This thesis paper researches the impact of illegal immigration on U.S. social services. The study focuses on information gathered from a group of illegal Mexican immigrants who have lived and worked in the U.S. The sample of illegal Mexican immigrants was attracted to the U.S. primarily for economic reasons. The U.S. economic system has directly and indirectly attracted Mexican workers into America for over a 100 years. The U.S. economy has directly attracted Mexican workers through recruitment practices employed by several U.S. business sectors. Indirectly, the powerful U.S. economy has historically attracted Mexicans north because the U.S.'s economy offers more economic opportunities than the Mexican economy. Illegal Mexican immigrants' presence in the U.S. economy has led to the increased use of U.S. social services and as a result of this extra use, a burden has been put on several social service institutions. To what extent this burden affects the U.S. economy is still not clear because illegal immigrants pay U.S. taxes that may compensate the system for this extra use
