The only group that they have relatively good monitoring system is the international students who go to legitimate schools, through SEVIS. Students have to take certain number of credits to stay legally in the US. Even this, the problem will only arise when the students want to officially depart from, or re-enter the US. Apart from this system, I don't know how they trace 'visitors' -- especially those who do not want to take official routes.

9/11 showed the failure of the student visa program and wouldn’t be shocked if it was still not fixed. When they drop out of school no one was tracking them. After the OU ‘lone suicide bomber’ case, it doesn’t look like they are still tracked if they drop out of school.

Has to be a better way because the current way is a farce.
