FYI, I was not required to present any banking info whatsoever to receive my O-A. What I did present was a letter from the U.S. Social Security Administration stating my monthly income, and a letter from a foreign client stating that he paid me a small sum each month for work done by Internet. This totaled up to the required monthly income of 80k baht. Both of there were "notarized"...sort of. As the "people" signing these docs were not present, what the notary gives is a sworn stamped letter which attests to the fact that I handed them these things. YES it's sort of a joke. But in my first foray into this arcane business, I can tell anybody...as long as you can find some way to make a plausible case that you have some income and your nose is not falling off from leprosy, you're probably going to be oK. I spent weeks searching for labs to do elephantiasis tests...in the end, it was all a waste, and unnecessary.
