Is it safe to leave my passport with a school while awaiting my education visa in Thailand, given my visa exemption is about to expire?

I did 3 ED visa in a row with the same school in Phuket (Patong) and they handled the whole procedure every time and took and kept my passport until I got my visa each time. Then later, I would go to the immigration with a school representative cause a visa is something personal and they need to actually see you for it.

So I would say yes, it's normal. Your ED visa has to go in your passport and that's the school that's handling the whole procedure with the immigration.after getting a letter from the ministry of education. So how would the school obtain your visa if they don't take your passport until it's done ?

The whole process between the school, the ministry of education and the immigration takes about 3 weeks.

I suppose you gave your passport to the school something like 3 weeks or more before your visa exemption expired, right? So IN THIS CASE, once the procedure is on track, you don't have to worry about your previous expiring date.

Don't hesitate to contact me back for more details, if needed.
