what exactly did you get in England? An O-A retirement visa? Because that 100% DOES require a background check AND insurance. An O in Thailand does NOT.
So you’re either being very unclear about what you mean, or completely wrong, which would be strange considering you’re on your 3rd year. Granted, you are getting on a bit now (just kidding, but have you taken your medication yet? Just kidding!) 🤪
you asked the wrong people in the wrong place, as you are discovering. I hope someone without an obnoxiously miserable and pitiful attitude answers you soon 🙏🏼
say for example you DID have your own PRIVATE pension fund. You’d be putting your income into the fund and paying out to yourself each month. You’d be able to issue the letter yourself and nobody would have any right or means to question it.
