I'm planning to pay the office a visit before I extend to ask for a list of the specific requirements, but I'm not sure if they have anything to give me? I couldn't find anything on the immigration website.

So, just in case, does anyone have a photo or link to the latest requirements for the Non-O spouse visa extension in Chiang Mai?

If not, I'd be really grateful if anyone with recent experience (last few months), could answer these questions:
 

1. Do I need to (or am I able to) do my 90-day report before submitting the extension application or do I just included a completed TM.47 form with the application? My Non-O visa is obviously only valid for 90 days until extended, so I'm not sure about this.
2. Do I need an updated Khor.Ror.2? If so, how many original copies and how recent (e.g., within 7 days)? Can a farang obtain these using a copy of his Wife's ID?
3. How many original copies of the bank certificate and statements are required? How recent do these need to be?
4. Do also need to update my Bank book and provide copies? Does this need to be done on the day of the application? 
5. Do a certain number of witnesses need to be present or will a house visit by immigration be arranged at which a certain number of witnesses will need to be present?

Any other tips would be much appreciated. With things like this in Thailand, it's always the lack of clarity and consistency that makes these things seem so much more complicated than they should be.

Many thanks in advance.

 

 

 I am not in Chiang Mai but the following are what I take every year to my local office.

 

Requirements: 

 1.  ONE completed TM7 - +2 pictures.

 2.  Proof of funds.  400K for 2 months.  Bank Letter + Bank Book. The bank letter must be dated the SAME DAY AS THE APPLICATION AND INCLUDE ONE TRANSACTION.

 3.  Photos of you and your wife around the house. One with you outside clearly showing the House Number and 2 inside the house. 

 4.  Marriage certificate and updated Kor Ror 2

 5.  Wife’s ID and House Book

 6.  Driver’s License (photocopied)

 7.  Map to your residence. 

 8.  Passport and departure card (photocopied)

 9.  House book/Copy of rental agreement or lease

Thanks for taking the time to share this, @South. I've read around pretty thoroughly, so am aware of all the general requirements. But there's such variation between offices, I'm hoping to find out specific info for Chiang Mai. My wife is away a lot, so we only have a limited window to do the application. I want to know the absolute requirements for Chiang Mai so there are no surprises on the day, as well as what I can prepare beforehand myself to save time and make this less stressful.

I may head to immigration on Monday or Tuesday to ask, but I'm not sure whether they have anything official, so the 45-minute drive could be a wasted trip.

Neither. Do nothing. First extension starts your 90 day clock. 

 

Here is link to general requirements. Immigration offices do vary.

So I've just read - thanks. I didn't realise the visa extension supersedes (or replaces) the 90-day report. However, based on what I read, it then seems to be a lottery as to whether you do your 90-day report 90 days after the application date or 90 days from the extension stamp. It's a case of seeing what 90-day report reminder you're given, if any.

In addition to the above list provided, some offices may require an owner-signed copy of the the chanote of where you live.  Housebook copy should also be signed by the owner. 

Some offices want the map hand-drawn - others a google-map  is fine - I always brought both.

Bring a 10+ of pictures - not "selfies" (can use the timer-function for a phone) - let them pick the ones they like.

If you have an old/previous passport, have that in your bag, in case they ask for it.

I presume that CM IO do a home visit and interview, 2 neighbors as official witnesses with signed copies of their id cards, for at least the first application of a 12 month extension, will she be around for that?

I've no idea whether they do, but I'm aware this may be needed. There's nothing official posted anywhere. That's the really frustrating thing about all this. If it is needed, we'll need to negotiate the day and time to ensure she is here.

From your experience, are the ID card copies and signatures normally required for the application or at the time of the house visit?

@Rob Browder @Packer Thank you both. I'm aware of pretty much everything that may or may not be needed (although, the Chanote was news to me). I'm going to immigration tomorrow morning to ask about everything - and hope they have some sort of official, up-to-date checklist I can refer to. I don't trust the spoken (or emailed) advice I'm given, as I've been told so many contradictory or wrong things by members of immigration-related staff in the past.

If they want a 90-day report done, the immigration  "advisor" under the tent will tell you to walk around to the 90-day drivein window and they will do one for you right then.  Some of the IO's like to have a copy of every page of your bank book too besides the bank documents.  My bank in CM knew what the IO wanted from the bank and they always prepared what I needed for that visit to immigration.

Thank you.

Did the bank updates and documents all need to be dated on the day of your application? That varies between offices. What about your Khor.Ror.2?

@ettcuk realize this attached thread is very old (2021) however the OP has excellent first post outlining (in detail) his experience. 

Obviously some info out of date however worth a read to confirm your current understanding. 

 

 

@ettcuk

This is a comprehensive list of documents that may be requested by an Immigration office.

I posted this previously as a PDF to a number of members who reported success.

 

Extension of Stay based on Thai Spouse.
Thai Immigration Police Order 327-2557. (2014) Section 2.18 – Marriage.
Thai Immigration Police Order 138/2557 (2019) 

For the very first application of a 1 year extension of stay based on marriage, you must have been granted a Non Immigrant O type Visa.
The financial requirement are either;
1. FUNDS METHOD. Updated Passbook, Bank Statement showing 400K Funds deposited in a Savings or Fixed Term Deposit account in a Thai bank in your sole name, for no less than two months prior to the date of application + bank letter OR
2. INCOME METHOD. A proof of Income letter from your Embassy/Consulate, OR
3. INCOME METHOD. Updated Thai bank Statements/Passbook showing monthly overseas transfers of 40K minimum for the previous 12 months prior to the date of application + bank letter.
4. If using either FUNDS (1) or INCOME (3) in a Thai bank account, then a bank letter addressed to the Immigration Commissioner confirming: Account name, number, and balance issued by the bank is required. The balance on the letter should match the balance in the Passbook/Statement.

Applications for an extension of stay based on Thai spouse must be approved by the regional Immigration office, therefore you should supply two matching sets of the documents listed below.

                                 
Documents for an Extension of Stay Permit based on Marriage.

1.  Completed TM7 form. (Must be printed on both sides of 1 A4 sheet)
2.  Passport photo's 4×6 cm.
3. Your passport
4.  Copies of all pages of your passport with stamps, including the data page
5. Copy of TM30 receipt
6.  Copy of Wife's Tabien Baan 
7.  Copy of Wife's ID card 
8.  Copy of Marriage certificate. (Khor Ror 3) 
9.  Updated Marriage registration (Khor Ror 2/22) 
     (Khor Ror 22 if foreign marriage registered at Amphoe)
10.  Copy of name change certificate (if applicable)
11. Map pinpointing and detailing address 
12. Photo's taken together 
    • Outside the home clearly showing house number.
    • Outside showing full house view.
    • Lounge
    • Dining area.
13, Proof of Address. (one of below 3 options)
Condo owners;
    •  Blue Tabien Baan (foreigners name will not appear in the book) 
    •  Title Deeds (Chanute) 
    •  Yellow Tabien Baan (if you possess one) 
Rented
    • Copy of signed owners/landlords Tabien Baan
    • Copy of signed owners/landlords ID card
    • Rental agreement 
    • If the owner/landlord is registered at a different address in another Tabien Baan, then a copy of that Tabien Baan + copy of Chanute for your address may be requested
Privately owned
    • Copy of Wife's Tabien Baan
    • Copy of wife's ID card
14. Proof of Funds;
    • One of the 3 options detailed at the top of the page

 

2 identical sets of copies of the above documents are required for extensions based on Thai spouse.
 

Additional Notes.
      
    • Both the applicant and wife must attend the application.

    • Copies of documents, pages, or photos should be printed singularly on 1 A4 sheet.

    • If rented, copies of house owners Tabien Baan & ID card should be signed by the holder and include their telephone number.
      
    • For the first extension application, Immigration may arrange a home visit where two Thai witnesses must also be present.
      
    • Your application must be approved at regional level. (Under 30 day consideration) requiring a return visit to obtain your extension stamp once approved.  
                               
    • An updated Khor Ror 2/22 (marriage registration) will be required each year. Available from your local Amphoe on request. (20 baht)  

    • Statements/Passbooks and bank letter must be dated the same day as the application.
            Certain Immigration offices may allow them to be a few days old.
            Embassy Income letters are valid for 6 months.

    • Mark the location of your address on Google Maps with the pin facility, then print it off. Manually write your address in a blank space in English and Thai if possible.
      Some offices may require a hand drawn map.
      
    • Do not pre sign documents. Immigration will stamp each document asking you to sign within the stamp.
      
    • If using the monthly income method, Immigration may request proof of the source of your Income, such as a letter from your Pension provider, Investments, or shares.
      Transfers should be made around the same time each month. Irregular transfers may be refused as unacceptable. I recommend you highlight the monthly transfers as the Immigration officers are less than familiar with reading passbook/statement entries. 
      
    • If using funds in the bank, it is advisable not to withdraw any funds until your application has been approved, and you obtain a new permission of stay stamp.
      

The onus is on you to supply any document requested. The above is a comprehensive list although not every document listed may be requested depending on the Immigration Office.

Many thanks, @DrJack54. I read this a few days ago and used it to add to my notes. But I'll hopefully get something up-to-date and specific to CNX from immigration tomorrow.

The first extension counts as a 90 day report, subsequent extensions do not. 

Yes, best to bite the bullet and make the extra effort to personally confirm their specific requirements.

 

Of course Murphy's Law will dictate that AFTER you have done this, at least a couple of Chiang Mai immigration user members will post their very recent marriage extension filing experiences. With the caveat that it may slightly vary from what an immigration officer has just advised you.

 

Good luck!

I have been doing what they call a retirement visa for 25 years. I used to live in an outer province and had to do it all myself - if I made a mistake they were always nice about helping me fix it, 

 

At Airport Plaza Immigration, there is or maybe was, a table outside with volunteers helping people filling out forms. 

 

Since moving to CM - I have been very happy to pay a nominal fee to an agent to let them take care of near everything for me. I use Assist Thai Visa and they have been terrific. I need to get my bank letter by myself, then go to the agents office where I sign all of the forms as they flip the pages, and then meet the agent at Immigration [usually the next day,  where I am needed for 1 minute while they take my photo and that finishes everything. The agent takes away any small worry about filling in the forms properly.

Extensions based on retirement and based on Thai spouse are two different kettles of fish.

For the past few years I have done my extensions based on marriage at the immigration office in Central Festival Mall - much easier, less crowded and better parking.  I began using an agent to prepare everything many Years ago after doing everything myself for over a decade and am very happy to not have to deal with anything any longer.  All I do is sign my name many, many times.  My agent does everything for me for a very nominal fee - under 10,000 baht including the immigration fee of 1,900 baht and also including all of the 90-day reports for the year.

By using the agent do they still:

 

Come to do the home visit and the agent isn't there?

They don't do a home visit due to using an agent?

I did this for my driving/motorcycle license and honestly sat there at the Transport Office with the agency rep thinking, "What am I paying for?"! I pretty much still had to do everything myself (original doc prep, medical certificate, etc. - they did the photocopying and checking) and had to drive 45-60 min to the Transport Office twice, as the agency hadn't realised an appointment needed to be booked the first time. No apologies or refund for the hassle (I didn't ask), they just asked me to come back again... But, other than that, I was paying for peace of mind.

I was quoted 16,800 THB for assistance with the marriage visa and reentry permit. That put me off, but I now realise it included the 1,900 THB fee for the extension and presumably 3,800 THB for a multiple re-entry permit. So, I guess they charge around 11,000 THB for the marriage visa (plus government fee) alone.

When you say everything for you, what about the photos, updated Khor.Ror.2, bank documents, etc. - all the things you presumably still need to do yourself? And don't you and your wife still need to go to immigration with an agency rep?

It's good to know this can be done at Central Festival Mall, as I'd read elsewhere it couldn't. That will be a much better experience - the parking and location.

Absolutely. Many thanks - what a bit of clarity and a comprehensive, regularly updated website would do?! Imagine the time and hassle saved for everyone on both sides of this.

As well as what liquorice stated you need the STM forms 2, 9, 10, 11.

Note that STM 10 requires a witness. You need to ask what they require for this. Some offices require the witness there at immigration.

With a quick search just found this page that has those forms. Ignore the others for wp.

Not sure about a website as the requirements vary and maybe some offices don't want their bit of the hokey-cokey overly-exposed.

 

Udon Thani did have an A4 fold-out leaflet that defined what was needed. It was in a tray just inside the door so you didn't need to ask. Just pick up a leaflet, go gather the required paperwork and return for a one-stop filing. I am not sure if they still do that or if it has been updated after changes in management, but it was very handy.

Even if your IO supplies a list of the documents required, you may find on submission there were omissions on the list, or they have specific quirky requirements.

 

My IO insist on one single copy per A4 sheet.
Copies of passport pages > multiple A4 sheets.
Copies of owner's TB and ID card > 3 x A4 sheets.

 

This year they refused the 4 A5 size photos supplied (4 x A4 sheets) stating the house number had to be white on a red background, orders of new boss. WTF!

For the last 10 years I've supplied the photo's, black numbers on a white background have been perfectly acceptable.

I took it up with the boss and he backed down. Nothing more than an ego trip and trying to stamp his authority as the new boss.

But, exactly yes - !! I pay my agent for peace of mind and it doesn't cost me anywhere near the figures you noted - - they take all of the angst out of the experience - everything is done quickly and w/very little effort on my part... If you can't afford it - ok - it can be an inconvenience but not difficult to do... for me, it is well worth the nominal fees... 

 

maybe getting a DL is out of their range of common activities for them... my agent said they didn't provide that service.

So are you doing extensions based on marriage or retirement. 

If based on retirement why even post when the OP is marriage.
