This definitely doesn’t make sense to me. Time zones are going to be a huge issue. If a coworker told me they were going to work from an asian/european timezone, we could try to make it work, but it’s definitely a hassle. The story is no different for universities and their courses.

Please explain your plan for what happens the following semester, once in-person classes resume, and these students are stuck abroad until such time that they are able to renew their visa stamps (which is a notoriously expensive, long process that can result in denials for completely arbitrary reasons).
