Information Only, after reading about Re-entry Permits in Bangkok I decided to go to Suvarnabhumi to buy mine before I leave next month.
I chose BKK because transportation is easier than the other offices for me.
I got all the way here to find out that you can ONLY get 1 the day you fly out. Unfortunately that was not mentioned on anyone of the 3 sites I read.
I guess I could have asked here but it seemed to trivial to bother when I thought I could read for myself.
Again FYI.
