You can get two years from an OA, and this is probably the best strategy when the intention is to switch to 65k transfers. Although the actual changeover from OA to O is clunky (requiring leaving the country and reentering on visa exempt before applying in-country for the 90-day O visa), it offers flexibility of easily opening a bank account (so saving money on an agent), and it avoids tying up 800k dead money. Wisely invested overseas the interest earned on that 800k will pay for the mandatory insurance required for the OA
Best strategy is to move onto the 65k per month international transfer method. Saves having to tie up the lump sum year after year, and you can use the money
It sounds like you're not quite doing the right thing, if you're so frightened of having your account frozen. Perhaps you're better off using another bank, although I suspect other banks will eventually follow suit as far as long-term visas are concerned
From what I've heard it's four months, but you have to leave it in for three months anyway, and then you can still only withdraw 400k, as the other 400k can't be touched.
The only people it has affected are those who use visa agents (800k baht in and out the same day), and they're the ones who are whining. Those who do the right thing are unaffected.
Agent not required. 22 years in Thailand. I know the system inside out. Are you the same Todd McGowan who twelve months ago was telling everybody that the DTV extensions will cost 10,000 baht at immigration, and 10,000 baht each time a holder re-enters? I rest my case. Yeah, you really know how it works don't you? 😂😂😂😂
