In your experience, has that occurred or is it always one year from the end of a visa? I guess I could ask the same about an extension of an extension. Btw, this is NOT factoring in travel and trips, which I am told resets your 90 days reporting. Even so, even if you do travel, is the extension always one year long? In fact, is it the law?

No.
“en oh”
No

I never heard of extension of stay longer than one year. But I have had multiple such extensions of stay, last one was #14 of such, all consecutive.

 

Non-Imm B (BOI) - 90 days on entry extended out to 2 years upon obtaining a work permit. 

Heard of three years a while ago. Was with a particularly well connected agent and rather small consulate. Didn’t see passport myself, but think it was true.

It is important to distinguish between the validity period of a visa, and the maximum permitted permission to stay under a non immigrant entry.

 

I do not have time to check back, so this is from memory. I believe the maximum allowed validity period for a visa under the law is five years. That is why the Thailand Elite program uses renewable five-year visas when for one of the memberships that are longer than five years. The maximum length of a non immigrant permission to stay (or extension of the permission to stay) as I recall, is one-year, with severely constrained exceptions. 

Yes. 

An "extension of stay" valid for 2 years from the date of issue can be obtained if:

 

a) the company you'll be working for is a BOI-promoted company

 

AND

 

b) you'll be working for it's Regional Operating Headquarters (ROH)

 

I think there maybe other criteria involved, but the above are the two basic pre-requisites.

It depends on the reason for the extension of stay. Most expats are limited to 1 year for the common extensions.

 

If working or investing it’s possible to get longer extensions. Foreign diplomats/officials can be granted any length of extension. And a residents permit (PR), which is a form of extending a stay, gives indefinite leave to stay.

Thank you ALL for bringing up exceptional cases: work permit, elite visas,... 

 

On the other hand, in most usual circumstances (marriage visas or retirement), it is a one-year extension.
