Can I convert my DTV visa to a retirement visa in Thailand?

You need 800,000 in a Thai bank account.

Applying for any other visa cancels the DTV immediately.

Yes you can convert from a DTV to a retirement visa just the same as you can from any tourist entry. Visit your local immigration office and ask for the requirements but generally you will need 800k baht in a Thai bank account in your name only and between 15 and 21 days left on your current stamp depending on location to do so

Kevin Mason . . . It is a similar situation with a Non-Imm-O/A visa

*** it comes with a multi re-entry permit in the first year of the visa validity

That’s why you just cannot get it cancelled by simply exiting Thailand before the visa validity hasn’t expired

You would have to wait until the visa validity has expired. After that date, you have no more re-entry permit, so any stay permit that was stamped beyond this date, will become invalid upon exiting Thailand, and only at this point you are free to apply for another visa

*** It is exactly the same situation with the DTV, with the only difference that its visa validity is 5 years compared to the 1-year visa validity of a Non-O/A visa

No

that could be very difficult, because the DTV visa validity is 5 years and it is multi re-entry included, which means that you just cannot invalidate it by exiting Thailand without a re-entry permit - you got one that is valid for 5 years as well! You need to be off a visa, or off a stay permit, in order to apply for another visa. You can ask your Immigration if they are willing to cancel your DTV or the re-entry permit that goes with it

I think you need to end your current visa. Then apply for a new one. So research how to end your current visa, re enter under a visa exemption and apply for retirement. Let’s see what others way more knowledgeable say? I am following for the knowledge?
