I am currently on a non-O retirement visa. I started with the 800,000 in my Thai bank but have been making deposits of 65,000 or more every month without missing any month for a year now. My visa will need to be renewed in 90 days as I just did my 90 day reporting yesterday. Can I use the money in the bank and go below the 400,000 and switch to the required monthly deposits from my US bank when I apply for another year extension without an affidavit of proof of income? Hopefully I used the correct terminology.
