Has anyone successfully used the re-entry visa service which I believe may be available at Suvarnabhumi and Chiang Mai airports and is it manned 24/7 or just whenever ?

 

Cheers.

Moved to Thai visas forum where similar questions are answered repeatedly.

 

The re-entry permit desk is open 24/7 at Suvarnabhumi. It is located after security at departure Immigration zone 2.

The re-entry permit desk in Chiang Mai is open when there are international flights departing.

Many thanks Ubonjoe - most helpful.

As Ubonjoe said, Chiangmai re-entry desk is always open if there is an international flight leaving.  Once you go upstairs and go through the passengers-only entry, the counter is on the left.  Of course, make sure you have your documents and photo (I have no clue if they can take your photo there but I doubt it).  Documents needed in CM:  TM 8 completed (print your telephone number and address somewhere near your signature), photo,  passport pages all signed (photo/name page, current visa/extension, entry stamp page, and TM6/Departure card). Typically takes about 5-7 minutes in CM.

Thanks Bob - very useful info.
