What documents are required for a 1 year marriage visa extension in Koh Samui?

I just wanted to share our experience for the 1 year extension file based on marriage done at Koh Samui immigration.

There is no clear list of papers needed on their website and a few papers that were needed, were not written on the list that was showed at the immigration office (related to the rented house we live in).

The list below may not exactly apply to you, it applied to us, foreigner husband and Thai wife, with 400k THB in bank for 2 months before applying at the immigration office, who rent a house from a private individual where we live.

Note that everything has to be done in 2 copies and EVERY COPY NEEDS TO BE SIGNED BY THE PERSON IT CONCERNS (all passport copies signed by me, id card and blue book of wife, map and Google map print signed by my wife etc.).

Orientation of photocopies is important, general rule is that the file will be made of A4 papers held vertically by the immigration officer, all copies and pictures should be able to be read that way without turning the pages 90 degrees, except for the passport pages (visa and stamp).

So here was the list of documents that we needed to apply for the extension (once again, 2 sets of all that) :

- khor ror 2 paper, dated copy of the marriage registration, recent one, obtained from your local municipal office

- original khor ror 3 copy

- TM30 registration print : the foreigner has to be registered on the immigration website, to the house you live in, just print the page once your passport and name appear on the extranet immigration page (orientation did not matter)

- passport first page copy, oriented so it can be read when holding A4 the page vertically

- passport visa page copy, passport oriented horizontally (2 pages) on top of the A4 paper

- passport last stamp page copy, passport oriented horizontally (2 pages) on top of the A4 paper

- TM6 entry paper copies recto verso

- ID CARD of spouse, copy recto verso (same orientation principle, can be read when A4 page is held vertically)

- Blue book copy of spouse (because my spouse ID is register to a different house)

- Rental contract

- 2 different photos from spouses together inside the house, ideally, horizontal oriented pictures so you can print 2 on the A4 page on top of one another

- 2 different pictures from spouses together outside the house, WITH THE NUMBER OF THE HOUSE VISIBLE, AND ONE OF THE PICTURE MUST HAVE THE WIDEST POSSIBLE VIEW OF THE HOUSE AND ITS NUMBER (ideally should be the whole front of the house) - this is important and the file won't be accepted without one, the house needs to be recognizable for the people who will come visit

- manually drawn map to the house you live in, in Thai

- print of satellite view of the house you live in with latitude and longitude (Google maps prints from a computer includes those) - so your house can be found (page orientation did not matter)

- Blue book page copy of rented house

- ID card copy recto verso of owner of the rented house, signed by that person

- Blue book page copy of owner of rented house and registration, signed by that person

- proof of financial means, for us was 400.000 THB in bank for 2 months, to do that I had opened a blocked account to put the money in, and asked statements from the bank, along with bringing the bank book to immigration. But blocked accounts do not show total on account after each operation so officer was a bit confused for a while, and asked for copies of the bank book on top of the statements issued by the bank. They are used to normal accounts where the total present on the account is recalculated after each operation. Just to say, bring your bank books even if you get a statement from the bank.

We filled a couple of straightforward forms at the immigration office on top of that.

We needed quite a few more documents compared to the list with my wife being registered to a different house, and needing the owner of the house we live in signed ID card and blue book copies.

The list of documents is non negotiable, meaning there is no point to argue with the officer checking your documents. They do not decide to accept your visa extension or not. They just check all the documents for the file to be accepted and your application taken under consideration.

Let your wife do the talking patiently if you do not speak Thai yourself.

In Koh Samui, a small office outside does prints and copies, so bring all originals with you and have your pictures stored on your phone along with pictures of your documents etc., should you need to print something again.

After that, we were told to expect a visit to our home the next week to check on us, and it takes about 4 weeks for the decision on the visa extension to be approved.

This is just our experience to illustrate all the papers needed at Koh Samui in our case, fingers crossed until the approval in 4 weeks, good luck to all.
