I'm a US Citizen and withdrawing from my studies this week. I understand my study permit is valid for another 90 days. Since I'm visa excempt do I still need to apply for a TRV to stay here after the 90 days? If so, should I apply right away or wait to the end of the 90 days? Is there a different process for switching status or you just start with a fresh application? If the border does open in the next couple months is it possible to just do a quick trip across the border and come back on visitor status? (this one I'm counting as a 1% possibility)
