The bigger issue here is that schools have never been good about filtering out those who actually belong in a university from those who do not. They don’t really have an incentive to, because more students is more money. That’s a problem not just for internationals, but for nationals as well. Those that have no place in a university shouldn’t be allowed to go there in the first place. That’s just playing fast and loose with other people’s money - the student’s, federal loan money, and state subsidies for in-state students.
