Reply #2: Not unrestricted, but I think non-Americans could be given

work permits. If they manage to stay employed for five years then give them a Green Card and a chance to become American Citizens. I would insist that prospective employers do their hiring in Mexico or whatever country that they are recruiting in and then apply for the permits from the American Consulate, although an agent could act in the employers behalf.

They should also be required to pay for the worker's transportation to the job and back to their country when the job is through. Also, they need to follow the law as far as meeting minimum wage and employee safety is concerned and of course pay American taxes.
