sorry, I’m not at retirement age yet. I’m married to a Thai so it’s a bit different. I’m just trying to help via the internet. Take my suggestion and join the Thai Visa Advice page. You’ll get your answer there very quickly. Sorry about that.
It is important to note that renewal of a Thai retirement visa is subject to the same requirements as when applying for the visa for the first time. In addition to this any proof of funds in your Thai bank account must have been deposited and cleared at least 3 months prior to your visa renewal application date.
As well as providing proof of your current income and bank balance you will also be required to supply the following additional documents:
A completed TM7 form. (You can download this TM.7 Form from our website)
Your passport.
Two passport sized photos (4 x 6 cm).
Copies of your passport and the relevant pages.
A copy of your bank book or passbook.
A letter from your Thai bank confirming the status of your account.
The current fee for Thai retirement visa renewal is 1,900 Baht (non-refundable)
that was my number one concern, trying to board the plane with a one way ticket. I may just book a cheap flight out of Thailand just so I have something to show them.
