Illegal Immigration in the US: Economic and Social Costs

Introduction: A Nation Built by Immigrants

The United States has a long and tumultuous relationship with immigrants from other nations. This nation was born out of the efforts of immigrants, yet today it faces a large population of undocumented residents who have strained the country's resources and tested many citizens' patience. Despite legal and governmental efforts to curb illegal immigration, data from 2006 reported that approximately ten to twelve million immigrants lived within the country illegally (Rector, 2006). A similar study conducted in 1997 identified around five million undocumented individuals in the country — a shocking increase within a single decade. With undocumented immigrants representing an average of roughly 4% of the total U.S. population, the country found itself confronting a significant policy challenge.

Although the nation has historically embraced immigrants for the diversity and vitality they bring, immigration cannot go entirely unchecked. As John F. Kennedy observed, "There is, of course, a legitimate argument for some limitation upon immigration. We no longer need settlers for virgin lands, and our economy is expanding more slowly than in the nineteenth and early twentieth centuries" (Kennedy, 1964). The rapid growth of the undocumented population raised urgent questions about resource allocation, national security, and the fairness of the immigration system itself.

Many undocumented immigrants place considerable strain on national resources through programs such as Medicaid and the costs associated with incarceration. According to figures cited by U.S. Immigration (2006), 33% of those in America's prisons are not full citizens. American tax dollars allocated to inmate care consequently cover the costs of housing undocumented individuals, at an average of approximately $31,000 annually per incarcerated person. With the American economy already under significant pressure, these costs represent an added burden on ordinary taxpayers.

Economic and Fiscal Burdens of Illegal Immigration

The fiscal impact extends well beyond incarceration. According to a study conducted by Rector (2006), the federal government spent approximately $500 billion annually on assistance costs related to this population. The Federation for American Immigration Reform (FAIR, 2003) concluded that "taxes paid by immigrants do not cover the cost of services received by them," creating further dependence on the American welfare system. The relationship between immigration and public finances remains one of the most contested dimensions of the broader policy debate.

Rising numbers of undocumented residents also affect workers in local states and cities in various ways. With the U.S. economy already weakened, many workers face job insecurity — yet millions of undocumented residents are employed within the country's borders. As one analysis noted, "if the number of jobs is fixed and immigrants occupy some jobs, there are fewer available jobs for natives" (Cato, 2008). Many undocumented workers are paid informally, without contributing payroll taxes, meaning they not only occupy positions sought by American workers but also reduce the tax revenue available to federal agencies such as the IRS.

The wage effects are particularly pronounced for lower-skilled workers. Several large companies were exposed during this period as employing thousands of undocumented workers, complicating both the question of job availability and the integrity of American labor markets. FAIR (2003) argued that "job competition by waves of illegal immigrants willing to work at substandard wages and working conditions depresses the wages of American workers, hitting hardest at minority workers and those without high school degrees." Research on labor market effects of immigration consistently identifies low-wage, low-skill sectors as the most directly affected.

One potential resolution is a dual-action approach combining tighter border control with reform of the citizenship process — making it easier for immigrants to enter the country legally rather than resorting to illegal means. Strengthening border enforcement is a prerequisite for developing a more accessible legal immigration system. With "the major source of illegal immigration from illegal border crossings, and most of these immigrants from Mexico" (Meese & Spaulding, 2006), the United States must address this primary channel of unauthorized entry. Once that risk is reduced, government officials would be better positioned to craft more accessible immigration procedures that allow greater numbers of immigrants to enter legally.

Impact on Jobs and American Workers

The national security dimension also demands attention. As Meese and Spaulding (2004) noted, "Secure borders, especially in a time of terrorist threat, are crucial to American national security." At the time of writing, proposed legislation under the Comprehensive Immigration Reform Act (CIRA, S. 2611) was looking to grant amnesty to nine to ten million undocumented individuals. If such a policy framework were adopted alongside a reformed path to legal citizenship, it could incentivize future immigrants to pursue legal channels rather than crossing borders illegally. The 2006 comprehensive immigration reform debate reflected deep disagreements over how to balance legalization with enforcement.

This approach, however, evokes a further complication — "the other source of illegal immigration from those individuals who stay in the United States after their non-immigrant visas expire" (Meese & Spaulding, 2004). Reforming the path to citizenship and expanding legal immigration options does not automatically resolve the problem of visa overstays, which constitute a significant share of the undocumented population.

Although providing a simpler and more reliable path to citizenship could reduce future unauthorized entries, current liberal legislation in its planning stages risked further draining an already strained economy. Federal reserves would face additional pressure from both the reform process itself and accompanying stricter border enforcement. While reform would create more legal employment opportunities, it would also prove costly for the government to implement. History also offers a cautionary note: previous experiences with amnesty reveal a high incidence of fraud among applicants. Following the passage of the Immigration Reform and Control Act of 1986 — sometimes referred to in connection with the Hagel-Martinez bill — approximately 2.6 million fraudulent cases were reported (Camarota, 2006). Any future amnesty program would need to grapple seriously with this precedent.
