Does your immigration never verify your money via statement and certification from your bank that it’s your account and money came from outside the country?
You get the nonO visa from the Thai embassy in your country.
You enter Thailand.
You open an account and send 800k THB (must say “foreign transfer” on the statement).
You go to the immigration and get a one year retirement extension near the end of your visa.
If one branch doesn’t let you open an account, Goto the next. You might need a proof of residence from the immigration. Best chances are Bangkok bank, then Kasikorn.
That’s what wanted to do, but it ended differently.
The first lady (damnit why is my phone capitalizing that?) accepted it and said “done”. But I wondered how I could prove that I “paid taxes” without paperwork!
An hour later the boss of the Buriram revenue office had compared the taxes I paid in Switzerland (on the full amount I get) and those for Thailand (only on what I transferred) and I had a paper in hand that stated 0 taxes, plus a good laugh for “you can try to get back the 38k taxes you overpaid in Switzerland”.
