Introduction The question of the immigration and its influence on different spheres of life in different countries is being discussed for many years. This paper’s aim is to show the influence of illegal immigration on U.S. economics and labor market. I will discuss, whether the illegal immigration has good influence or bad and how it increases competitiveness on the labor market between native workers and immigrants on the basis of scientific articles of different scholars. For many years the whole world discusses how immigration influences an economics of different states. There are so many opinions concerning this question: some think that it increases competitiveness between native workers and immigrants and pushes native unemployed potential workers to study harder and then to try harder in order to find a job. Native Americans usually do not want to employ for a secondary labor market job, because it is low paid and there it is usually to be a very hard work. However, illegal immigrants usually seek for a job like this, because it does not require much skills and high educational level and on the contrast it might generate a not bad income. By the way, immigration’s influence on local labor markets is surprisingly small, even on the secondary labor market (Ender, 2005). Others claim that countries spend just huge amount of money every year on illegal immigrants and does not have anything from them, because they do not pay taxes. There are also different programs which allow immigrants and their children to receive different subsidies from state. For instance, in Santa Ana, CA there is a program which allows every of 55,000 students in a school district to receive a free breakfast and lunch whether a student qualifies for it. It is $39.6 million each year at $2 per meal for mostly Hispanic children (Kirkwood, 2010). Main Body There is a huge demand on hard-workers in the U.S., especially at different farms and households.
