Renewing Non-O Yearly Extension Based On Marriage

[connda]

I am currently on a Non-O 1 Year Extension based on Marriage to a Thai Wife. I got that extension at the Nakhon Ratchasima Immigration office last year, and have since moved to Chiang Mai.

I know that the immigration offices throughout Thailand are not uniformly the same. Each Immigration Office in different locations seem to want different paperwork.

So with that said, what documents, paperwork, and pictures will I be expected to have to renew and extend my Non-O based on having a Thai Wife when I go to Chiang Mai Immigration in March - and - how many copies of each of these documents will I be expected to bring with me.

It would be great to hear from someone who has recently gone through this process in Chiang Mai.

Thanks!!!
