At present i have a 1 year Retirement extention, issued in Ubon. i have just been asked if i am interested in a 3 month work contract in Rayong, and the company would obtain a work visa. I assume that the retirement extention would be cancelled and replaced with a work visa. What i would like to know is what is the procedure when the work visa is cancelled, and i need to re apply for a new retirement extention.

Most will suggest that you need to exit Thailand and obtain a Non B at nearby consulate. 

Here is a thread. My first post has link to another thread with post from ubonjoe.

Note: I assume you are not married to a Thai?

You would be aware that if extensions are based on marriage you can obtain a work permit. 

Has the company outlined their plan. 

As stated earlier... Generally you would exit Thailand and obtain a Non B. 

The company may be able to "facilitate" Something with immigration. 

My extensions are all based on the 800k method, i have already informed them i am on a Retirement extention so i will need to wait and check what the outcome will be. The issue for me is what happens when the job is complete and they need to cancell my work visa, as i will need to return back to a Retirement extention

It isn't worth the hassle to work legally for just 3 months.

@Isan Farang

Unless it's a veritable "pile 'o baht" I wouldn't even fool with it for just 3 months 
 

You'd cancel the extension you're on based on retirement, go to a nearby country, apply online with documentation from the new employer thru the eVisa web-portal for the 90 day Non-O visa, come back in get stamped in for 90 days, and then you'd be done with the 3 month contract before you'd even have to apply for an extension 
AND 
because you can only get an extension for the reason a visa is issued for the first time you couldn't use that 90 day Non-B to just switch to a year extension based on retirement,

you'd have to either go to a consulate and get the 90 day Non-O based on retirement or bounce out/back to get OFF that Non-B on to a free stamp entry, then apply in country for a new Non-O and after 2 months a new year extension.

That is a LOT of hoop jumping for just 3 months of work, and as I said unless it's a PILE of dosh it'd hardly be worth it (in my opinion 😉 )

Then, I would use the job as reason to change to a Non-O based on marriage - not a Non-B.  You can get a work-permit with this, and it does not expire when your job ends. 

You might have to go out for this visa at a nearby consulate, if your employer cannot arrange it.  The employer might monkey-wrench this plan, if they insist on using the "One Stop Service" (usually for BOI) - though they can, legally, just get you a regular work-permit.

Then, you can do your next 12-mo extension, apply based on retirement. 

Caveat - if you get a new Non-O based on marriage from a consulate, do at least one 12-mo extension before the job ends (can apply 30-45 days before it ends), because your first 12-mo extension from a Non-O Visa must be for the same reason as your Visa.
