marriage is of no concern with any retirement visa extension. It doesn't matter if you are married, or not, the financial requirement is bt800,000 in your Thai bank account for two months minimum before you apply, then it must stay in your account for three months after you get your year extension, then for the rest of the year it can never drop below bt400,000. Then bring it back up to bt800,000 at least two months before you apply for your next extension
