When can I convert my Non-O retirement visa obtained inside Thailand after arriving on a 60-day tourist stamp?

So you arrived on a tourist visa, applied for and obtained a 90 day Non-O visa inside Thailand (which will be stamped used). Your visa is now not relevant, all that is relevant is the date you are permitted to stay in Thailand until. You can apply for a 12 month extension of stay (not a visa) when you have 30 days or less left on your permitted to stay stamp, some immigration offices allow you to apply when you have 45 days or less. Best to check with your local immigration office and also get their handout of requirements

Just want to say advice on this platform is helpful in many ways.

Appreciate information from others who have gone through the process: whatever question is asked.

Cannot convert 60 day exempt, you gotta enter using the 90 day nu on O and then extend that for 1 year. Total 15 months. Why did you enter on a 60 day exempt when you already had a 90 non O ??

If you already have non o 90 days apply in thailand,and using yr stay in thailand with yr non o 90 days ,why worry abt yr 60 days visa exempt on arrival in yr passport.30 to 45 days b4 yr non o expire and go for 1 yr extention where you get yr non o.

Did you convert to Non O inside Thailand, or did you apply online at a Thai embassy abroad? Your post is unclear about how and where you got the Non O.

You’ll need to leave to cancel your current stamp and re-enter to activate your Non O visa. You can’t convert any stamps as you already have a new visa.

I’m assuming you’ve gotten the in country Non O rather than one you applied for via the evisa system.

If so you have the “retirement visa” already. What you’re asking is when can you do the yearly extension off of it.

The answer is when you have 30 days left (some offices allow 45 days) or less on that visa.
