I did banked method last year and kept the right balances this year. Question: when I go in, will they give me a years extension, or just three months and I have to go in again after three months to get the year? I forget how it works.
could put the 800k in a Bangkok Bank Fixed account and at least make some meagre interest on it. Plus it’s easier for Bank staff and immigration to review financials when it comes one year in. Just a suggestion.
Not sure if this is helpful: why not get pension paid into UK bank account; then use Wise to transfer, making sure to tick the “reason for transfer box” that says “Funds for longterm stay in Thailand.” (The code you get doing it this way is proof of international transfer.)
