In January 2004 GWB proposed that illegals get a three-year work visa, once renewable.
The you go home, to stay there, or to apply for U.S. residency, or whatever.
Point is (and GWB did make this point), at the end of your "work visa" you go home. If you want residency, you get in line behind law-abading applicants, who in many cases have been waiting 5 or 10 years or even longer.
But somewhere in trip from January 2004 until today, GWB has suddenly found the case for a "a path to citizenship."
