Actually they are not.
In most places it's illegal for them to be in the country but it's not illegal for them to work, rent an apartment, pay taxes etc.
Look at all the laws that have been shot down recently concerning this very subject.
Gee, your new gig doesn't involve hiring illegal aliens does it? Such moral behavior....
Could you please do all of us a favor and let us know who it is you support for president in 2008? I really want to make sure I cast my vote correctly and I'd hate to waste it on someone like, say, Rudy who looks at things the way you do. Voting is very much a right in this here republic, you will find it in the constitution. The cool thing is that I get to vote and these illegal aliens don't, at least for now. So, please, let us know.
You have no idea what you talking about. If they are in the country illegally, then they can't legally work in any job.
