It can may Mexico a separate issue, but will likely violate international agreements if it does.
But Mexico is a different cat to skin, and I believe that because of the illegality of the worker, this issue can be handled differently from normal ex-pat rules and regs.
I think it should.
Not because I am anti-illegal. I am a backer of Bush's worker plan, however I believe this issue could be part of the negotiations on the coming agreement. When and if it occurs.
