For those of you who are under the misguided impression that all illegal immigrants "sponge" off of the U.S. Welfare system, please read some of the following reports:
The Reason Foundation
The Washington Post
The New York Times
The truth is, many illegal immigrants do pay taxes, but are not entitled to many of the benefits those taxes pay for. As for free college tuition, that would only be possible through scholarships payed for by private donors, illegal immigrants are not entitled to receive public money for a college education.
