Where exactly your going to process your NoN-O visa (Thai Family). if inside thailand need bank statement, (show money) documents that your married to a thai and you both process in immigration. or else better ask the immigration officer in information.
Hi, I'm also married to a thai but If a foreigner man married to a thai woman it requires you to have a bank statement but if you married to a thai Man doesn't require any bank statement at all.
You will need 1 photo, 1 passport copy first page with signature , 1 copy of your last stamp with signature and tm7 form fill ups and don't forget to put your Address in thailand and contact number or Email thats all they need. and last your 1,900 baht payment.
