Schools should update their information in the Student and Exchange Visitor Information System (SEVIS) within 10 days of the change if they begin the fall semester with in-person classes but are later required to switch to only online classes, or a student changes their course selections, and as a result, ends up taking an entirely online course load. Many schools including Harvard have announced that they are working on changing their schedule to make sure that their students are not affected and can safely stay in the USA.
