I find it amazing that Dan Rodricks and others who support illegal immigrants always mix up legal and illegal aliens ("Immigrants: We detest them — and need them," June 30). An undocumented alien is an unlawful intruder into this country. Seasonal migrant workers on H-2B visas are documented workers and thus legal immigrants.

Illegal immigrants in the U.S. are an affront to all immigrants who followed the process, paid their money and waited their turn to arrive in this country.

Illegal immigrants going to college is a waste of taxpayer money anyway since they can't legally be employed. Every illegal immigrant in college is stealing a seat from citizen students and legal immigrants.
