remains that over 95% of the world’s population never leave their country of origin (United Nations Population Division, 2012 ). Figure 1 shows the percentage of people who expressed an intention to move abroad between 2008 and 2017 by educational attainment, according to data from the Gallup World Poll. Over this time period, it appears that those who were highly educated expressed intent to migrate in greater numbers than those who had less than a college education, although these two groups have converged in recent years. What is most striking, however, is that a vast majority of people, regardless of educational attainment, expressed no desire to move abroad. Even though absolute flows of migrants have grown at a near-exponential rate, relative to their non-migrating counterparts, they remain a small minority. What factors are important in determining who decides to migrate and who decides to remain at home? 2

From Neoclassical Economics to the Mobility Transition

Neoclassical economic models posit that the primary driving factor behind migration is the expected difference in wages (discounted future income streams) between origin and destination countries (Sjaastad, 1962 ; Borjas, 1989 ; Clark, Hatton, & Williamson, 2007 ). All else equal, when the wage gap, minus the costs associated with moving between origin and destination, is high, these models predict large flows of labor migrants. In equilibrium, as more individuals move from origin to destination countries, the wage differential narrows, which in turn leads to zero net migration (Lewis, 1954 ; Harris & Todaro, 1970 ). Traditional models predict a negative monotonic relationship between the wage gap and the number of migrants (e.g., Sjaastad, 1962 ). However, the predictions of neoclassical models are not well supported by the empirical record. Empirical evidence shows that, at least in a cross-section, the relationship between economic development and migration is more akin to an inverted U. For countries with low levels of per capita income, we observe little migration due to a liquidity constraint: at this end of the income distribution, individuals do not have sufficient resources to cover even minor costs associated with moving abroad. Increasing income helps to decrease this constraint, and consequently we observe increased levels of emigration as incomes rise (de Haas, 2007 ). This effect, however, is not monotonic: as countries reach middle-income status, declining wage differentials lead to flattening rates of emigration, and then decreasing rates as countries enter later stages of economic development. 3

Some research explains this curvilinear relationship by focusing on the interaction between emigration incentives and constraints : for example, increased income initially makes migration more affordable (reduces constraints), but also simultaneously reduces the relative economic benefits of migrating as the wage differential narrows (as potential migrants now have the financial capacity to enhance local amenities) (Dao, Docquier, Parsons, & Peri, 2016 ). The theoretical underpinnings of this interaction, however, are not without controversy. Clemens identifies several classes of theory that attempt to explain this curvilinear relationship—a relationship that has been referred to in the literature as the mobility transition (Clemens, 2014 ). These theories include: demographic changes resulting from development that also favor emigration up to a point (Easterlin, 1961 ; Tomaske, 1971 ), the loosening of credit restraints on would-be migrants (Vanderkamp, 1971 ; Hatton & Williamson, 1994 ), a breakdown of information barriers via the building of transnational social networks (Epstein, 2008 ), structural economic changes in the development process that result in worker dislocation (Zelinsky, 1971 ; Massey, 1988 ), the dynamics of economic inequality and relative deprivation (Stark, 1984 ; Stark & Yitzhaki, 1988 ; Stark & Taylor, 1991 ), and changing immigration policies in destination countries toward increasingly wealthy countries (Clemens, 2014 ). While each of these play some role in the mobility transition curve, Dao et al. ( 2016 ) run an empirical horse race between numerous explanations and find that changing skill composition resulting from economic development is the most substantively important driver. Economic development is correlated with an increase in a country’s level of education; an increase in the level of education, in turn, is correlated with increased emigration. However, traditional explanations involving microeconomic drivers such as income, credit constraints, and economic inequality remain important factors (Dao et al., 2016 ). The diversity of explanations offered for the mobility transition curve indicates that while most research agrees the inverted-U relationship is an accurate empirical portrayal of the relationship between development and migration, little theoretical agreement exists on what drives this relationship. Complicating this disagreement is the difficulty of empirically disentangling highly correlated factors such as income, skill composition, and demographic trends in order to identify robust causal relationships.

Political Conditions at the Origin

While there is a scholarly consensus around the mobility transition and the role of economic conditions, emerging research suggests that the political environment in the origin country may also be salient. We do not refer here to forced migration, such as in the case of those who leave because they are fleeing political persecution or violent conflict. Rather, we focus on political conditions in the homeland that influence a potential migrant’s decision to emigrate voluntarily. Interpretations of how, and the extent to which, political conditions in origin countries (independent of economic conditions) influence the decision to migrate have been heavily influenced by Hirschman’s “Exit, Voice, and Loyalty” framework (Hirschman, 1970 , 1978 ). Hirschman argues that the opportunity to exit—to exit a firm, an organization, or a country—places pressure on the local authorities; voting with one’s feet forces organizations to reassess their operations.

When applied to the politics of emigration, Hirschman’s framework generates two different hypotheses. On the one hand, politicians may allow, encourage, or force the emigration of groups that oppose the regime as a political safety valve of sorts. This provides the government with a mechanism with which to manage potential political challengers by encouraging their exit. On the other hand, politicians—especially those in autocracies—may actively work to prevent exit because they fear the emigration of economic elites, the highly skilled, and others who have resources vital to the survival of the regime. 4

A small number of studies investigate how local-level, rather than national, political circumstances affect a potential migrant’s calculus. The limited empirical evidence currently available suggests that local conditions are substantively important determinants of the emigration decision. When individuals are highly satisfied with local amenities such as their own standard of living, quality of public services, and overall sense of physical security, they express far less intention to migrate compared with highly dissatisfied individuals (Dustmann & Okatenko, 2014 ). Furthermore, availability of public transport and access to better education facilities decreases the propensity to express an intention to emigrate (Cazzuffi & Modrego, 2018 ). This relationship holds across all levels of wealth and economic development, and there is some evidence that satisfaction with local amenities matters as much as, or even more than, income or wealth (Dustmann & Okatenko, 2014 ).

Political corruption, on both national and local levels, also has substantively important effects on potential migrants, especially those who are highly skilled. Broadly defined as the use of public office for political gain, political corruption operates as both a direct and an indirect factor promoting emigration. 5 Firstly, corruption may have a direct effect on the desire to emigrate in that it can decrease the political and economic power of an individual, leading to a lower standard of living and poorer quality of life in origin countries. If the reduction in life satisfaction resulting from corruption is sufficiently high—either by itself or in combination with other “push” factors—then the exit option becomes more attractive (Cooray & Schneider, 2016 ). Secondly, corruption also operates through indirect channels that influence other push factors. Given the large literature on how political corruption influences a number of development outcomes, it is conceivable that corruption affects the decision-making process of a potential migrant through its negative effect on social spending, education, and public health (Mo, 2001 ; Mauro, 1998 ; Gupta, Davoodi, & Thigonson, 2001 ).

The combination of its direct and indirect impacts means that corruption could be a significant part of a migrant’s decision-making process. At present there is limited work exploring this question, and the research does not yield a consensus. Some scholars argue that political corruption has no substantive effect on total bilateral migration, but that it does encourage migration among the highly skilled (Dimant, Krieger, & Meierrieks, 2013 ). This is the case, the argument goes, because corruption causes the greatest relative harm to the utility of those who have invested in human capital, who migrate to escape the negative effect on their fixed investment. In contrast, others find that a high level of corruption does increase emigration at the aggregate level (Poprawe, 2015 ). More nuanced arguments take into account the intensity of corruption: low to moderate levels of corruption lead to increased emigration of all groups, and especially of the highly skilled. But at high levels of corruption, emigration begins to decrease, indicating that intense corruption can act as a mobility constraint (Cooray & Schneider, 2016 ). All of these existing accounts, however, employ state-level measures of corruption by non-governmental organizations, such as those produced by Transparency International. Scholars have yet to harness micro-level survey data to explore the influence of personal corruption perception on the individual’s decision-making process.

The Land of Hopes and Dreams

Given that an individual has decided to emigrate, the next decision point is to choose a destination country. Advanced industrial democracies, such as those in the OECD, are major migrant-receiving countries, but so are Russia and several Gulf countries including Saudi Arabia, Qatar, and the United Arab Emirates (World Bank, 2016 ). A country’s constellation of political, economic, and social attributes is crucial to understanding an emigrant’s choice of destination. Potential migrants weigh all of these factors simultaneously when choosing a destination: will the destination allow political rights for the migrant and their children, is access to the labor market possible, and does the destination provide an opportunity for reunification with friends and family? In this section we focus on the non-economic factors that draw migrants to certain countries over others. In addition, we emphasize how skill level adds layers of complexity to a migrant’s calculus.

Political Environment, Both Formal and Informal

As noted earlier, traditional neoclassical models and their extensions place wage differentials and associated economic variables at the heart of a migrant’s choice. Gravity models posit that migrants choose a destination country based on their expected income—which itself is a function of the wage rate and the probability of finding employment in the destination—less the costs associated with moving (Ravenstein, 1885 ; Todaro, 1969 ; Borjas, 1989 ). A rigid focus on economic factors, however, blinds us to the empirical reality that a destination country’s political environment influences what destination a migrant chooses (Borjas, 1989 ). A country’s legal and political rights structure for migrants, as well as its level of tolerance for newcomers, is critical to migrants discriminating between an array of potential destinations. Fitzgerald, Leblang, and Teets ( 2014 ) argue, for example, that states with restrictive citizenship policies and strong radical right anti-immigrant parties will receive fewer migrants, while states with relatively liberal citizenship requirements and weak radical right political movements will receive more migrants. In the rational actor framework, migrants seek countries with hospitable political environments to maximize both their political representation in government and their access to labor market opportunities as a result of citizenship rights and social acceptance (Fitzgerald et al., 2014 ).

Using a broad sample of origin countries and 18 destination countries, they find that relative restrictiveness of citizenship policies and level of domestic support for the radical right are substantively important determinants of global migratory flows. Further, they find that these political variables condition a migrant’s choice of destination: the relative importance of economic factors such as the unemployment rate or the wage differential diminishes as a destination country’s political environment becomes more open for migrants. In other words, when migrants are choosing a destination country, political considerations may trump economic ones—a finding that is an important amendment to the primarily economics-focused calculus of the initial stage of the immigration decision.

However, prior to choosing and entering a destination country, a migrant must also navigate a country’s immigration policy—the regulation of both migrant entry and the rights and status of current migrants. While it is often assumed that a relatively more restrictive immigration policy deters entry, and vice versa, a lack of quantitative data has limited the ability of scholars to confirm this intuition cross-nationally. Money ( 1999 ) emphasizes that the policy output of immigration politics does not necessarily correlate with the outcome of international migrant flows. There are a number of unanswered questions in this field, including: is immigration policy a meaningful determinant of global flows of migration? Do certain kinds of immigration policies matter more than others? How does immigration policy interact with other political and economic factors, such as unemployment and social networks?

Only a handful of studies analyze whether or not immigration policy is a significant determinant of the size and character of migratory flows. Perhaps the most prominent answer to this question is the “gap hypothesis,” which posits that immigration rates continue to increase despite increasingly restrictive immigration policies in advanced countries (Cornelius & Tsuda, 2004 ). Some subsequent work seems to grant support to the gap hypothesis, indicating that immigration policy may not be a relevant factor and that national sovereignty as it relates to dictating migrant inflows has eroded significantly (Sassen, 1996 ; Castles, 2004 ). The gap hypothesis is not without its critics, with other scholars arguing that the existing empirical evidence actually lends it little or no support (Messina, 2007 ).

A more recent body of literature does indicate that immigration policy matters. Brücker and Schröder ( 2011 ), for example, find that immigration policies built to attract highly skilled migrants lead to higher admittance rates. They also show that diffusion processes cause neighboring countries to implement similar policy measures. Ortega and Peri ( 2013 ), in contrast to the gap hypothesis literature, find that restrictive immigration policy indeed reduces migrant inflows. But immigration policy can also have unintended effects on international migration: when entry requirements increase, migrant inflows decrease, but migrant outflows also decrease (Czaika & de Haas, 2016 ). This indicates that restrictive immigration policy may also lead to reduced circular migrant flows and encourage long-term settlement in destination countries.

Disaggregating immigration policy into its different components provides a clearer picture of how immigration policy may matter, and whether certain components matter more than others. Immigration policy is composed of both external and internal regulations. External regulations refer to policies that control migrant entry, such as eligibility requirements for migrants and additional conditions of entry. Internal regulations refer to policies that apply to migrants who have already gained status in the country, such as the security of a migrant’s legal status and the rights they are afforded. Helbling and Leblang ( 2017 ), using a comprehensive data set of bilateral migrant flows and the Immigration Policies in Comparison (IMPIC) data set, find that, in general, external regulations prove slightly more important in understanding migrant inflows (Helbling, Bjerre, Römer, & Zobel, 2017 ). This indicates that potential migrants focus more on how to cross borders, and less on the security of their status and rights once they settle. They do find, however, that both external and internal components of immigration are substantively important to international migrant flows.

The effects of policy, however, cannot be understood in isolation from other drivers of migration. Firstly, poor economic conditions and restrictive immigration policy are mutually reinforcing: when the unemployment rate is elevated, restrictive policies are more effective in deterring migrant flows. An increase in policy effectiveness in poor economic conditions suggests that states care more about deterring immigration when the economy is performing poorly. Secondly, a destination country’s restrictive immigration policy is more effective when migrants come from origin countries that have a common colonial heritage. This suggests that cultural similarities and migrant networks help to spread information about the immigration policy environment in the destination country. Social networks prove to be crucial in determining how much migrants know about the immigration policies of destination countries, regardless of other cultural factors such as colonial heritage or common language (Helbling & Leblang, 2017 ). In summary, more recent work supports the idea that immigration policy of destination countries exerts a significant influence on both the size and character of international migration flows. Much work remains to be done in terms of understanding the nuances of specific immigration policy components, the effect of policy change over time, and through what mechanisms immigration policy operates.

Transnational Social Networks

None of this should be taken to suggest that only political and economic considerations matter when a potential migrant contemplates a potential destination; perhaps one of the biggest contributions to the study of bilateral migration is the role played by transnational social networks. Migrating is a risky undertaking, and to minimize that risk, migrants are more likely to move to destinations where they can “readily tap into networks of co-ethnics” (Fitzgerald et al., 2014 , p. 410). Dense networks of co-ethnics not only help provide information about economic opportunities, but also serve as a social safety net which, in turn, helps decrease the risks associated with migration, including, but not limited to, finding housing and integrating into a new community (Massey, 1988 ; Portes & Böröcz, 1989 ; Portes, 1995 ; Massey et al., 1993 ; Faist, 2000 ; Sassen, 1995 ; Light, Bernard, & Kim, 1999 ). Having a transnational network of family members is quite important to destination choice; if a destination country has an immigration policy that emphasizes family reunification, migrants can use their familial connections to gain economically valuable permanent resident or citizenship status more easily than in other countries (Massey et al., 1993 , p. 450; Helbing & Leblang, 2017 ). When the migrant is comparing potential destinations, countries in which that migrant has a strong social network will be heavily favored in a cost–benefit analysis.

Note, however, that even outside of a strict rational actor framework with perfect information, transnational social networks still may be quite salient to destination choice. An interesting alternative hypothesis for the patterns we observe draws on theories from financial market behavior which focus on herding. Migrants choosing a destination observe the decisions of their co-ethnics who previously migrated and assume that those decisions were based on a relevant set of information, such as job opportunities or social tolerance of migrants. New migrants then choose the same destination as their co-ethnics not based on actual exchanges of valuable information, but based solely on the assumption that previous migration decisions were based on rational calculation (Epstein & Gang, 2006 ; Epstein, 2008 ). This is a classic example of herding, and the existing empirical evidence on the importance of transnational social networks cannot invalidate this alternative hypothesis. One could also explain social network effects through the lens of cumulative causation or feedback loops: the initial existence of connections in destination countries makes the act of migration less risky and attracts additional co-ethnics. This further expands migrant networks in a destination, further decreasing risk for future waves of migrants, and so on (Massey, 1990 ; Fussel & Massey, 2004 ; Fussel, 2010 ).

No matter the pathway by which social networks operate, the empirical evidence indicates that they are one of the most important determinants of destination choice. Potential migrants from Mexico, for example, who are able to tap into existing networks in the United States face lower direct, opportunity, and psychological costs of international migration (Massey & Garcia España, 1987 ). This same relationship holds in the European context; a study of Bulgarian and Italian migrants indicates that those with “social capital” in a destination community are more likely to migrate and to choose that particular destination (Haug, 2008 ). Studies that are more broadly cross-national in nature also confirm the social network hypothesis across a range of contexts and time periods (e.g., Clark et al., 2007 ; Hatton & Williamson, 2011 ; Fitzgerald et al., 2014 ).

Despite the importance of social networks, it is, again, important to qualify their role in framing the choice of destinations. It seems that the existence of co-ethnics in destination countries most strongly influences emigration when they are relatively few in number. Clark et al. ( 2007 ), in their study of migration to the United States, find that the “friends and relatives effect” falls to zero once the migrant stock in the United States reaches 8.3% of the source-country population. In addition, social networks alone cannot explain destination choice because their explanatory power is context-dependent. For instance, restrictive immigration policies limiting legal migration channels and family reunification may dampen the effectiveness of networks (Böcker, 1994 ; Collyer, 2006 ). Social networks are not an independent force, but also interact with economic and political realities to produce the global migration patterns we observe.

The Lens of Skill

For ease of presentation, we have up to now treated migrants as a relatively homogeneous group that faces similar push and pull factors throughout the decision-making process. Of course, not all migrants experience the same economic, political, and social incentives in the same way at each stage of the decision-making process. Perhaps the most salient differentiating feature of migrants is skill or education level. Generally, one can discuss a spectrum of skill and education level for current migrants, from relatively less educated (having attained a high school degree or less) to relatively more educated (having attained a college or post-graduate degree). The factors presented here that influence destination choice interact with a migrant’s skill level to produce differing destination choice patterns.

A migrant’s level of education, or human capital, often serves as a filter for the political treatment he or she anticipates in a particular destination country. For instance, the American public has a favorable view of highly educated migrants who hold higher-status jobs, while simultaneously having an opposite view of migrants who have less job training and do not hold a college degree (Hainmueller & Hiscox, 2010 ; Hainmueller & Hopkins, 2015 ). Indeed, the political discourse surrounding migration often emphasizes skill level and education as markers of migrants who “should be” admitted, across both countries and the ideological spectrum. 6 While political tolerance may be a condition of entry for migrants in the aggregate, the relatively privileged status of highly educated and skilled migrants in most destination countries may mean that this condition is not as salient.

While it is still an open question to what extent immigration policy influences international migration, it is clear that not all migrants face evenly applied migration restrictions. Most attractive destination countries have policies that explicitly favor highly skilled migrants, since these individuals often fill labor shortages in advanced industries such as high technology and applied science. Countries such as Australia, Canada, and New Zealand all employ so-called “points-based” immigration systems in which those with advanced degrees and needed skills are institutionally favored for legal entry (Papademetriou & Sumption, 2011 ). Meanwhile, the United States maintains the H-1B visa program, which is restricted by educational attainment and can only be used to fill jobs in which no native talent is available (USCIS). Even if destination countries decide to adopt more restrictive immigration policies, the move toward restriction has typically been focused on low-skilled migrants (Peters, 2017 ). In other words, even if immigration policy worldwide becomes more restrictive, this will almost certainly not occur at the expense of highly skilled migrants and will not prevent them choosing their most preferred destination.

Bring It on Home to Me

This article began by asserting that international labor migration is an important piece of globalization, as significant as cross-border flows of capital, goods, and services. This section argues that migrant flows enhance flows of capital and commodities. Uniquely modern conditions such as advanced telecommunications, affordable and efficient international travel, and the liberalization of financial flows mean that diasporas—populations of migrants living outside their countries of origin—and home countries often re-engage with each other (Vertovec, 2004 ; Waldinger, 2008 ). This section reviews some of the newest and most thought-provoking research on international labor migration, research that explores diaspora re-engagement and how that re-engagement alters international flows of income, portfolio and foreign direct investment (FDI), trade, and migratory flows themselves.

Remittances

As previously argued, migration is often driven by the prospect of higher wages. Rational, utility-maximizing migrants incur the cost of migration in order to earn increased income that they could not earn at home. But when migrants obtain higher wages, this additional increment to income is not always designated for individual consumption. Often, migrants use their new income to send remittances, direct transfers of money from one individual to another across national borders. Once a marginal financial flow, in 2015 remittances totaled $431 billion, far outpacing foreign aid ($135 billion) and nearly passing private debt and portfolio equity ($443 billion). More than 70% of total global remittances flow into developing countries (World Bank, 2016 ). In comparison with other financial flows such as portfolio investment and FDI, remittances are more impervious to economic crises, suggesting that they may be a countercyclical force to global downturns (Leblang, 2017 ).

Remittances represent one of the most common ways in which migrants re-engage with their homeland and alter both global income flows and distribution. Why do migrants surrender large portions of their new income, supposedly the very reason they migrated in the first place, to their families back home? New economics of labor migration (NELM) theory argues that immigration itself is motivated by a family’s need or demand for remittances—that remittances are an integral part of a family’s strategy for diversifying household financial risk (Stark & Bloom, 1985 ). Remittances “are a manifestation of informal contractual agreements between migrants and the households from which they move,” indicating that remitting is not an individual-level or purely altruistic action but rather occurs in a larger social context, that of one’s immediate or extended family (European Asylum Support Office, 2016 , p. 15).

The impact of migrant remittances on countries of origin is multifaceted yet somewhat ambiguous. Most scholarly work focuses on whether remittances positively or negatively influence existing economic conditions. A number of studies find that remittances modestly reduce poverty levels in developing countries (Adams & Page, 2005 ; Yang & Martinez, 2006 ; Acosta, Calderon, Fajnzybler, & Lopez, 2008 ; Lokshin, Bontch-Osmolovski, & Glinskaya, 2010 ). On other measures of economic well-being, such as growth, inequality, and health, the literature is quite mixed and no definitive conclusions can be drawn. For instance, some studies find that remittances encourage investment in human capital (Yang, 2008 ; Adams & Cuecuecha, 2010 ), while others find no such effect and suggest that families typically spend remittances on non-productive consumption goods (Chami, Fullenkamp, & Jahjah, 2003 ). Here we can only scratch the surface of the empirical work on remittances and economic outcomes. 7

Some of the most recent research in the field argues that remittances have a distinct political dimension, affecting regime support in developing countries and altering the conditions in which elections are held. Ahmed ( 2012 ), grouping remittances with foreign aid, argues that increased remittances allow autocratic governments to extend their tenure in office. These governments can strategically channel unearned government and household income to finance political patronage networks, which leads to a reduced likelihood of autocratic turnover, regime collapse, and mass protests against the regime. More recent research posits nearly the exact opposite: remittances are linked to a greater likelihood of democratization under autocratic regimes. Escriba-Folch, Meseguer, and Wright ( 2015 ) argue that since remittances directly increase household incomes, they reduce voter reliance on political patronage networks, undermining a key tool of autocratic stability.

Remittances may also play an important role in countries with democratic institutions, yet more research is needed to fully understand the conditions under which they matter and their substantive impact. Particularly, remittances may alter the dynamics of an election as an additional and external financial flow. There is evidence of political remittance cycles : the value of remittances spikes in the run-up to elections in developing countries. The total value of remittances to the average developing country increases by 6.6% during election years, and by 12% in elections in which no incumbent or named successor is running (O’Mahony, 2012 ). The effect is even larger in the poorest of developing countries. Finer-grained tests of this hypothesis provide additional support: using monthly and quarterly data confirms the existence of political remittance cycles, as well as using subnational rather than cross-national data (Nyblade & O’Mahony, 2014 ). However, these studies do not reveal why remittances spike, or what the effects of that spike are on electoral outcomes such as vote share, campaign financing, and political strategy.

Remittances represent a massive international financial flow that warrants more scholarly attention. While there are numerous studies on the relationship between remittances and key economic indicators, there remains much room for further work on their relationship to political outcomes in developing countries. Do remittances hasten the downfall of autocratic regimes, or do they contribute to autocratic stability? In democratic contexts, do remittances substantively influence electoral outcomes, and if so, which outcomes and how? Finally, do remittances prevent even more migration because they allow one “breadwinner from abroad” to provide for the household that remains in the homeland? While data limitations are formidable, these questions are important to the study of both international and comparative political economy.

Bilateral Trade

The argument that migrant or co-ethnic networks play an important role in international economic exchange is not novel. Greif ( 1989 , 1993 ) illustrates the role that the Maghrebi traders of the 11th century played in providing informal institutional guarantees that facilitated trade. This is but a single example. Cowen’s historical survey identifies not only the Phoenicians but also the “Spanish Jews [who] were indispensable for international commerce in the Middle Ages. The Armenians controlled the overland route between the Orient and Europe as late as the nineteenth century . Lebanese Christians developed trade between the various parts of the Ottoman empire” (Cowen, 1997 , p. 170). Rauch and Trindade ( 2002 ) provide robust empirical evidence linking the Chinese diaspora to patterns of imports and exports with their home country.

A variety of case studies document the importance of migrant networks in helping overcome problems of information asymmetries. In his study of Indian expatriates residing in the United States, Kapur ( 2014 ) documents how that community provides U.S. investors with a signal of the work ethic, labor quality, and business culture that exists in India. Likewise, Weidenbaum and Hughes ( 1996 ) chronicle the Bamboo Network—the linkages between ethnic Chinese living outside mainland China and their homeland—and how these linkages provide superior access to information and opportunities for investment.

Connections between migrant communities across countries affect cross-national investment even when these connections do not provide information about investment opportunities. In his work on the Maghrebi traders of the 11th century , Greif argues that this trading network was effective because it was able to credibly threaten collective punishment by all merchants if even one of them defected (Greif, 1989 , 1993 ). Grief shows that this co-ethnic network was able to share information regarding the past actions of actors (they could communicate a reputation)—something that was essential for the efficient functioning of markets in the absence of formal legal rules. Weidenbaum and Hughes reach a similar conclusion about the effectiveness of the Bamboo Network, remarking that “if a business owner violates an agreement, he is blacklisted. This is far worse than being sued, because the entire Chinese networks will refrain from doing business with the guilty party” (Hughes, 1996 , p. 51).

Migrants not only alter the flow of income by remitting to their countries of origin, but also influence patterns of international portfolio investment and FDI. Most existing literature on international capital allocation emphasizes monadic factors such as the importance of credible commitments and state institutional quality, failing to address explicitly dyadic phenomena that may also drive investment. Diaspora networks, in particular, facilitate cross-border investment in a number of ways. They foster a higher degree of familiarity between home and host countries, leading to a greater preference for investment in specific countries. Diaspora networks can also decrease information asymmetries in highly uncertain international capital markets in two ways. Firstly, they can provide investors with salient information about their homeland, such as consumer tastes, that can influence investment decision-making. Secondly, they can share knowledge about investment opportunities, regulation and procedures, and customs that decrease transaction costs associated with cross-border investment (Leblang, 2010 ). This place of importance for migrants suggests to the broader international political economy literature the importance of non-institutional mechanisms for channeling economic activity.

Although the hypothesized link between migrants and international investment has only recently been identified, the quantitative evidence available supports that hypothesis. Leblang ( 2010 ), using dyadic cross-sectional data, finds that diaspora networks “have both a substantively significant effect and a statistically significant effect on cross-border investment,” including international portfolio investment and FDI (p. 584). The effect of bilateral migratory flows correlates positively with the degree of information asymmetry: when informational imperfections are more pervasive in a dyad, migrants (especially the highly skilled) play a disproportionately large role in international capital allocation (Kugler, Levinthal, & Rapoport, 2017 ). Other quantitative studies find substantively similar results for FDI alone (e.g., Javorcik, Özden, Spatareanu, & Neagu, 2011 ; Aubry, Rapoport, & Reshef, 2016 ).

Many questions still remain unanswered. Firstly, does the effect of migrants on investment follow the waves of the global economy, or is it countercyclical as remittances have been shown to be? Secondly, how does this additional investment, facilitated by migrants, affect socioeconomic outcomes such as inequality, poverty, and economic development (Leblang, 2010 )? Does the participation of migrants lead to more successful FDI projects in developing countries because of their ability to break down information barriers? Within portfolio investment, do migrants lead to a preference for certain asset classes over others, and if so, what are the effects on bilateral and international capital markets? These are just a few directions in an area ripe for additional research.

Return Migration and Dual Citizenship

Besides financial flows, migrants themselves directly contribute to global flows of capital by returning to their countries of origin in large numbers. This phenomenon of return migration—or circular migration—can come in a few temporal forms, including long-term migration followed by a permanent return to a country of origin, or repeat migration in which a migrant regularly moves between destination and origin countries (Dumont & Spielvogel, 2008 ). While comparable data on return migration is scarce, some reports suggest that 20% to 50% of all immigrants leave their destination country within five years after their arrival (e.g., Borjas & Bratsberg, 1996 ; Aydemir & Robinson, 2008 ; Bratsberg, Raaum, & Sørlie, 2007 ; Dustmann & Weiss, 2007 ). An independent theoretical and empirical account of return migration does not yet exist in the literature and is beyond the scope of this paper. But in the rational actor framework, motivations to return home include a failure to realize the expected benefits of migration, changing preferences toward a migrant’s home country, achievement of a savings or other economic goal, or the opening of additional employment opportunities back home due to newly acquired experience or greater levels of economic development (Dumont & Spielvogel, 2008 ).

While most migration literature treats the country of origin as a passive actor that only provides the conditions for migration, new literature on return migration gives home country policies pride of place. Origin countries can craft policies that encourage diaspora re-engagement, incentivizing individuals to return home. Dual citizenship, for example, is an extension of extraterritorial rights, allowing migrants to retain full legal status in their home country. Dual citizenship “decreases the transaction costs associated with entering a host country’s labor market and makes it easier for migrants to return home” (Leblang, 2017 , p. 77). This leads migrants to invest their financial resources in the form of remittances back home as well as their valuable human capital. When states provide such extraterritorial rights, expatriates are 10% more likely to remit and 3% more likely to return home. Dual citizenship is also associated with a doubling of the dollar amount of remittances received by a home country (Leblang, 2017 ). These striking results suggest that in addition to the power of migrants to affect cross-border flows of money and people, countries of origin can also play a significant role.

Conclusion and Future Directions

This brief article has attempted to synthesize a broad range of literature from political science, economics, sociology, migration studies, and more to construct an account of international labor migration. To do so, the migratory process was broken down into distinct stages and decision points, focusing particularly on the decision to migrate, destination choice, and the re-engagement of migrants with their homeland. In doing so, the article also discussed the interlinkages of international migration with other fields of study in international political economy, including cross-border financial flows, trade, and investment. Through a multiplicity of approaches, we have gained a greater understanding of why people decide to move, why they decide to move to one country over another, and how and why they engage with the global economy and their homeland. Despite this intellectual progress, there remain many paths for future research at each stage of the migratory process; we highlight just a few of them here.

We know that income differentials, social ties, and local political conditions are important variables influencing the migration process. Yet the question remains: why do a small but growing number of people choose to leave while the overwhelming majority of people remain in their country of birth? Here, individual- or family-level subjective characteristics may be significant. There are a handful of observational studies that explore the relationship between subjective well-being or life satisfaction and the intention to migrate, with the nascent consensus being that life dissatisfaction increases the intention to migrate (Cai, Esipova, Oppenheimer, & Feng, 2014 ; Otrachshenko & Popova, 2014 ; Nikolova & Graham, 2015 ). But more research on intrinsic or subjective measures is needed to understand (a) their independent importance more fully and (b) how they interact with objective economic, political, and social factors. For instance, do those who are more optimistic migrate in larger numbers? Do minority individuals who feel they live in an environment in which diversity is not accepted feel a greater urge to leave home? Synthesizing these types of subjective variables and perceptions with the more prominent gravity-style models could result in a more complete picture of the international migration process.

For the “typical” migrant, one who is relatively less educated than the population in the chosen destination and does not have specialized skills, social networks are key to minimizing the risk of migrating and quickly tapping into economic opportunities in destination countries. Does this remain true for those who are highly educated? Although little empirical research exists on the topic, greater human capital and often-accompanying financial resources may operate as a substitute for the advantages offered by social networks, such as housing, overcoming linguistic barriers, and finding gainful employment. This would indicate that the “friends and family effect” is not as influential for this subset of migrants. Economic considerations, such as which destination offers the largest relative wage differential, or political considerations, such as the ease of quickly acquiring full citizenship rights, may matter more for the highly skilled. Neoclassical economic models of migration may best capture the behavior of migrants who hold human capital and who have the financial resources to independently migrate in a way that maximizes income or utility more broadly.

Since we have focused on international migration as a series of discrete decision points in this article, we have perhaps underemphasized the complexity of the physical migration process. In reality, migrants often do not pick a country and travel directly there, but travel through (perhaps several) countries of transit such as Mexico, Morocco, or Turkey along the way (Angel Castillo, 2006 ; Natter, 2013 ; Icduygu, 2005 ). There is little existing theoretical work to understand the role of transit countries in the migratory process, with much of it focusing on the potential for cooperation between destination and transit countries in managing primarily illegal immigration (Kahana & Lecker, 2005 ; Djajic & Michael, 2014 ; Djajic & Michael, 2016 ). Another related strand of the literature focuses on how wealthy destination countries are “externalizing” their immigration policy, encompassing a broader part of the migratory process than simply crossing a physically demarcated border (Duvell, 2012 ; Menjivar, 2014 ). But many questions remain, such as the following: how do we understand those who desire to enter, say, the United States, but instead relocate permanently to Mexico along the way? How do countries of transit handle the pressure of transit migrants, and how does this affect economic and political outcomes in these countries?

Finally, the focus of nearly all literature on international migration (and this article as a byproduct) implicitly views advanced economies as the only prominent destinations. However, this belies the fact that 38% of all migration stays within the “Global South” (World Bank, 2016 ). While there is certainly some literature on this phenomenon (see Ratha & Shaw, 2007 ; Gindling, 2009 ; Hujo & Piper, 2007 ), international political economy scholars have yet to sufficiently tackle this topic. The overarching research question here is: do the same push and pull factors that influence the decision to migrate and destination choice apply to those who migrate within the Global South? Do we need to construct new theories of international migration with less emphasis on factors such as wage differentials and political tolerance, or are these sufficient to understand this facet of the phenomenon? If we fail to answer these questions, we may miss explaining a significant proportion of international migration with its own consequences and policy implications.

1. Our use of the term international labor migration follows academic and legal conventions; we use the term migration to refer to the voluntary movement of people across national borders, either in a temporary or permanent fashion. This excludes any discussion of refugees, asylum seekers, or any other groups that are forced to migrate.

2. We do not have space in this article to delve into the theoretical and empirical work unpacking the effect of demographic characteristics—age, gender, marital status, household size, and so forth on the migration decision and on subsequent flows of migrants. For comprehensive reviews, see Lichter ( 1983 ), Morrison and Lichter ( 1988 ); United Nations Population Division ( 2013 ); and Zaiceva and Zimmerman ( 2014 ).

3. Zelinsky ( 1971 ) originally identified this relationship and termed it mobility transition curve . A wealth of empirical work supports Zelinsky’s descriptive theory in a number of contexts (see Akerman, 1976 ; Gould, 1979 ; Hatton & Williamson, 1994 ; and Dao et al., 2016 ).

4. For a review of the arguments as well as some empirical tests, see Miller and Peters ( 2018 ) and Docquier, Lodigiani, Rapoport, and Schiff ( 2018 ).

5. Transparency International. “What is corruption?”

6. For example, former United Kingdom Independence Party leader Nigel Farage has called for the United Kingdom to adopt an immigration system that only allows in highly skilled migrants (“UKIP launches immigration policy”). In 2014, US President Barack Obama emphasized that he wanted to attract international students to American universities and that they “create jobs, businesses, and industries right here in America” (USA Today: “Full text: Obama’s immigration speech”). A key issue in Germany’s 2018 government formation was the creation of skill-based migration laws (Severin & Martin, 2018 ).

7. For a more comprehensive review, see Rapoport and Docquier ( 2006 ); and Adams ( 2011 ).

Essay on Immigration | Causes & Effects

December 4, 2017 by Study Mentor Leave a Comment

Table of Contents

What do you mean by immigration? 

Immigration refers to the movement in which people from one country move to another country for various reasons. They go to another country where they do not have the right to citizenship. This means that they are not the natives of that country.

They move to a new country so that they can settle there, become the citizens of that country, be a worker there and many other reasons. In the history we can see that even animals have moved to another place along with the humans on the early age.

The terms migration, immigration and emigration revolve around the same thing but have different meanings. There has been an increase in the count of people involved in immigration. US has been the destination of most immigrants. Mostly these immigrants have come from Europe or Asia.   

The factors which encourage immigration come under two categories. These two categories are known as push and pull factors. From the terms itself, it can be easily understood what they mean. The push factors mean the people are going away from their place to another because of these factors.

These factors may be like low wage, unemployment, illegal activities, oppression, no technology, improper facilities of life and many other factors. Due to factors like these people leave their country. While the pull factors are the ones which bring people towards them.

These countries may have more facilities than the people’s own country. The country might have advanced facilities and technology. Even though these factors may affect a person’s decision to move to another place, there may be many barriers which a person has to face while moving.

These can be legal and political problems which one has to face. Moreover, a person will take time to get habituated with the new place.  

Reasons responsible for immigration  

Immigration takes place because of the push and pull factors. They are the positive and negative factors respectively. Immigration has been taking place from the time human first came on this planet. During that time people used to migrate in search of food and new places.

After this they wanted better place like for example better lands for settlement and cultivation. After this they started to move to another place for better facilities of their life. In order to have a proper happy life they have been moving from one place to another.

Sometimes people even move to other places due to natural disasters. They may not feel safe because these natural disasters. That is why for their safety they shift to another place. Very often some of the countries face a lot of political and religious problems.

In order to be free from all these problems they decide to shift to another place. Mostly the young and middle adulthood are the ones who are the subject of immigration. They want to get better jobs, earning opportunities and good life. They move to such a place where they think their life will be stable and they will get all the facilities necessary for their life.   

How does immigration affect the society  and economy ?  

Immigration affects the society and economy. It has both positive and negative impacts. When the people move to another country, they are referred there as immigrants. The citizens of that country feel that these immigrants are a burden for them.

This is because these new people in their country can take away their job opportunities and other facilities. According to them these immigrants act as a threat to them. But due to immigration there is economic growth, existence of dynamic and variety society and also the skills for various types of work is met.

When people with enough skills move to another country, that particular country gets a benefit because of them. Due to the payment of the taxes by the immigrants, there is increase in the collection of taxes by the government for their country. The immigrants are always ready to pay these taxes to get many services benefits in return. There is an increase in the different workplace as well.

More people are there for a particular job. This helps to increase the production in a short period of time. The economic growth of the country will increase if there are more immigrants. But if that country has problems in its borders and there are problems for outsiders to enter that country, there will not be so much of economic growth there.

Moreover, the country from where these people are shifting incurs loss in all areas. There is a fall in the economic growth and workforce diversity as well. But when people from low productivity areas shift to the areas which have high productivity the overall impact is a positive one for both the countries.   

Most often the countries where these immigrants shift get all the benefits. When people who possess a lot of skills shift to another country, there is a variety in the production of goods in that country. This variety of production will satisfy the citizens of that country.

Moreover, people who have good education qualification and work experience get the best jobs of the country. But it does not mean that the other immigrants do not get jobs. Even they get jobs but that is according to their qualification and work experience.

When the immigrants start working in a new place, they are not paid in a high amount. As the different workplaces are not spending so much on labor for the various types of work, they start to reduce the price of the goods. This acts as a benefit for the consumers. But when people shift to another country because of easily accessible facilities, that country faces problems in providing services to the public.

The ability to give service and support the people of the country reduces. Moreover, when the society becomes heterogeneous because of immigrants there might be a variety of goods for the people. But this leads to a fall in the production of the public goods of that particular country.

But despite the advantages and disadvantages of immigration, people will not stop from moving to a new place. This is a continuous cycle. Every single day at least one person shifts to a new place. This process of immigration will not be stopping ever. No matter how many problems are there with immigration still this process will continue.   

What is the difference between immigration, emigration and migration? 

People often confuse what are immigration, emigration and migration. But there is more confusion between immigration and emigration. Both these words have a very similar meaning. This is the reason why people make mistakes while using these words. But before moving into immigration and emigration, it is important to know what migration is. Migration means to move from one place to another in order to settle there.

Migration is the bigger term to define immigration and emigration. Immigrate means a person is entering to a new country while emigrate means a person is leaving country. Immigration can also be referred as inward migration and emigration can be known as outward migration. In a simpler way to explain this, immigration means “in” and emigration means “out”.

A person can be called as immigrant and emigrant at the same time. This because when he leaves his country he will be called as an emigrant. But when he enters to a new country he will called as an immigrant. This means he is emigrant for the origin country and immigrant for the destination country. Even though these two terms have different meanings, the reasons due to which these takes place are the same.

But people who are entering into a new country have to face more problems because of the rules of the new country. It is not at all easy for a person to shift to a new place. The most common problem is the language. It will be very difficult for a person to reside at a place whose language one does not know.

They will not be able to converse with the people around them. Social interaction will be very less. Knowing the language of the new country is very important because it will be helpful to get a job in that place. No matter how advanced the place is, any person will take time to get habituated to that new place.

Why do immigrants come to the US?

Of all people legally immigrating to the US in 2021, about 42% came for work, 32% for school, and 23% for family.

Updated on Fri, November 17, 2023 by the USAFacts Team

People immigrate to the US to work, reunite with family, study, or seek personal safety. In 2021, 42% of the 1.5 million people who immigrated to the US came for work.

What reasons for immigration does the government track?

The US government generally allows legal immigration for five broad reasons : work , school , family, safety, and encouraging diversity.

People immigrating for work or school are often granted temporary entry rather than permanent residency. Immigration for family generally means the immigrant has a relative who is already in the US as a citizen, green card holder, or temporary visa holder with whom they want to be reunited with. Those who immigrate for safety are refugees or asylum-seekers. And finally, up to 50,000 immigrants obtain green cards annually through the Diversity Immigrant Visa Program lottery that grants entry to individuals from countries with low rates of immigration to the US.

How many immigrants came for each reason in 2021?

Of the 1.5 million people who immigrated to the US in 2021, about 42% came for work, 32% for school, and 23% for family. Nearly 2% were seeking safety, and about 0.9% were admitted on Diversity Immigrant Visas.

How have reasons for immigration evolved over the past 15 years?

Since 2006, work has consistently been the top reason people immigrate to the US, with the exception of 2013–2015 when immigration for work was equal to or slightly lower than for school.

School is usually the second most common reason for immigration except for 2018, when a higher percentage of people began immigrating for family reunification than education. In 2021 school again became the second most common reason.

Safety and diversity have consistently been the fourth and fifth most common reasons for immigration, respectively.

Area chart showing the number of people authorized to immigrate to the US by reason, 2006–2021. The chart indicates work is the most common reason for authorized immigration.

How do the reasons for immigration change depending on where people are immigrating from?

Of the 638,551 immigrants who came to the US for work in 2021, 61% came from North America. Immigrants from Asia represent the largest geographic cohort among the other four primary reasons for immigration: school (58%), family (45%), safety (34%), and encouraging diversity (33%).

New authorized immigrant arrivals by reason and region of origin, 2021. People from Asia made up the largest cohort of newly arrived immigrants in 2021

In 2021, 74% of all immigrants came from Asia and North/Central America. Roughly 53% of Asian immigrants came from China and India, while nearly 80% of immigrants from North/Central America were from Mexico.

Why do Chinese people immigrate to America?

School was the top reason Chinese people immigrated between 2006–2021; 19% of people who came to the US for school were from China, the highest percentage of any other country. The number of Chinese immigrants coming to the US for school peaked in 2015, growing 680% from 40,477 people in 2006 to 315,628 people in 2015.

Despite a sharp decrease after 2016, most Chinese immigrants continue to come to the US for school. Fewer than 57,000 Chinese immigrants have come to the US per year for work or family reasons since 2006, and those numbers hit record lows of 5,323 and 13,412 in 2021.

Chart showing Number of authorized Chinese immigrants to the US by reason, 2006–2021. Since its peak in 2015, Chinese immigration for education in the US has fallen by 70.4%.

Why do Indian people immigrate to America?

The largest share of immigrants who came to be with family were from India, at 18% . But in 2021, more Indians immigrated for school than for family reunification. Work was the third most common reason.

Prior to 2021, most Indian immigrants came to the US for family and work, but those numbers have been decreasing. Fewer people came to the US from India for work (54,032 people) and family in 2021 (62,407) than in 2006 (117,189 and 81,045 people, respectively).

Meanwhile, the number of Indians immigrating for school increased by over 300% between 2020 and 2021, from 20,629 to 85,385.

Line graph showing the number of authorized Indian immigrants to the US by reason, 2006–2021. Indian immigration into the US was 45.6% lower in 2021 than before the pandemic.

Why do Mexican people immigrate to America?

In 2021, people from Mexico comprised the largest share of immigrants coming for work — 55% of all immigrants, or 351,586 people. Work has consistently been the top reason Mexican people immigrate to the US. Family and school have consistently been the second and third reasons.

More than double the number of people immigrated to the US for work from Mexico in 2021 (351,586 people) than in 2006 (168,619 people).

Line graph showing the number of authorized Mexican immigrants to the US by reason, 2006–2021. Over 82% of authorized Mexican immigrants to the US in 2021 came for work-related reasons.

Where did this data come from?

There are multiple data sources because immigrants enter the US through multiple pathways. Data on visa admissions comes from the US State Department; we exclude people who come with visas for short-term tourism, cultural exchange, or visiting. Data on refugees and asylum-seekers comes from the Department of Homeland Security's (DHS) Yearbook of Immigration Statistics.

Eight brilliant student essays on immigration and unjust assumptions.

Read winning essays from our winter 2019 “Border (In)Security” student writing contest.

map-usa .jpeg

For the winter 2019 student writing competition, “Border (In)Security,” we invited students to read the YES! Magazine article “Two-Thirds of Americans Live in the “Constitution-Free Zone” by Lornet Turnbull and respond with an up-to-700-word essay. 

Students had a choice between two writing prompts for this contest on immigration policies at the border and in the “Constitution-free zone,” a 100-mile perimeter from land and sea borders where U.S. Border Patrol can search any vehicle, bus, or vessel without a warrant. They could state their positions on the impact of immigration policies on our country’s security and how we determine who is welcome to live here. Or they could write about a time when someone made an unfair assumption about them, just as Border Patrol agents have made warrantless searches of Greyhound passengers based simply on race and clothing.

Broken Promises

“…Give me your tired, your poor,

Your huddled masses yearning to breathe free,

The wretched refuse of your teeming shore.

Send these, the homeless, tempest-tossed to me,

I lift my lamp beside the golden door!”

These words were written by Emma Lazarus and are inscribed on the base of the Statue of Liberty. And yet, the very door they talk about is no longer available to those who need it the most. The door has been shut, chained, and guarded. It no longer shines like gold. Those seeking asylum are being turned away. Families are being split up; children are being stranded. The promise America made to those in need is broken.

Not only is the promise to asylum seekers broken, but the promises made to some 200 million people already residing within the U.S. are broken, too. Anyone within 100 miles of the United States border lives in the “Constitution-free zone” and can be searched with “reasonable suspicion,” a suspicion that is determined by Border Patrol officers. The zone encompasses major cities, such as Seattle and New York City, and it even covers entire states, such as Florida, Massachusetts, and New Jersey. I live in the Seattle area, and it is unsettling that I can be searched and interrogated without the usual warrant. In these areas, there has been an abuse of power; people have been unlawfully searched and interrogated because of assumed race or religion.

The ACLU obtained data from the Customs and Border Protection Agency that demonstrate this reprehensible profiling. The data found that “82 percent of foreign citizens stopped by agents in that state are Latino, and almost 1 in 3 of those processed are, in fact, U.S. citizens.” These warrantless searches impede the trust-building process and communication between the local population and law enforcement officers. Unfortunately, this lack of trust makes campaigns, such as Homeland Security’s “If You See Something, Say Something,” ineffective due to the actions of the department’s own members and officers. Worst of all, profiling ostracizes entire communities and makes them feel unsafe in their own country.

Ironically, asylum seekers come to America in search of safety. However, the thin veil of safety has been drawn back, and, behind it, our tarnished colors are visible. We need to welcome people in their darkest hours rather than destroy their last bit of hope by slamming the door in their faces. The immigration process is currently in shambles, and an effective process is essential for both those already in the country and those outside of it. Many asylum seekers are running from war, poverty, hunger, and death. Their countries’ instability has hijacked every aspect of their lives, made them vagabonds, and the possibility of death, a cruel and unforgiving death, is real. They see no future for their children, and they are desperate for the perceived promise of America—a promise of opportunity, freedom, and a safe future. An effective process would determine who actually needs help and then grant them passage into America. Why should everyone be turned away? My grandmother immigrated to America from Scotland in 1955. I exist because she had a chance that others are now being denied.

Emma Lazarus named Lady Liberty the “Mother of Exiles.” Why are we denying her the happiness of children? Because we cannot decide which ones? America has an inexplicable area where our constitution has been spurned and forgotten. Additionally, there is a rancorous movement to close our southern border because of a deep-rooted fear of immigrants and what they represent. For too many Americans, they represent the end of established power and white supremacy, which is their worst nightmare. In fact, immigrants do represent change—healthy change—with new ideas and new energy that will help make this country stronger. Governmental agreement on a humane security plan is critical to ensure that America reaches its full potential. We can help. We can help people in unimaginably terrifying situations, and that should be our America.

essay about causes and effects of immigration

Xenophobia and the Constitution-Free Zone

In August of 2017, U.S. Border Patrol agents boarded a Greyhound bus that had just arrived at the White River Junction station from Boston. According to Danielle Bonadona, a Lebanon resident and a bus passenger, “They wouldn’t let us get off. They boarded the bus and told us they needed to see our IDs or papers.” Bonadona, a 29-year-old American citizen, said that the agents spent around 20 minutes on the bus and “only checked the IDs of people who had accents or were not white.” Bonadona said she was aware of the 100-mile rule, but the experience of being stopped and searched felt “pretty unconstitutional.”

In the YES! article “Two-Thirds of Americans Live in the ‘Constitution-Free Zone’” by Lornet Turnbull, the author references the ACLU’s argument that “the 100-mile zone violates Fourth Amendment protections against unreasonable search and seizure.” However, the Supreme Court upholds the use of immigration checkpoints for inquiries on citizenship status. In my view, the ACLU makes a reasonable argument. The laws of the 100-mile zone are blurred, and, too often, officials give arbitrary reasons to conduct a search. Xenophobia and fear of immigrants burgeons in cities within these areas. People of color and those with accents or who are non-English speakers are profiled by law enforcement agencies that enforce anti-immigrant policies. The “Constitution-free zone” is portrayed as an effective barrier to secure our borders. However, this anti-immigrant zone does not make our country any safer. In fact, it does the opposite.

As a former student from the Houston area, I can tell you that the Constitution-free zone makes immigrants and citizens alike feel on edge. The Department of Homeland Security’s white SUVs patrol our streets. Even students feel the weight of anti-immigrant laws. Dennis Rivera Sarmiento, an undocumented student who attended Austin High School in Houston, was held by school police in February 2018 for a minor altercation and was handed over to county police. He was later picked up by Immigration and Customs Enforcement (ICE) and held in a detention center. It is unfair that kids like Dennis face much harsher consequences for minor incidents than other students with citizenship.

These instances are a direct result of anti-immigrant laws. For example, the 287(g) program gives local and state police the authority to share individuals’ information with ICE after an arrest. This means that immigrants can be deported for committing misdemeanors as minor as running a red light. Other laws like Senate Bill 4, passed by the Texas Legislature, allow police to ask people about their immigration status after they are detained. These policies make immigrants and people of color feel like they’re always under surveillance and that, at any moment, they may be pulled over to be questioned and detained.

During Hurricane Harvey, the immigrant community was hesitant to go to the shelters because images of immigration authorities patrolling the area began to surface online. It made them feel like their own city was against them at a time when they needed them most. Constitution-free zones create communities of fear. For many immigrants, the danger of being questioned about immigration status prevents them from reporting crimes, even when they are the victim. Unreported crime only places more groups of people at risk and, overall, makes communities less safe.

In order to create a humane immigration process, citizens and non-citizens must hold policymakers accountable and get rid of discriminatory laws like 287(g) and Senate Bill 4. Abolishing the Constitution-free zone will also require pressure from the public and many organizations. For a more streamlined legal process, the League of United Latin American Citizens suggests background checks and a small application fee for incoming immigrants, as well as permanent resident status for Deferred Action for Childhood Arrivals (DACA) and Temporary Protected Status (TPS) recipients. Other organizations propose expanding the green card lottery and asylum for immigrants escaping the dangers of their home countries.

Immigrants who come to the U.S. are only looking for an opportunity to provide for their families and themselves; so, the question of deciding who gets inside the border and who doesn’t is the same as trying to prove some people are worth more than others. The narratives created by anti-immigrant media plant the false idea that immigrants bring nothing but crime and terrorism. Increased funding for the border and enforcing laws like 287(g) empower anti-immigrant groups to vilify immigrants and promote a witch hunt that targets innocent people. This hatred and xenophobia allow law enforcement to ask any person of color or non-native English speaker about their citizenship or to detain a teenager for a minor incident. Getting rid of the 100-mile zone means standing up for justice and freedom because nobody, regardless of citizenship, should have to live under laws created from fear and hatred.

essay about causes and effects of immigration

I’m an expert on bussing. For the past couple of months, I’ve been a busser at a pizza restaurant near my house. It may not be the most glamorous job, but it pays all right, and, I’ll admit, I’m in it for the money.

I arrive at 5 p.m. and inspect the restaurant to ensure it is in pristine condition for the 6 p.m. wave of guests. As customers come and go, I pick up their dirty dishes, wash off their tables, and reset them for the next guests. For the first hour of my shift, the work is fairly straightforward.

I met another expert on bussing while crossing the border in a church van two years ago. Our van arrived at the border checkpoint, and an agent stopped us. She read our passports, let us through, and moved on to her next vehicle. The Border Patrol agent’s job seemed fairly straightforward.

At the restaurant, 6 p.m. means a rush of customers. It’s the end of the workday, and these folks are hungry for our pizzas and salads. My job is no longer straightforward.

Throughout the frenzy, the TVs in the restaurant buzz about waves of people coming to the U.S. border. The peaceful ebb and flow enjoyed by Border agents is disrupted by intense surges of immigrants who seek to enter the U.S. Outside forces push immigrants to the United States: wars break out in the Middle East, gangs terrorize parts of Central and South America, and economic downturns force foreigners to look to the U.S., drawn by the promise of opportunity. Refugees and migrant caravans arrive, and suddenly, a Border Patrol agent’s job is no longer straightforward.

I turn from the TVs in anticipation of a crisis exploding inside the restaurant: crowds that arrive together will leave together. I’ve learned that when a table looks finished with their dishes, I need to proactively ask to take those dishes, otherwise, I will fall behind, and the tables won’t be ready for the next customers. The challenge is judging who is finished eating. I’m forced to read clues and use my discretion.

Interpreting clues is part of a Border Patrol agent’s job, too. Lornet Turnbull states, “For example, CBP data obtained by ACLU in Michigan shows that 82 percent of foreign citizens stopped by agents in that state are Latino, and almost 1 in 3 of those processed is, in fact, a U.S. citizen.” While I try to spot customers done with their meals so I can clear their part of the table, the Border Patrol officer uses clues to detect undocumented immigrants. We both sometimes guess incorrectly, but our intentions are to do our jobs to the best of our abilities.

These situations are uncomfortable. I certainly do not enjoy interrupting a conversation to get someone’s dishes, and I doubt Border Patrol agents enjoy interrogating someone about their immigration status. In both situations, the people we mistakenly ask lose time and are subjected to awkward and uncomfortable situations. However, here’s where the busser and the Border Patrol officer’s situations are different: If I make a mistake, the customer faces a minor inconvenience. The stakes for a Border Patrol agent are much higher. Mistakenly asking for documentation and searching someone can lead to embarrassment or fear—it can even be life-changing. Thus, Border Patrol agents must be fairly certain that someone’s immigration status is questionable before they begin their interrogation.

To avoid these situations altogether, the U.S. must make the path to citizenship for immigrants easier. This is particularly true for immigrants fleeing violence. Many people object to this by saying these immigrants will bring violence with them, but data does not support this view. In 1939, a ship of Jewish refugees from Germany was turned away from the U.S.—a decision viewed negatively through the lens of history. Today, many people advocate restricting immigration for refugees from violent countries; they refuse to learn the lessons from 1939. The sad thing is that many of these immigrants are seen as just as violent as the people they are fleeing. We should not confuse the oppressed with the oppressor.

My restaurant appreciates customers because they bring us money, just as we should appreciate immigrants because they bring us unique perspectives. Equally important, immigrants provide this country with a variety of expert ideas and cultures, which builds better human connections and strengthens our society.

essay about causes and effects of immigration

Detained on the Road to Equality

The United States is a nation of immigrants. There are currently 43 million foreign-born people living in the U.S. Millions of them are naturalized American citizens, and 23 million, or 7.2 percent of the population, are living here without documentation (US Census, 2016). One in seven residents of the United States was not born here. Multiculturalism is, and always has been, a key part of the American experience. However, romantic notions of finding a better life in the United States for immigrants and refugees don’t reflect reality. In modern history, America is a country that systematically treats immigrants—documented or not—and non-white Americans in a way that is fundamentally different than what is considered right by the majority.

The Equal Protection Clause of the Fourteenth Amendment states,“No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.” When a suspected undocumented immigrant is detained, their basic human rights are violated. Warrantless raids on Greyhound buses within 100 miles of the border (an area referred to by some as the “Constitution-free zone”) are clear violations of human rights. These violations are not due to the current state of politics; they are the symptom of blatant racism in the United States and a system that denigrates and abuses people least able to defend themselves.

It is not surprising that some of the mechanisms that drive modern American racism are political in nature. Human beings are predisposed to dislike and distrust individuals that do not conform to the norms of their social group (Mountz, Allison). Some politicians appeal to this suspicion and wrongly attribute high crime rates to non-white immigrants. The truth is that immigrants commit fewer crimes than native-born Americans. In fact, people born in the United States are convicted of crimes at a rate twice that of undocumented non-natives (Cato Institute, 2018).

The majority of immigrants take high risks to seek a better life, giving them incentive to obey the laws of their new country. In many states, any contact with law enforcement may ultimately result in deportation and separation from family. While immigrants commit far fewer crimes, fear of violent crime by much of the U.S. population outweighs the truth. For some politicians, it is easier to sell a border wall to a scared population than it is to explain the need for reformed immigration policy. It’s easier to say that immigrants are taking people’s jobs than explain a changing global economy and its effect on employment. The only crime committed in this instance is discrimination.

Human rights are violated when an undocumented immigrant—or someone perceived as an undocumented immigrant—who has not committed a crime is detained on a Greyhound bus. When a United States citizen is detained on the same bus, constitutional rights are being violated. The fact that this happens every day and that we debate its morality makes it abundantly clear that racism is deeply ingrained in this country. Many Americans who have never experienced this type of oppression lack the capacity to understand its lasting effect. Most Americans don’t know what it’s like to be late to work because they were wrongfully detained, were pulled over by the police for the third time that month for no legal reason, or had to coordinate legal representation for their U.S. citizen grandmother because she was taken off a bus for being a suspected undocumented immigrant. This oppression is cruel and unnecessary.

America doesn’t need a wall to keep out undocumented immigrants; it needs to seriously address how to deal with immigration. It is possible to reform the current system in such a way that anyone can become a member of American society, instead of existing outside of it. If a person wants to live in the United States and agrees to follow its laws and pay its taxes, a path to citizenship should be available.

People come to the U.S. from all over the world for many reasons. Some have no other choice. There are ongoing humanitarian crises in Syria, Yemen, and South America that are responsible for the influx of immigrants and asylum seekers at our borders. If the United States wants to address the current situation, it must acknowledge the global factors affecting the immigrants at the center of this debate and make fact-informed decisions. There is a way to maintain the security of America while treating migrants and refugees compassionately, to let those who wish to contribute to our society do so, and to offer a hand up instead of building a wall.

essay about causes and effects of immigration

An Emotion an Immigrant Knows Too Well

Before Donald Trump’s campaign, I was oblivious to my race and the idea of racism. As far as I knew, I was the same as everyone else. I didn’t stop to think about our different-colored skins. I lived in a house with a family and attended school five days a week just like everyone else. So, what made me different?

Seventh grade was a very stressful year—the year that race and racism made an appearance in my life. It was as if a cold splash of water woke me up and finally opened my eyes to what the world was saying. It was this year that Donald Trump started initiating change about who got the right to live in this country and who didn’t. There was a lot of talk about deportation, specifically for Mexicans, and it sparked commotion and fear in me.

I remember being afraid and nervous to go out. At home, the anxiety was there but always at the far back of my mind because I felt safe inside. My fear began as a small whisper, but every time I stepped out of my house, it got louder. I would have dreams about the deportation police coming to my school; when I went to places like the library, the park, the store, or the mall, I would pay attention to everyone and to my surroundings. In my head, I would always ask myself, “Did they give us nasty looks?,” “Why does it seem quieter?” “Was that a cop I just saw?” I would notice little things, like how there were only a few Mexicans out or how empty a store was. When my mom went grocery shopping, I would pray that she would be safe. I was born in America, and both my parents were legally documented. My mom was basically raised here. Still, I couldn’t help but feel nervous.

I knew I shouldn’t have been afraid, but with one look, agents could have automatically thought my family and I were undocumented. Even when the deportation police would figure out that we weren’t undocumented, they’d still figure out a way to deport us—at least that was what was going through my head. It got so bad that I didn’t even want to do the simplest things like go grocery shopping because there was a rumor that the week before a person was taken from Walmart.

I felt scared and nervous, and I wasn’t even undocumented. I can’t even imagine how people who are undocumented must have felt, how they feel. All I can think is that it’s probably ten times worse than what I was feeling. Always worrying about being deported and separated from your family must be hard. I was living in fear, and I didn’t even have it that bad. My heart goes out to families that get separated from each other. It’s because of those fears that I detest the “Constitution-free zone.”

Legally documented and undocumented people who live in the Constitution-free zone are in constant fear of being deported. People shouldn’t have to live this way. In fact, there have been arguments that the 100-mile zone violates the Fourth Amendment, which gives people the right to be protected from unreasonable searches and seizures of property by the government. Unfortunately, the U.S. Supreme Court has consistently upheld these practices.

One question that Lornet Turnbull asks in her YES! article “Two-Thirds of Americans Live in the ‘Constitution-Free Zone’” is, “How should we decide who is welcome in the U.S and who is not?” Instead of focusing on immigrants, how about we focus on the people who shoot up schools, rape girls, exploit women for human sex trafficking, and sell drugs? These are the people who make our country unsafe; they are the ones who shouldn’t be accepted. Even if they are citizens and have the legal right to live here, they still shouldn’t be included. If they are the ones making this country unsafe, then what gives them the right to live here?

I don’t think that the Constitution-free zone is an effective and justifiable way to make this country more “secure.” If someone isn’t causing any trouble in the United States and is just simply living their life, then they should be welcomed here. We shouldn’t have to live in fear that our rights will be taken away. I believe that it’s unfair for people to automatically think that it’s the Hispanics that make this country unsafe. Sure, get all the undocumented people out of the United States, but it’s not going to make this country any safer. It is a society that promotes violence that makes us unsafe, not a race.

essay about causes and effects of immigration

Hold Your Head High and Keep Those Fists Down

How would you feel if you walked into a store and salespeople were staring at you? Making you feel like you didn’t belong. Judging you. Assuming that you were going to take something, even though you might have $1,000 on you to spend. Sometimes it doesn’t matter. This is because people will always judge you. It might not be because of your race but for random reasons, like because your hair is black instead of dirty blonde. Or because your hair is short and not long. Or just because they are having a bad day. People will always find ways to bring you down and accuse you of something, but that doesn’t mean you have to go along with it.

Every time I entered a store, I would change my entire personality. I would change the way I talked and the way I walked. I always saw myself as needing to fit in. If a store was all pink, like the store Justice, I would act like a girly girl. If I was shopping in a darker store, like Hot Topic, I would hum to the heavy metal songs and act more goth. I had no idea that I was feeding into stereotypes.

When I was 11, I walked into Claire’s, a well-known store at the mall. That day was my sister’s birthday. Both of us were really happy and had money to spend. As soon as we walked into the store, two employees stared me and my sister down, giving us cold looks. When we went to the cashier to buy some earrings, we thought everything was fine. However, when we walked out of the store, there was a policeman and security guards waiting. At that moment, my sister and I looked at one another, and I said, in a scared little girl voice, “I wonder what happened? Why are they here?”

Then, they stopped us. We didn’t know what was going on. The same employee that cashed us out was screaming as her eyes got big, “What did you steal?” I was starting to get numb. Me and my sister looked at each other and told the truth: “We didn’t steal anything. You can check us.” They rudely ripped through our bags and caused a big scene. My heart was pounding like a drum. I felt violated and scared. Then, the policeman said, “Come with us. We need to call your parents.” While this was happening, the employees were talking to each other, smiling. We got checked again. The police said that they were going to check the cameras, but after they were done searching us, they realized that we didn’t do anything wrong and let us go about our day.

Walking in the mall was embarrassing—everybody staring, looking, and whispering as we left the security office. This made me feel like I did something wrong while knowing I didn’t. We went back to the store to get our shopping bags. The employees sneered, “Don’t you niggers ever come in this store again. You people always take stuff. This time you just got lucky.” Their faces were red and frightening. It was almost like they were in a scary 3D movie, screaming, and coming right at us. I felt hurt and disappointed that someone had the power within them to say something so harsh and wrong to another person. Those employees’ exact words will forever be engraved in my memory.

In the article, “Two-Thirds of Americans Live in the ‘Constitution-Free Zone’,” Lornet Turnbull states, “In January, they stopped a man in Indio, California, as he was boarding a Los Angeles-bound bus. While questioning this man about his immigration status, agents told him his ‘shoes looked suspicious,’ like those of someone who had recently crossed the border.” They literally judged him by his shoes. They had no proof of anything. If a man is judged by his shoes, who else and what else are being judged in the world?

In the novel  To Kill a Mockingbird , a character named Atticus states, “You just hold your head high and keep those fists down. No matter what anybody says to you, don’t you let’em get your goat. Try fighting with your head for a change.” No matter how much you might try to change yourself, your hairstyle, and your clothes, people will always make assumptions about you. However, you never need to change yourself to make a point or to feel like you fit in. Be yourself. Don’t let those stereotypes turn into facts.

 Wielding My Swords

If I were a swordsman, my weapons would be my identities. I would wield one sword in my left hand and another in my right. People expect me to use both fluently, but I’m not naturally ambidextrous. Even though I am a right-handed swordsman, wielding my dominant sword with ease, I must also carry a sword in my left, the heirloom of my family heritage. Although I try to live up to others’ expectations by using both swords, I may appear inexperienced while attempting to use my left. In some instances, my heirloom is mistaken for representing different families’ since the embellishments look similar.

Many assumptions are made about my heirloom sword based on its appearance, just as many assumptions are made about me based on my physical looks. “Are you Chinese?” When I respond with ‘no,’ they stare at me blankly in confusion. There is a multitude of Asian cultures in the United States, of which I am one. Despite what many others may assume, I am not Chinese; I am an American-born Korean.

“Then… are you Japanese?” Instead of asking a broader question, like “What is your ethnicity?,” they choose to ask a direct question. I reply that I am Korean. I like to think that this answers their question sufficiently; however, they think otherwise. Instead, I take this as their invitation to a duel.

They attack me with another question: “Are you from North Korea or South Korea?” I don’t know how to respond because I’m not from either of those countries; I was born in America. I respond with “South Korea,” where my parents are from because I assume that they’re asking me about my ethnicity. I’m not offended by this situation because I get asked these questions frequently. From this experience, I realize that people don’t know how to politely ask questions about identity to those unlike them. Instead of asking “What is your family’s ethnicity?,” many people use rude alternatives, such as “Where are you from?,” or “What language do you speak?”

When people ask these questions, they make assumptions based on someone’s appearance. In my case, people make inferences like:

“She must be really good at speaking Korean.”

“She’s Asian; therefore, she must be born in Asia.”

“She’s probably Chinese.”

These thoughts may appear in their heads because making assumptions is natural. However, there are instances when assumptions can be taken too far. Some U.S. Border Patrol agents in the “Constitution-free zone” have made similar assumptions based on skin color and clothing. For example, agents marked someone as an undocumented immigrant because “his shoes looked suspicious, like those of someone who had recently crossed the border.”

Another instance was when a Jamaican grandmother was forced off a bus when she was visiting her granddaughter. The impetus was her accent and the color of her skin. Government officials chose to act on their assumptions, even though they had no solid proof that the grandmother was an undocumented immigrant. These situations just touch the surface of the issue of racial injustice in America.

When someone makes unfair assumptions about me, they are pointing their sword and challenging me to a duel; I cannot refuse because I am already involved. It is not appropriate for anyone, including Border Patrol agents, to make unjustified assumptions or to act on those assumptions. Border Patrol agents have no right to confiscate the swords of the innocent solely based on their conjectures. The next time I’m faced with a situation where racially ignorant assumptions are made about me, I will refuse to surrender my sword, point it back at them, and triumphantly fight their ignorance with my cultural pride.

We Are Still Dreaming

As a young Muslim American woman, I have been labeled things I am not: a terrorist, oppressed, and an ISIS supporter. I have been accused of planning 9/11, an event that happened before I was born. Lately, in the media, Muslims have been portrayed as supporters of a malevolent cause, terrorizing others just because they do not have the same beliefs. I often scoff at news reports that portray Muslims in such a light, just as I scoff at all names I’ve been labeled. They are words that do not define me. 

In a land where labels have stripped immigrants of their personalities, they are now being stripped of something that makes them human: their rights. The situation described in Lornet Turnbull’s article, “Two-Thirds of Americans are Living in the ‘Constitution-Free Zone’,” goes directly against the Constitution, the soul of this country, something that asserts that we are all equal before the law. If immigrants do not have protection from the Constitution, is there any way to feel safe?

Although most insults are easy to shrug off, they are still threatening. I am ashamed when I feel afraid to go to the mosque. Friday is an extremely special day when we gather together to pray, but lately, I haven’t been going to the mosque for Jummah prayers. I have realized that I can never feel safe when in a large group of Muslims because of the widespread hatred of Muslims in the United States, commonly referred to as Islamophobia. Police surround our mosque, and there are posters warning us about dangerous people who might attack our place of worship because we have been identified as terrorists.

I wish I could tune out every news report that blasts out the headline “Terrorist Attack!” because I know that I will be judged based on the actions of someone else. Despite this anti-Muslim racism, what I have learned from these insults is that I am proud of my faith. I am a Muslim, but being Muslim doesn’t define me. I am a writer, a student, a dreamer, a friend, a New Yorker, a helper, and an American. I am unapologetically me, a Muslim, and so much more. I definitely think everyone should get to know a Muslim. They would see that some of us are also Harry Potter fans, not just people planning to bomb the White House.

Labels are unjustly placed on us because of the way we speak, the color of our skin, and what we believe in—not for who we are as individuals. Instead, we should all take more time to get to know one another. As Martin Luther King Jr. said in his “I Have a Dream” speech, we should be judged by the content of our character and not the color of our skin. To me, it seems Martin Luther King Jr.’s dream is a dream that should be a reality. But, for now, we are dreaming.

Aminata Toure is a Guinean American Muslim student. Aminata loves spoken-word poetry and performs in front of hundreds of people at her school’s annual poetry slam. She loves writing, language, history, and West African food and culture. Aminata wants to work at the United Nations when she grows up.

From the Author 

Dear Alessandra, Cain, Daniel, Tiara, Emma, Hailee, Aminata and Ethan,

I am moved and inspired by the thought each of you put into your responses to my story about this so-called “Constitution-free zone.” Whether we realize it or not, immigration in this country impacts all of us— either because we are immigrants ourselves, have neighbors, friends, and family who are, or because we depend on immigrants for many aspects of our lives—from the food we put on our tables to the technology that bewitches us. It is true that immigrants enrich our society in so many important ways, as many of you point out.

And while the federal statute that permits U.S. Border Patrol officers to stop and search at will any of the 200 million of us in this 100-mile shadow border, immigrants have been their biggest targets. In your essays, you highlight how unjust the law is—nothing short of racial profiling. It is heartening to see each of you, in your own way, speaking out against the unfairness of this practice.

Alessandra, you are correct, the immigration system in this country is in shambles. You make a powerful argument about how profiling ostracizes entire communities and how the warrantless searches allowed by this statute impede trust-building between law enforcement and the people they are called on to serve.

And Cain, you point out how this 100-mile zone, along with other laws in the state of Texas where you attended school, make people feel like they’re “always under surveillance, and that, at any moment, you may be pulled over to be questioned and detained.” It seems unimaginable that people live their lives this way, yet millions in this country do.

You, Emma, for example, speak of living in a kind of silent fear since Donald Trump took office, even though you were born in this country and your parents are here legally. You are right, “We shouldn’t have to live in fear that our rights will be taken away.”

And Aminata, you write of being constantly judged and labeled because you’re a Muslim American. How unfortunate and sad that in a country that generations of people fled to search for religious freedom, you are ashamed at times to practice your own. The Constitution-free zone, you write, “goes directly against the Constitution, the soul of this country, something that asserts that we are all equal before the law.”

Tiara, I could personally relate to your gripping account of being racially profiled and humiliated in a store. You were appalled that the Greyhound passenger in California was targeted by Border Patrol because they claimed his shoes looked like those of someone who had walked across the border: “If a man is judged by his shoes,” you ask, “who else and what else are getting judged in the world?”

Hailee, you write about the incorrect assumptions people make about you, an American born of Korean descent, based solely on your appearance and compared it to the assumptions Border Patrol agents make about those they detain in this zone.

Daniel, you speak of the role of political fearmongering in immigration. It’s not new, but under the current administration, turning immigrants into boogiemen for political gain is currency. You write that “For some politicians, it is easier to sell a border wall to a scared population than it is to explain the need for reformed immigration policy.”

And Ethan, you recognize the contributions immigrants make to this country through the connections we all make with them and the strength they bring to our society.

Keep speaking your truth. Use your words and status to call out injustice wherever and whenever you see it. Untold numbers of people spoke out against this practice by Border Patrol and brought pressure on Greyhound to change. In December, the company began offering passengers written guidance—in both Spanish and English—so they understand what their rights are when officers board their bus. Small steps, yes, but progress nonetheless, brought about by people just like you, speaking up for those who sometimes lack a voice to speak up for themselves.

With sincere gratitude,

Lornet Turnbull

We received many outstanding essays for the Winter 2019 Student Writing Competition. Though not every participant can win the contest, we’d like to share some excerpts that caught our eye:

After my parents argued with the woman, they told me if you can fight with fists, you prove the other person’s point, but when you fight with the power of your words, you can have a much bigger impact. I also learned that I should never be ashamed of where I am from. —Fernando Flores, The East Harlem School, New York City, N.Y.

Just because we were born here and are privileged to the freedom of our country, we do not have the right to deprive others of a chance at success. —Avalyn Cox, Brier Terrace Middle School, Brier, Wash.

Maybe, rather than a wall, a better solution to our immigration problem would be a bridge. —Sean Dwyer, Lane Community College, Eugene, Ore.

If anything, what I’ve learned is that I don’t know what to do. I don’t know how to change our world. I don’t know how to make a difference, how to make my voice heard. But I have learned the importance of one word, a simple two-letter word that’s taught to the youngest of us, a word we all know but never recognize: the significance of ‘we.’ —Enna Chiu, Highland Park High School, Highland Park, N.J.

Not to say the Border Patrol should not have authorization to search people within the border, but I am saying it should be near the border, more like one mile, not 100. —Cooper Tarbuck, Maranacook Middle School, Manchester, Maine.

My caramel color, my feminism, my Spanish and English language, my Mexican culture, and my young Latina self gives me the confidence to believe in myself, but it can also teach others that making wrong assumptions about someone because of their skin color, identity, culture, looks or gender can make them look and be weaker. —Ana Hernandez, The East Harlem School, New York City, N.Y.

We don’t need to change who we are to fit these stereotypes like someone going on a diet to fit into a new pair of pants. —Kaylee Meyers, Brier Terrace Middle School, Brier, Wash.

If a human being with no criminal background whatsoever has trouble entering the country because of the way he or she dresses or speaks, border protection degenerates into arbitrariness. —Jonas Schumacher, Heidelberg University of Education, Heidelberg, Germany

I believe that you should be able to travel freely throughout your own country without the constant fear of needing to prove that you belong here . —MacKenzie Morgan, Lincoln Middle School, Ypsilanti, Mich.

America is known as “the Land of Opportunity,” but this label is quickly disappearing. If we keep stopping those striving for a better life, then what will become of this country? —Ennyn Chiu, Highland Park Middle School, Highland Park, N.J.

The fact that two-thirds of the people in the U.S. are living in an area called the “Constitution-free zone” is appalling. Our Constitution was made to protect our rights as citizens, no matter where we are in the country. These systems that we are using to “secure” our country are failing, and we need to find a way to change them. —Isis Liaw, Brier Terrace Middle School, Brier, Wash.

I won’t let anyone, especially a man, tell me what I can do, because I am a strong Latina. I will represent where I come from, and I am proud to be Mexican. I will show others that looks can be deceiving. I will show others that even the weakest animal, a beautiful butterfly, is tough, and it will cross any border, no matter how challenging the journey may be. —Brittany Leal, The East Harlem School, New York City, N.Y.

Global Refuge Staff

July 14, 2021

Immigration — and its dynamic effect on global development — has been the subject of many reports, studies, and debates. Its economic implications have shaped global industries for years and are changing the world for the better.

Global migration is a large-scale topic. Currently, there are an estimated 272 million international migrants, which account for 3.5% of the world’s population. While the percentage may seem relatively low, the number of migrants already surpasses some projections for 2050.

In a 2020 report by United Nations (UN), it was revealed that one in every 30 people is an international migrant. Europe and Asia alone host around 82 to 84 million immigrants.  These regions were followed by North America, which houses almost 52 million international migrants.

Every year, the percentage of international citizens traversing borders increases and drastically impacts a country’s population size, cultural diversity, and economic productivity.

With the constant wave of settlers and refugees around the world today, a significant question arises — what exactly are the causes of immigration?

The Roots of Immigration

Immigration, in its simplest definition, is the movement of people from one place or country into another one. It is a simple yet fundamental aspect of human history.

Immigration is a concept that pre-dates existing laws. Long ago, nomadic tribes traveled from place to place to find fresh and fertile lands, pastures for their livestock, and rich areas for hunting and fishing.

In modern times, immigration still continues all over the world. In the past decade , the demographic composition of people traversing borders has significantly changed. This can be attributed to a wide range of factors that we can categorize into two groups — push and pull factors.

It is essential to examine these factors in order to perfectly understand the increase of global migration throughout the years.

Push and Pull Factors

To reach well-developed immigration and foreign policy solutions, it is important to recognize the driving factors that prompt individuals to migrate.

People around the globe immigrate for a wide array of reasons that we conceptualize as “push” and “pull” factors.

Push factors are reasons that compel or push people to leave the area of where they reside and settle someplace else. Common factors can include armed conflict, disaster exposure, gender inequality, lack of job opportunities, political corruption, and lack of access to competent healthcare and education. In simple terms, push factors are negative reasons that prompt individuals to leave.

Pull factors are, on the other hand, the exact opposite of push factors. They attract or pull people to move and settle in a particular area. Common pull factors may include better work opportunities, greater security, and access to adequate healthcare and education. Simply put, pull factors are positive reasons that prompt individuals to move.

Immigration, however, is not as simple as being pulled and pushed for merely a few reasons. The push and pull framework is a combination of factors that encourage a person to leave a place of origin and factors that draw a person to a destination.

Push and pull factors are never the same for everyone, and the reasons for immigration are unique to each individual.

However, even though factors can change depending on age, gender, health, social class, and ethnicity, a push or pull factor may describe a pattern that can be attributed to many different reasons.

Quality of Life Factors

Conditions that influence an individual’s quality of life vary from person to person, but may be the leading factors leading to immigration. These can include labor standards, poverty, and the overall state of a country to provide a quality life.

In most cases, people are pulled by work opportunities in a certain area which aren’t available in their place of origin. Data analysis has even shown that there is an increase in the immigrant’s quality of life due to migration that is reflected in financial status and job satisfaction.

People from places like Syria (which has a high unemployment rate of 50%) often immigrate to escape poverty and lack of work opportunities. Numerous developed countries, including the United States, provide a network or social platform that proves to be advantageous for people hailing from less developed countries.

Immigrant workers (people who migrate to pursue work) represent nearly two-thirds of the international migrants in 2017 — standing at roughly 164 million worldwide.

Another large factor involving an individual’s quality of life is access to a proper education and to medical services that are otherwise inaccessible in their country.

War-Torn Country Factors

A major socio-political factor pushing individuals to leave their place of origin is the presence of war and conflict.

Oppression because of one’s ethnicity, religion, gender, race, and culture poses a significant risk to quality of life, which increases the odds of an individual settling elsewhere.

People fleeing conflict zones, human rights violations, and government persecution are asylum seekers that desire international protection and a safer region. Individuals who are forcibly displaced because of external factors, such as war, are refugees.

In recent times, a large number of people have fled to Europe to escape conflict, persecution, and terror in their homeland. Over a quarter of asylum seekers from Syria were granted protection status, with those from Afghanistan and Iraq following respectively.

Environmental Factors

Natural disasters and climate change are environmental factors that disproportionately affect impoverished families, especially in less developed countries.

Individuals that experience regular occurrences of floods, hurricanes, and earthquakes are most likely to immigrate. Additionally, climate change is expected to worsen weather events, leading to an increase in immigration flow.

Environmental immigrants are obliged to leave their point of origin, be it temporarily or permanently, and either move within their country or abroad to avoid the adversities of nature.

According to the United Nations Environment Programme ’s statement on climate change and immigration, these are the three environmental factors that can affect immigration in a significant way:

  • Effects of Warming: Constant warming in certain areas will slowly bring down agricultural productivity which may lead to a lack of fertile soil and clean water.
  • Increase in Extreme Weather Events: Extreme weather events caused by the change in climate, such as violent storms and resulting flash floods, may displace millions of people.
  • Rising of Sea Level: The constant sea level rise poses an extreme environmental danger to low-lying coastal areas and may result in the permanent displacement of more than a million individuals.

Why Do People Immigrate to the US?

According to the UN’s World Migration Report of 2020 , the United States of America has been the primary destination for foreign migrants since 1970.

In less than 50 years, the number of foreign-born residents of the country has more than quadrupled — from less than 12 million to close to 51 million.

The reasons why so many people immigrate to the US have changed throughout the years, but the country’s core pull factors are what make it the leading destination for immigration.

The United States ranks as one of the most desirable countries to immigrate to because of the better living conditions provided.

The country has an active economy with a wide array of work opportunities for everyone. Wages are higher than most countries, with a relatively low cost of living. Individuals coming from a more collective society prefer American individualistic values.

People that are employed in the United States who have long-distance families are great examples of what compels families to immigrate. When these people gain their green cards, they want their children to move from their native country to the United States to be with them.

Moreover, the United States has access to healthcare and quality education that is not available in many countries.

The Impacts of Immigration

As the number of immigrants increases by the year, the patterns and factors involved become harder to analyze and evaluate. With the dynamic change and demands that immigration brings, it is important to take note of its impacts.

So what exactly are the causes and effects of immigration?

  • Economic Output Growth: Net immigration can lead to an increase in the labor force and productive capacity of the economy. When this happens, there is an increase in living standards with a decline in the dependency ratio . Immigration leads to stronger economic growth and, as a result, higher tax revenues, allowing for more national spending options.
  • Better Workforce: Because of immigration, the economy of certain countries, like the UK , attracts highly skilled professionals that fill job vacancies, which contributes even more to higher tax revenues. This is due to the fact that immigrants are more likely to have higher educational and skill levels.
  • A Flexible Labor Market: Immigrants move to economies when the wages are high, which increases labor demands. The immigrants’ high mobility keeps a booming economy from overheating by providing labor to meet expanding demand.
  • Filling In for Undesirable Job Opportunities: Due to low earnings or the lack of prestige associated with some positions, native-born individuals have a tough time filling them. Businesses and employers who rely on flexible labor to fill job vacancies profit from immigration. Furthermore, when low-skilled positions are filled by migrants, native-born people can seek higher-skilled work elsewhere.

A growing scarcity of workers is widely acknowledged as one of the world’s most critically significant barriers to sustained economic growth amidst increasingly tight labor markets.

Immigration, without fail, is the reason behind the development and prosperity of most businesses and fills the increasing shortage of workers in labor markets.

There are numerous drivers behind an individual’s immigration, and such a complex process needs good research, political will, and most importantly, collective action from the citizens.

Immigrants are breathing new life into rural and urban communities, shaping labor markets, and building a dynamic society — all of which begins with a simple “push” and “pull”.

essay about causes and effects of immigration

The Causes and Effects of International Migrations: Evidence from OECD Countries 1980-2005

This paper contains three important contributions to the literature on international migrations. First, it compiles a new dataset on migration flows (and stocks) and on immigration laws for 14 OECD destination countries and 74 sending countries for each year over the period 1980-2005. Second, it extends the empirical model of migration choice across multiple destinations, developed by Grogger and Hanson (2008), by allowing for unobserved individual heterogeneity between migrants and non-migrants. We use the model to derive a pseudo-gravity empirical specification of the economic and legal determinants of international migration. Our estimates clearly show that bilateral migration flows are increasing in the income per capita gap between origin and destination. We also find that bilateral flows decrease when destination countries adopt stricter immigration laws. Third, we estimate the impact of immigration flows on employment, investment and productivity in the receiving OECD countries using as instruments the "push" factors in the gravity equation. Specifically, we use the characteristics of the sending countries that affect migration and their changes over time, interacted with bilateral migration costs. We find that immigration increases employment, with no evidence of crowding-out of natives, and that investment responds rapidly and vigorously. The inflow of immigrants does not seem to reduce capital intensity nor total factor productivity in the short-run or in the long run. These results imply that immigration increases the total GDP of the receiving country in the short-run one-for-one, without affecting average wages and average income per person.

We are thankful to Greg Wright and Tommaso Colussi for excellent research assistance. Peri gratefully acknowledges generous funding from the John D. and Catherine T. MacArthur Foundation.

Exploring migration causes: why people migrate

People migrate for many reasons, ranging from security, demography and human rights to poverty and climate change. Find out more.

The total number of non-EU citizens residing within the EU as of 1 January 2021 was 23.7 million, according to Eurostat, the EU’s statistical office. This represents 5.3% of the EU population. In most EU countries, the majority of non-nationals were from outside the EU.

What is migration?

Migration is the movement of people from one place to another, to settle in a new location. Migration can be voluntary or involuntary and can occur for a variety of different reasons, including economic, environmental and social issues.

Reasons for migration: push and pull factors

Push factors are the reasons people leave a country. Pull factors are the reason they move to a particular country. There are three major push and pull factors.

Social and political factors

Persecution because of one's ethnicity, religion, race, politics or culture can push people to leave their country. A major factor is war, conflict, government persecution or there being a significant risk of them. Those fleeing armed conflict, human rights violations or persecution are more likely to be humanitarian refugees. This will affect where they settle as some countries have more liberal approaches to humanitarian migrants than others. In the first instance, these people are likely to move to the nearest safe country that accepts asylum seekers.

The backbone of international humanitarian law is the Geneva Conventions , which regulate the conduct of armed conflict and seek to limit its effects.

In recent years, people have been fleeing to Europe in large numbers from conflict, terror and persecution at home. Of the 384,245 asylum seekers granted protection status in the EU in 2022, more than a quarter came from war-torn Syria, with Afghanistan and Venezuela in second and third place respectively.

Demographic and economic causes

Demographic change determines how people move and migrate. A growing or shrinking, aging or youthful population has an impact on economic growth and employment opportunities in the countries of origin or migration policies in the destination countries.

Demographic and economic migration is related to poor labour standards, high unemployment and the overall health of a country’s’ economy. Pull factors include higher wages, better employment opportunities, a higher standard of living and educational opportunities. If economic conditions are not favourable and appear to be at risk of declining further, a greater number of people will probably migrate to countries with a better outlook.

According to the UN International Labour Organization, migrant workers - defined as people who migrate with a view to being employed - stood at roughly 169 million worldwide in 2019 and represented more than two thirds of international migrants. More than two-thirds of all migrant workers were concentrated in high-income countries.

Environmental and climate migration

The environment has always been a driver of migration, as people flee natural disasters, such as floods, hurricanes and earthquakes. However, climate change is expected to exacerbate extreme weather events, meaning more people could be on the move.

According to the International Organization for Migration , "Environmental migrants are those who for reason of sudden or progressive changes in the environment that adversely affect their lives or living conditions, are obliged to leave their habitual homes, either temporarily or permanently, and who move either within their country or abroad."

It is hard to estimate how many environmental migrants there are globally due to factors such as population growth, poverty, governance, human security and conflict, which have an impact. Estimates vary from 25 million to one billion by the year 2050.

How is the EU addressing these causes?

Migrant workers having easier access to legal ways to move to the eu.

The European Union has been encouraging legal migration to address labour shortages, fill skill gaps and boost economic growth. These include:

  • The EU Blue Card: a work and residency permit that allows non-EU citizens to work and live in an EU country, provided they have a degree or equivalent qualification and a job offer that meets a minimum salary threshold
  • The Single Permit: a combined work and residency permit, issued for up to two years by an EU country
  • EU long-term resident status: allows people from outside the EU to stay, work and move freely in the EU for an indefinite period
  • Read more about legal ways to work in the EU

New Pact on Migration and Asylum

Managing migration effectively to deal with asylum seekers and protect external borders has been an EU priority for many years. The EU has been working on a New Pact on Migration and Asylum , and in April 2024 Parliament backed an agreement with the Counci to revamp the EU’s asylum and migration laws.

The pact sets out improved and faster procedures throughout the EU’s asylum and migration system. It revises the Dublin regulation, which determines the country responsible for processing each asylum claim. The new system sets different types of contributions from EU countries, including the relocation of asylum seekers from the country of first entry, financial contributions or providing operational and technical support. The new system is based on solidarity and flexible forms of support, which could become requirements at times of pressure .

Once the new rules come into force, EU countries will have two years to incorporate them into their national laws.
