What documents do I need to extend my retirement visa in Thailand?

Hua Hin. Bangkok. Tha Phanom. Each office and bank branch has different requirements and doesn’t apply to the OP. I think the OP has his answer and I’m closing comments.

last week got 12 month print out of account.

bank letter confirming my account

with branch.

took about 15 minutes.

Bangkok bank.

huay kaew rd branch.

Krungthai in hang dong can certainly do a 12 month printout whilst you wait.

Why don't you just make copies of your bankbook ?

I've always done it like that. A token transaction on the day I apply for extension, update the bankbook, and make the copies.

Just go and get a statement printout every 6 months. I do this with Bangkok Bank. Immigration accept every time.

Is SCB the only bank that can print out 1 year? K bank can print 1yr?

I had this problem last year so I moved the money to SCB who can print out a year and give a letter there and then. As a precaution, as I closed my BKK account, I got a statement from them- 4 months after my extension, then ,with the SCB bank letter from the start of that account- month 4 to month 12, CM Immigration were happy when I presented both, together with both bank books. Next year no problem as it is now firmly in SCB. Not sure what the policy of other banks is, but the week delay makes the statement invalid I think as Immigration want a one the same day or maybe not more than 1 day old, I think it depends on the office.

it has been that way since they implemented the requirement that the money stay IN the account 3 months after the extension was granted AND then the balance doesn't go below 400K baht the rest of the year.

Most banks take 3 - 5 days to get it because they only have 6 months on file that they can print on demand.
