I don't pretend Trump even knew or did anything directly to make this the case. I know immigration has gotten harder for some but until we know the full facts of this case, which we likely never will because the government keeps private matters private, the person could have been removed for any number of reasons. Perhaps some new information came to light, maybe a 3 letter agency notified USCIS of information that there is reason to be concerned about this student or family members. They view visas as a privilege so they'll revoke them if there's a hint of concern.

All I'm saying is without all the facts, we don't know that this wouldn't have happened under the last President either. The post-9/11 immigration policies have been rather harsh on a lot of people.

If the person is as smart as they say, there are plenty of good or better colleges they can likely go to in other countries and will be fine. It'll be our loss, not his.
