Hi, just confirming that if you enter (for the first time) via airplane on a visa waiver 30 days, you don't need TM6 for the 30 day extension?
TLDR : Answer Summary
If you enter Thailand by air on a visa waiver for the first time, you do not need a TM6 form for a 30-day extension, as TM6 cards have been suspended for air arrivals. However, the TM6 form is still required for those entering through land borders.
