I believe it is only 2 months the first time you get an extension of stay and 3 months for each additional extension. Best to play it safe. You have time to get your money here. I got my first yearlong extension 3 weeks ago. I did based on the money in my Thai bank account.
When I got my year extension two weeks ago the officer stapled to my passport. Now when I fill out a new arrival card I immediately take a picture of it and store in my immigration album in iPhotos.
I keep that amount of money in my Thai. It’s doing as much good there as it would in a USA account but more importantly it serves as an emergency fund readily available in Thailand.
I would expect it to be a service for the patients mostly. Otherwise word would get out and it would be mobbed. I kept hearing rumors about it though . . .
I know someone who works there. She is going to ask on Monday. If that doesn’t work I will go myself next week. It’s near Duke Language School. I start school again on Wednesday.
I have my pension and Social Security deposited in my US bank accounts monthly. What I did over a year ago was transfer the 800,000 baht and some more for working capital to my Thai bank. I transfer money from the US periodically but I never have less than 1,000,000 baht in my Thai bank. When I got my year extension last week the money was seasoned and I had no problems getting the extension. The money also serves as an emergency fund here in Thailand.
I just got my one year extension using my Thai bank account but I was under the impression I could have used my income as well. I just didn’t want to pay the $50 US consulate notary fee.
