That's never been the definition of amnesty in the past. For example, the Reagan amnesty didn't do that.
The worker plan, as I understand it, requires the employer to contract with specific migrant workers for a specific job for a specific period of time.
Generally, yes, that's how a guest worker program should work, but the rub is in the details. Tancredo's proposal operates on that principle for legitimate migrants without legalizing any illegal aliens. The Bush proposal legalizes illegal aliens who've been working illegally, and gives them an advantage over guest worker applicants who've followed the rules and aren't yet matched with a prospective employer.
"the Reagan amnesty didn't do that"
Really ..?? Then what did it do ..??
