You're right that there are probably millions of illegals who are hard workers, nice guys, etc.
But that's missing the point.
As one who walked with a spouse from overseas marriage right through to the citizenship ceremoney, I can tell you a little bit about the immigration process.
Foremost, there currently are 1.5 million backlogged legal applications in the immgration system, and the number is actually higher, since CIS has recently been playing some transparent numbers games to "clear the backlog" (e.g., when the backlogged apps from a country exceed that country's annual quota, the excess apps are simply lopped off the "backlog" count).
In any case, it is egregiously unfair to law-abiding applicants to insert 10 to 15 million "guest worker" or other apps into a system that's currently overwhelmed merely by legal apps.
In fact it's unfair and I think immoral to insert even one application from an illegal alien in front of anyone who's waited years to go through the legal immigration process.
Thank you Angkor. My wife immigrated from China,legally. It took about 10 years. She acquired her green card, started working one week after arriving, learned to speak English and never asked the gov't for a penny. All she wanted was a chance. She now runs a business from home, with a little help from me, and is about to take a real estate license test. It is an insult and a slap in the face of all who immigrated legally. I would like to hear the chronic loser explain to her why illegals, who are breaking the law, should be allowed to stay without going through the same process she did. Then I would like to watch her wipe the floor with the chronic loser. My wife is on the small side but she is a chiwauwa-pitbull when she is pissed.
