Hi all, 

if you have a single Non o visa, I understand that you can pay a B1000 in advance to renter Thailand if you leave the country. Is this the case or is only with a multiple entry Non O visa

You can get a re-entry permit to keep the remainder of the 90 day entry from a single entry non-o visa valid when you enter the country using it. The fee is 1000 baht for a single re-entry permit. The re-entry permit adds no days to your stay since it will expire on the date the 90 day entry ends.

If you had a multiple entry non-o visa you would not need a re-entry permit unless you were on the last entry after it expired.

As I thought. 

Thanks again Ubonjoe
