Why is my multiple entry retirement visa not being extended upon return in Thailand?

The important question is...

What is the Visa or Extension of Stay that you have in your passport?

Is it an Extension of Stay based on your being retired?

And obtained inside Thailand ?

AND did you purchase a multiple entry re-entry permit ?

David I deleted one reply from you on this post of yours.

We do not allow any discussion of Thai visa agents on the forum.

Then again, I could be totally wrong 😮 (shocking as that might be for everyone 😛 ) ,

So let's start out with WHERE did you get this "multi-entry retirement visa"?

Did you buy it from the thai consulate in your country before you came here (where it required a background check, a medical certificate and proof of funds in your country)

OR

did you come here and get it issued inside the country at an immigration office (which would have been a 90 day Non-O visa, followed by a year extension of stay and then a multi-re-entry permit) ?

That will tell us right off what's what with it

I would bet that you do NOT have ANY visa at all and if you looked at your stamp you would see it says "extension of stay permitted until" and has a date stamped for how long that extension is good for

AND

I would also bet that you have a multiple re-entry permt (another stamp) that's good for that length of time as well.

That extension and re-entry doesn't get you stamped in for a new year when you come back it gets you stamped in until your current extension expires.

The ONLY visa that gets a year entry stamp on entry is the year-long, multi-entry OA visa you by at the thai consulate in YOUR country before you come here.
