ahh get it now. If I was you I’d do some research in this group. So many people on marriage visas report how much of a nightmare it is to get an extension of stay. Non O for retirement if you qualify seems a good bet.
add to that the fact that it’s pretty much double the average income in Bangkok for a Thai. Also this is free money for the Thai Government. It’s not generated in the country so it’s adding wealth. It’s so bizzare that they make it so difficult. Although I do get the local, personal reasons haha
good luck. I’d suggest seeing if you can do the yellow housebook first. When I tried to open an account with both Kasikorn and Siam Bank both wanted yellow book. That was in the Phitsanulok/Phetchabun area. As you’ll get told every place is different. If you’re on a Non O marriage that’s should be easy to get bank account without Yellow book though. In the end I had to go to Krungthai. Some banks will have an issue with your initial visa only being 90 days. As you’ll soon find each branch may interpret the rules differently and ask for extra documentation
If all your ducks are lined up it should only take two days and a lot of patience haha. In nearly all places the staff are very very helpful.
