I got it, finally.
I should just open a savings account at the Bangkok Bank on Posri Road. Then for transfer from the U.S., I would follow the steps outlined in the Bangkok Bank website. I shouldn't have brought up Bangkok Bank, New York, and confused the lady at the Bangkok Bank here and myself. Had I understood the process when I first came here, I would have opened my account at the Bangkok Bank rather than at Kasikorn where my account is now.
As long as I would have other transactions through my checking account at BofA where the pension is going into, it would be more convenient to transfer to Bangkok Bank only as needed. Transfer cost over an year would also be less if I transfer only 3 or 4 times a year. Plan B would be to get the pension deposited monthly and directly into the Bangkok Bank account.
Jimbo, do you think that I may be able to get away with the P.O.Box as my U.S. address that I have rented for receiving a variety of letters, at least during my initial period here when I am trying to figure out what am I doing here.
I also have to hope that at the extension time, immigration would be able to see the total transfer over a year and average that to a monthly number to figure out if I did bring in enough as per their law.
