Exactly. He needed a student visa and the rest of the Harvard’s students who are from other countries are expected to have the appropriate visa paperwork or would not be allowed to enroll. So the guy basically broke the university’s rules just as much as the recent student who was a complete fraud and was attending Harvard.
I am at an Ivy League university and I have had grad students miss their acceptances/enrollments because their student visa’s were finalized too late (not even that they were not eligible and getting a visa, just that it was too late).
As I have posted previously, he was not eligible to obtain a student visa....his problem is unfixable if he wants to remain in the U.S. I understand the "kick him out" sentiment...but don't try and pretend he was just to lazy to "fix the problem".
