Do I need to maintain 800,000 THB in my bank account if I switch to a monthly income visa extension?

I believe it is either/or but since you started with having 800k baht in the bank and plan on switching to the monthly 65k baht deposit I would meet both requirements just in case they apply one rule but not the other. This way you’re covered either way and you should (5555) be able to transition easily to the 65k baht a month criteria.

Give them fewer things to think about, fewer reasons to say no, and have a smile on your face. The IO’s in Udon Thani are awesome by the way. Probably doesn’t apply where you are though.

You stated you extended your "O-A" visa...is that what you did?

I thought it was EITHER OR, not both proof of 800K bht AND 65K per month income?

I would hazard a guess that IF you started transferring in to the country in to a thai bank account in your name only the minimum 65K baht a month NOW so that when you apply for your new extension next year you have 12 months of international transfers that you would meet the financial requirements via the monthly income method BUT to keep the extension you have now valid you would still have to follow the terms of the extension which is bank the money 2 months before you apply, keep the balance above 800K for 3 months AFTER you got the extension AND don't let the balance go below 400K baht the rest of the year.

Even if you were transferring in the 65K baht a month, they could look at your bank book and IF you didn't follow those terms that were required for this extension say that you lost the extension the minute you violated the terms of it.

You got 1 year Extension of Stay based on these conditions. What ever you like to do in the future, you have to follow the conditions of this Extension of Stay to keep it valid

When you got your extension this time were you given a paper that told you to update your bank book and return in 3 months to show the balance was still at 800K baht?

Good question.(y)
