That's the endless, unanswerable question. And really has nothing to do with this thread. Fortunately, prior TM30'sare not required to enter the country.
We're off on the wrong tangent. My question was about limiting my trips to Immigration and dealing with bureaucracy.
Back when we first got our Non-Imm O visas, using the 65k/mo method meant buying a letter from the US Consulate. Another round of bureaucracy! Then when Immigration stopped that practice, there was no other method than 800k in the bank. Now, of course, we could each do a 65k transfer every month from our investment accounts to "prove" our income. That would be 130k a month and there is no way we can spend that much living in CM. That still means multiple trips to the bank here, then multiple trips to Immigration. And the excess funds I converted from USD to THB? What do I do? Take them out of the Thai bank with an ATM card and convert the baht to dollars and then bring that back to the US and deposit the cash?
Good point. I've seen a few of those reports too. But not much I can do about it. I can't worry about things I have no control over. My savings account has been open for 19 years so hopefully the bank never questions it. In my case, it's a risk worth taking to switch to a DTV.
