I’m with Krungthai bank, in a very small town in Nongbualamphu, the first time I went and asked for bank statements and paper work for immigration there was 3or 4 bank staff all huddled together, they got it right and immigration where happy with what I gave them
John take everything and copies of everything wife’s blue book passport telephone contract with your number and address on it, I didn’t need certificate of residence because we have our own house, if you have yellow house book and pink I D card take that
immigration told me I could apply for a marriage visa in country if I had a Thai bank account, but it would be easier if I apply at my home country Thai embassy on line e visa which is what I did, fill in all the paper work and sent bank statements and proof of address etc etc if you make a mistake don’t worry they will email you back requesting what ever they need, they are very good, I got my visa after about 3 weeks put it was during son gran
