you can get it once per visa/extension type, do if your burned it on the initial non o visa your current extension is from your done.
You may have to look at leaving, letting this extension run out, getting a new non o from the Thai consulate online before you come back and starting the extension process all over.
Kathy Spencer you will indeed get stamped in until November 2026 when you return to the country with new insurance,
you are correct when you go to exit the country again in April next year you will need a reentry permit and you will get stamped back in until November 2026
Don't confuse an entry stamp with the validity of the Visa itself those are two completely different things.
The Visa runs out in March that is the latest you could enter the country on it and get stamped in.
The entry stamp that you're going to get this November will be until November next year because you get stamped in for a year or as long as your health insurance is valid for up to a year.
So when you leave in April which is after the Visa itself expired you will need a reentry permit and when you come in you will get stamped in until that November 2026 stamp
If you get the OA visa from the thai consulate in your country before you come here, you get stamped in for a year (or as long as your mandatory insurance is valid for up to a year)
THEN
when that year runs down IF you got another year of insurance you could exit/re-enter before the visa itself expired and get a whole new year entry stamp (or as long as the insurance is valid for up to a year)
Most people on OA visas (who plan it out right) manage to get almost 2 years of stay out of that one year visa by renewing their insurance and bouncing out/back for the second year entry stamp.
However IF you're wanting to get OFF the OA visa you'd have to exit the country, get stamped out, then either buy a new 90 day Non-O visa from a thai consulate before you come back OR enter free stamp 60 day visa exempt, have the 800K banked in a thai bank account in your name only and apply for the in country 90 day Non-O visa at the immigration office where you live.
There is no way to "swap" an OA for an O without getting completely off the OA and starting the Non-O visa/extension process from scratch
There are over 80 immigration offices in the country and you do 90 day reporting based on the office that serves the address where you stay in thailand
You should be able to get in/out of that Nonthaburi immigration office pretty fast though WAY faster than queuing with the zombie horde at Chaengwattana 😛
right, that's when you'd be able to bring the balance of the account down to 400K and then once you got the following years extension using monthly income method you could empty the account as you'd be on an extension that used a different method of proof of funds.
