Hi everybody.

I always requested re-entry permit at CW when I extended my permit of stay, but now I am in a situation so that I have no time to go to CW to ask for it and I must fly to Europe soon and my single re-entry permit has been used already, In the past I read that is possible to get this permit directly at Bangkok airport before leaving. Can anybody tell me if this is true and in case what is the procedure to follow? Thanks a lot

Very easy to do, check this earlier thread.

The re-entry desk at BKK is AFTER security, but BEFORE passport control. It is available 24 hours, but if you get there and don't see anyone, go ask an immigration officer and they'll find someone. Just make sure you don't go through passport control before you get your re-entry permit.

OP, correct info in above posts.

Note the permit desk is zone 2 to left of lines for passport control.

There is an optional 200b service fee where you just hand over the pp and officer does the form + pic etc
