Can I change from a Non-B visa to a retirement visa in Thailand?

If you are inside Thailand and have an Extension of Stay from Immigration (like example) you can switch to another reason why this Extension of Stay is based on.

There is a difference, but I understand. Everything in your passport is a Visa. So trying to help Chris Walker. If you entered Thailand using a Visa (like example picture) you can not switch at Immigration Office.

and I would say we're done.

Okay, first off the answer is NO you cannot go from one VISA type to another VISA type inside the country (except for going from a tourist visa to a Non-Immigration visa).

What you can do is go from an extension of stay for one reason to an extension of stay for another reason.

People routinely interchange and confuse the words VISA and EXTENSION OF STAY. They are not the same at all.

So if you are on the initial 90 day entry of a single entry Non-B visa OR if you are on ANY 90 day entry of a year-long, multi-entry Non-B visa (where you bounce out and in every 90 days) NO you can't get an extension based on retirement. You would need to get a new Non-O visa.

Now on the chance you're on an extension of stay based on employment (that you get from the immigration office or 1900baht) you CAN change the reason for your extension form employment to being over 50 (retirement).

You get a paper from your company saying you are stopping work on xxx day, you go to the immigration office CANCEL your current extension of stay based on employment and immediately apply for a NEW yearly extension of stay based on being over 50 (retirement) by meeting the criteria for that extension.

It most definitely CAN be done just like I outlined, BUT it takes having all your documents and proof of funds together for the new yearly extension, BEFORE you go cancel the old one based on employment.

If you are on the original Visa you bought at a Thai Consulate you can NOT switch to a Non Immigrant O visa based on being over 50 years inside Thailand.

If you mean change from an extension based on work to an extension based on marriage, the answer is yes - that's what I did. Didn't have to leave the country, just gave them the certificate I got from the labour office that stated I had left me job, along with all the other documents required for an extension based on marriage.

Potential follow up question - yes, I still got a work permit while staying on the marriage extension when I got another job
