ThaiApec

Currently I am in Thailand with a 90 days APEC entry visa which is about to expire. Does anyone know how I can extend my stay for an additional 30 or 60 days without leaving the country ? I heard it's possible to get a 30 days extension ??? How ??? Is it necessary to get a letter from my Embassy before going to the immigration? If so , what should be the content of the letter ? Many thanks in advance !

Hi T, I got the same problem as you guys now (in 2022) ... are you saying that the Immigration could give you first a 30 days extension without any letter from your Embassy (after your 90 days APEC visa entry) ... and the letter of your Embassy is needed only if you want to stay longer than 30 days ? In that case; what kind of letter (letter content) should the Embassy issue for you ? Thanks for your clarification.
