I think there's lots of ways to stop that from happening. For example, giving a green card to people who graduate with certain degrees like Engineering/Science or MBA's from top schools (yes its snobbish but whatever ... a degree from the University of Phoenix shouldn't get you a green card) As well as allowing students in particular programs to work while they go to college.
