Oh, so boo-hoo you don't want them to have to wait like everyone else? Why? Why should Mexicans get expedited US citizenship over anyone else?
The line is the line. Whether you are Mexican, Canadian, Russian, Chinese, whatever - get in line. No one should get to go around to the front.
I don't mind illegal aliens getting in the back of the line - no one should be waiting 28 years for U.S. citizenship though.
