Minimum period for the bank statement is two months so I don't see how 45 days on visa exempt would work - or can I extend that stamp for 30 days again?

Yes but I know a lot if people who had no problem with renewals with a constant balance in the bank book for one month prior. Be that as it may, I will have to solve this without leaving the country as I would not be able to apply for retirement without a non-immigrant 0. It looks like I will have to pay 15-20k for a visa service just because of a drop of 500 Baht under 800k for one day.

Overstay has been categorically denied. I live in Khorat and immigration has undergone a major shake-up here. So it is more difficult to bend the rules even when they are new (this happened to me because it used to be one month prior to application not two).

Hello, I have a nasty problem. I entered with a Non-Immigrant 0 for three months to arrange a retirement visa. I had transferred the required 800k Baht. The balance slipped below 800k for 1 day on September 4th. My three months expire October 30th so that is too soon for a new bank statement on November 5th (Before you comment how foolish this has been - I knew I could not touch the amount three months after application, I did not know that I cannot touch it two months prior either). I was told at immigration today that I can't arrange the one-year retirement visa because of this one problem. Does this mean that I have to use a visa service after all? Because if I leave the country, I lose the Non-Immigrant 0 status and won't be able to officially apply for retirement on another visa type. Thanks for the info.
