It's one thing to not grant any new student visas because international travel and relocation is iffy right now. And it's one thing to yank visas for international students that have gone home because of the pandemic. That's understandable. But this impacts students that are already in the US, have already paid tuition for the fall semester, and are essentially shoveling free money into the country.

It makes no sense whatsoever, unless as some kind of political bullshit play around "re-opening".
