I checked with Thai immigration and as I already stated , when the borders are open you can go to a Thai embassy and get a non immigrant visa for marriage.
I think you can cross the border , when it's open , and get type O visa. Then on return apply for the marriage visa after a couple of months. 400.000baht in Thai bank account.
Very easy. Home country driving licence( I didn’t have to translate the licence) Proof of address, Medical certificate easy to do. at the driving centre you will get an eye test. Passport.
Thankyou for the reply. I’m already on my second year. Just had to go up to the Thai border ,cross over to Myanmar and get a stamp. Return to immigration and everything done. Never had to show bank account details .I visited immigration recently and can extend the OA for another two months. Just buying time but worth it. Hope the border situation is open for farangs then.
