Illegal immigration is regarded as a contradicting topic in the United States. More and more newcomers enter the county illegally in an attempt to apply for a prestigious job. However, in case the government allows to undocumented workers to gain permanent residents, it can lead to unpredictable outcomes. The majority of unofficial U.S. citizens continue settling around the country. However, the U.S. government fails to recognize the potential threats of these tendencies, as well as predict how it can influence the future economic infrastructure. In fact, the reason of mass immigration to the United States is explained by a recognized view that the country is a land of hope for building better future. Therefore, it is a desirable destination for the immigrants from the developing economies. There are various reasons for immigrants from Mexico to arrive in the country, including economic and political ones. In particular, they come for economic purposes, as well as for reuniting with their family residing in the United States. With regard to the above-presented circumstances, the economic reasons for illegal immigration are the most tangible ones. Despite the illegal issues, the U.S. government still encourages employers to hire undocumented workers due to the global economic change and inefficient employer sanctions. The global economic change, therefore, constitutes the main underpinning for illegal immigration due to the advancement of information technologies, as well as to the internationalized distribution, consumption, and production. Finally, the economic challenge of illegal immigration also undermines the educational system in the United States. Illegal immigration in the United States has become the urgent issue on the economic agenda. On the one hand, the phenomenon has positive economic effects for both the employees seeking the cheap labor and for the American government that realizes the actual contribution this segment makes to the U.S. economy. On the other hand, the active flow of illegal immigrants negatively influences the situation with unskilled workers, the segment that lacks sufficient technical training and education. Therefore, the U.S. government acknowledges the fact that they can benefit from a small amount of illegal immigrants coming to the United States, which should not exceed 1 % of the total employees. However, much greater ratios of illegal workers can pose a serious threat to the Americans and provide a new challenge for the employment sphere. As it has been mentioned before, the illegal immigration in the Unites States creates both opportunities and shortcomings for the economic development. Integrating a new segment of employees can decrease the wages of unskilled and low-skilled workers. However, paying lower wages constitutes the only benefit for the American economy. Moreover, government expenditures on the undocumented employees are much higher than on residents because the illegal population does not have to pay taxes. In addition, the employees do not take advantage over public services and other governmental institutions. Apart from these effects, there are also much more serious consequences for encouraging illegal immigration in
