They came here legally, perhaps, but overstayed their visas. They sure took advantage of our disfunctional system. We have 3.1 million visa overstays "somewhere". Everyday we hear of a green card holder who commits a crime. This government can't handle the situation now and you are willing to allow another 15 to 20 million become "guest workers"?
Remember now, these new guest workers are "undocumented", right? That means they'll apply for their amnesty (er...guest worker)with NO documents. Just pick a name! THAT will be the name this government will issue a visa to. What a way for a criminal to gain a new identity with all the priveleges of a "guest worker". Many municipalties allow them to vote, get welfare.
What a country!
Salient and often overlooked logic ping!
