What are the requirements for renewing a retirement visa in Hua Hin using the 65k per month income method?

I don't have experience with the monthly income method, but HH immigration has never required anything from me other than a bank statement showing that I've been holding the k each month. No special documentation required.

The last time I did it in Jomtien I had to show a pension statement. That was in August last year.

I got this list from Hua Hin. The wording is is unclear, but as is often the case I think they missed the word 'or' from the list. I have not used the 65k method, but I believe your bank statement should be enough.

Not wholly relevant but last week I renewed my O-A retirement visa in Chiang Mai for the first time. Same requirement: 65,000 baht international transfer in per month.

I had to provide a stand-alone statement of International Transfers into my account going back for 12 months.

The local KBank branch (not my home branch) that handles International business was familiar with the requirement and produced exactly what was needed.

In addition I had to provide a full bank statement for the last 2 months so that the international transfers could be cross-checked.

The IO told me that for my next extension I’d need to provide 12 months of full bank statements in addition to the International statement.

You should be fine with the year transaction detail print out that shows you transferred in to a thai bank account in your name only from abroad a minimum of 65K baht each month, every month, for the previous 12 months before you apply for your next yearly extension

I would say post on a Hua Hin group and ask as well
