Andrew Ely, then you had a non imm O-A based on retirement I guess. Because a non imm O based on retirement, without the A, is also 90 days max. in country.
, don't want to hijack this post, but is the extension stamp for e.g. 30 days, different from the 60 day 'covid extension' ? I mean besides the 60 days given to the OP ? I know it depends a bit of the imm office you have to go if they want you to do a regular 30 days extension first or one gives the 60 days 'covid extension' right away and sometimes a 'under consideration' first given. 'under consideration' you can see clearly, but I'm not aware of differences in extension stamps. What I see, my year extension stamp, looks the same. Thanks !!!
. In Thailand you got an extension of stay for 1 year I guess. Maybe on a visa Non imm OA or Non imm O originaly ? THEN it is not multy entry and you have to buy one as mentioned above...
Isn't it a possibility to get a non imm O single entry on base retirement in y'r country ? Then you have 90 days and after the quarantaine, open a Thai bank account and transfer 800k฿ in it. I know it's a bit hard to get a Thai bank account, but with y'r girlfriend (still no wife then), it should be possible at a Kasikorn- or Bangkok bank branch, If you reserve one day going from branch to branch. When the 800k฿ is in (after 2 months in), you can then go for a 1 year extension of stay based on retirement. Of course if you managed to be legaly married when asking a year extension based on marriage, then you need the 400k฿ in place. Just a thought ?
