What do I need to open a Bangkok Bank account for my retirement visa in Hua Hin?

Try the one next to market village. Need resident certificate, alternate id such as US drivers license and passport

Do it now

In my experience opening the bank account was the most challenging part of the visa process, so I would do this as soon as possible.

I tried at all the banks in Bluport first, but ultimately managed to get the Boontavorn Bangkok Bank branch to open one.

They sometimes insist on you buying an accident insurance policy from them as a bit of a "sweetener".

More recently I have read people stating the only way to do it now is to use an agent and that costs about 3 to 4,000 Baht.

When you go, dress smartly, be patient and polite and explain that you want to deposit money for retirement.

You need to get a letter from immigration first. Take all of your documents with you. If possible take a Thai speaking friend with you to assist.

Good luck.
