They should kick them both and their kids out. Seize the assets held here. Question the employers, loan officers for their house and cars, and fine those businesses in violation to lending or employing an illegal.
What I don't understand is you can recieve a fine up to $250,000 and up to x amount of time in jail for copying a movie with George Clooney in it. Or you can goto jail for selling booze to a minor. But no severe consequences for businesses who employ illegals that cost us billions? I think the problem would possibly solve itself if the govt imposed some hellacious fines for each illegal employed and jail time for employers. Have a national database of legal workforce (Social Security, Dept of labor) where once a potential employee checks out your safe from penalty. If empoyees don't check out notify the INS for interview and possible deportation.
