Approx how long does it take to obtain a re-entry stamp at Suvannabhumi ? Need to budget airport time. Tried at the Jomethein immig office, and after 2 hr of queue time, was told I need a print out of an outbound flight (which doesn't make sense ), tm30, 90 notification copies.. etc. Rather not return to Jomethien immg. I already have the TM8 filled and can perhaps reuse at the airport.
