Noob question. METV - the 60 days can't be extended within Thailand at Immigration like an SETV can it? You need to leave the country every 60 days I think? Also do you have to fill out a re-entry form? Is this done on the way out? And lastly - can you just border bounce in and out or do you have to stay out for 24 hrs? The guys at the consulate didn't really explain!
TLDR : Answer Summary
A Multiple Entry Tourist Visa (METV) allows you to stay in Thailand for 60 days per entry, which can be extended for another 30 days at local immigration for a fee of 1900 baht. You have the option to border bounce to obtain a new 60-day stamp, and there are no specified rules about the duration you must stay outside Thailand before returning. You do not need to fill out a re-entry form when leaving Thailand.
