Well Brandon talks about the non imm. O (Single entry) WITHIN the 90 days. What I understand from the non imm. O multi entry (1 year valid and with every border bounce you get 90 days again) does not exist anymore from the time it has to be asked on the Thai imm. internet site.
Umm, not sure, but doesn't he meen a Thai visa getting in Vientiane ? Don't know if he needs a tourist visa instead of 60 days exempt entry đ¤ˇââī¸ Also a bit tricky on his page he says living in BKK đŦ
There is no tourist visa for 3 months. Valid for 3 months but when you enter Thailand, you can stay 60 days. After that you can get 30 days extension at an Imm. office for 1,900ā¸ŋ.
Thaiembassy.com is not a site from a Thai Embassy. Also no date. And last but not least, you have nothing to do with the Thai Embassy, you have to do with Thai Immigration.
Maybe I overlooked but which imm office you try to apply now ? Then phone a nearby imm. office if they do the "in country non imm. O". Maybe you get answers here for that nearby office or also ask in other groups like
