it *MAY* be possible to cancel your extension of stay based on studying in CM and then fly back to Bangkok, but I don’t think it is possible logistically. You will have to (all in the same day):
1. Fly to CM
2. Get the documents from your school saying you are no longer studying
3. Cancel your current extension of stay based on studying
4. Fly back to Bangkok
5. Go to Bangkok immigration and file for a 60 day extension of stay based on unable to travel due to COVID-19.
The first flight from Bangkok to CM is at 6:10am, and you’ll get there by 7:30. There is a flight from CM to BKK that leaves at 10:30am, and you’ll arrive at BKK at 11:35.
You’ll be cutting it really close in CM.
