The Free can come & go as they please. It's the Illegals who won't. Do you have a problem with adherence to Federal law?
Not with adherence to the law, but I do have a problem with a policy that makes America look mean-spirited, selfish, short-sighted, and rather vicious. At the very least, cracking down on those who illegally employ the illegal immigrants would accomplish the same purpose without the Auschwitz overtones.
