Illegal immigrants: what do you think?

I have such mixed feelings. My daughter went to high school with an illegal girl from Mexico. The kids were very protective of her: it was hard for me knowing I was paying $8000 a year for my daughter to go there, while she was probably getting lots of help. Now she’s in a state university with the help of a teacher…
America is made up of immigrants; yet do we continue to support them? I woner what the collective thinks/feels?
