Good point. My dedicated account is with Krungsri, and I had to make 20 Wise transfers to accumulate the required 800k!

Can prove an uphill struggle, though, according to this ongoing thread:

And there's no way of knowing what info is revealed to an immigration officer when he or she swipes the photopage of your passport through a scanner, as seems to be universal practice worldwide these days.

Because neither of his parents are Thai! Presumably your stepdaughter's mother is Thai?

Definitely complain to the CAA* if I were you. Quite apart from the general discomfort which you had to endure throughout the flight, it strikes me as blatantly illegal if you were required to occupy a seat in which you were unable to buckle up during take-off and landing (plus any turbulence encountered during the flight). * https://www.caa.co.uk then click on the "Contact us" link in the bottom right-hand corner

Sadly this is all too typical of most MPs' attitude towards expat voters registered in their constituencies, I think.

I seriously wonder whether that might lie at the heart of the difficulties which a fair few on here have been experiencing recently with their Wise transfers. Presumably Wise's partners in Thailand these days are now only Bangkok Bank and Tranglo*? * https://www.tranglo.com/ EDIT - although I see that @anchadian has also referred to the Global Pay channel, whoever or whatever that might be.

If using the 800k method for retirement extensions as per the OP, best to open a separate dedicated account for this purpose IMHO - but not one with BBL in view of the delay in obtaining 12-month statements, which all other banks AFAIK can (and do) issue on the spot.

A Google search of "qatar airways reviews" yields a mixed bag of comments.

You must have been extremely lucky in being able to stay under the TM30 radar in your dealings with Rayong over the years! I was asked for this form way back in 2016.

Makes me wonder who was Wise's partner bank for @NanLaew's previously instant transfers - Bangkok Bank themselves or Kasikorn? My understanding (and, indeed, personal experience) has been that instant transfers are only possible where the partner bank is Kasikorn. So might it be the case that Kasikorn aren't a Wise partner bank any longer (in which case the default partner bank option for his transfers is presumably now Bangkok Bank and their 14:00 payment time)?

Yep, instructions to do SFA as I stated, thank you very much.

I was under the impression that most immigration offices were already accepting - nay insisting on - bank statements. And what an earth do you mean by "entitlement letters"?

So what about the equally - if not considerably more - stupid rules which the powers-that-be back in your home country no doubt impose on Thai nationals who want to settle there?

"Embassys doing their own thing" = "Embassys doing SFA" IMHO.
