Can more than 1 Thai bank account at the same bank in the same name and been there for years adding up to over 400,000 be used for extension of stay based on marriage ? According to the immigration office today the answer is only 1 bank account. I cannot find anywhere on the web that's says that. One site does say that all statements ( plural ) and guarantee must be provided of which was done .Has anyone heard about that before. Had to pay 1900bt for 60 day ext and come back and apply again in 2 months when all the funds are in 1 account for 3 months and pay another 1900 bt. Been here for 10 years too.
