What are the current requirements for a Thai spouse extension with a NON-O visa, and do I need an updated Kor Ror 2?

Okay, people as easy (and cheap, just 20 baht) as it is to get a new Kor Ror 2 from ANY Amphur in Thailand by just walking in with the marriage certificate, your thai wife and asking for one I can't see any reason to debate on whether you need a new one or not .

We are done

Got mine last week at CW. Arrived 8.30am on Wednesday, left the building at 10am. A new KR2 was not required.

as far as what's required

If you're a foreign female with a thai husband, you don't have proof of funds (you MIGHT have to show his income/pay stubs)

-copies of the relevant pages of your passport

+data page, visa sticker, previous extensions, entry stamp, current extension, TM6

-husbands thai i/d card and house book listing

-hand drawn map to your house

-photos of you two standing in front of your address numbers

-photos of you two sitting on the couch or at the table

-Kor Ror 3 & updated Kor Ror 2

-TM30 receipt

-lease

filled out TM7 application for extension 1900baht

You will need a new KR2 from the amphur. Although it sounds like a cop-out answer, I would advise getting in touch with your Immigration office to see what their requirements are as they all differ quite a bit.

The queuing at Chaengwattana is too hit or miss to predict. No one can tell you how many people will be in Section L when you get there. It's gonna take as long as it takes. I'd avoid Mondays/Fridays and any week that has a holiday in it when the immigration office is closed

I had messaged you the answers but will allow your post

Most offices are requiring the Kor Ror 2 be no older than a year. SOME require a new one every time. Face it, just go to the Amphur, pay the 20 baht and have them print you a new one
