Do I need to provide proof of marriage for my visa extension in Thailand?

That's your wife's cert to get from the amphor or however it's spelled

Rayong. Yes needed every year

You also need a tm 7 from immigration

What an embassy says and what Immigration requires, are two wholly different things.

Embassies are dependance of the Ministry of Foreign Affairs, while Immigration is Ministry of the Interior. Both these institutions do not communicate a lot between themselves, so there always is a lot of misunderstanding when you ask either one of them.

Their rules differ, so it is always recommended not to trust what an embassy staff member says about Immigration rules inside Thailand, and vice versa what an Immigration officer claims to know about rules regarding an embassy.

Married to a Thai wife foreigners will need a freshly printed marriage registry document from any Amphoe. It is called “kor ror 22” and Immigration wants to see a new one every year, when you visit them for the application to the next “1-year extension of stay based on being married to a Thai wife”

Go to Amphur for update stamp..10 baht in Udan Thani

In Phuket you need a kor ror 2 (marriage cert, not the one with the color graphics) from local amphur, updated no older than 60 days (it used to be 6 months). YMMV.

You need a kor ror 2 from local amphoe

At CW they do require a new copy of your marriage certificate each year (not the pretty part) that you and your wife will have to get from the Amphur before applying for your extension.

Get it and also make sure to copy the back side of the marriage certificate.

There has been a lot more control when looking for extensions based on marrige so im sure want to see proof that you are married. It's not a big deal to arrange the certificate

If it's in jomtien, then yes, you do.

Did mine yesterday, everything was meticulously gone through including a Google maps location to your house (officer did it there and then) which they printed off, also if you have children they wanted copies of blue book for them also, which wasn't required last time

Usually don't need it but it's only 20thb so I'd take one jic

It seems to be dependent on your office, in Samat Sakorn not required, but some do require so best check with your local office

You cannot renew a visa. You can apply for an extension. Each year is a brand new application, not a renewal.

An embassy has nothing to do with applying for an extension, that is handled by your local immigration office.

If you're in Thailand and want to apply for an extension based on being married to a Thai, you need to go to your immigration office and ask for their handout of requirements for a 1-year extension based on being married to a Thai. Each immigration office sets their own requirements so the only way to know what is required is to go to your office and ask.
