I would suggest that any guest-worker plan begin with the names that are at the top of the current list, long backlogged, I'm sure, of those foreign nationals who have been patiently waiting their turn in line to get in to work in the U.S.
As a matter of fact this is one of the arguments against a blank amnesty plan which I am OPPOSED TO,... that you are rewarding the ones who broke the law... and penalize those who waited, or have been waiting patiently for years through legal channels.
Guess what, this will not be easy to solve... but it must be solved somehow.
