It would be unjust to aspiring legal immigrants to allow those here illegally to be given legal status without first returning to their home countries.
I also love how the amnesty people keep saying the illegals will go to the "back of the line." I don't know how they get away with such BS. The line to get a greencard is over 20 years long in most places, yet under Bush's plan, the amnestied illegals get green cards in just SIX YEARS. And not only that, they get to say here while waiting!!! The poor saps who played by the rules have to stay at home.
Back of the line my arse.
