Hello! I have a handout of requirements for extension of non O visa at immigration Chaengwattana.

It asks for a copy of my last visa and my first visa.

Am I correct in thinking, the copy of first visa is the very first one into Thailand?

My first was in 2011.

Thank you for guidance.

TLDR : Answer Summary
The post discusses the requirements for extending a NON-O visa at the Chaengwattana immigration office, specifically clarifying the need for copies of both the first and last visas. The user confirms they are correct in understanding that the 'first visa' refers to the initial visa issued upon entering Thailand. Additionally, there is mention of differing requirements for men and women married to Thai nationals, which appears to have been confusing for some users.

Seems I have the handout for men married to Thai wife.

I've now seen the requirements for women married to Thai husband.

Issues appear resolved.

Thanks for your input.

That makes sense.

I was confused about the wording, as it states first visa and last visa. Then adds last extension.

When on a initial non OA visa, you need for each extension for stay to give a copy of you initial visa.

Stamp you're currently on and the previous extensions that are in that passport and if you got a new passport it will already have the transferred stamps in it
