I am entering Thailand on 30 January with a Non O 90 day e visa from the U.K based on retirement.

I have an appointment at the British Embassy on 3rd February 08.30 for freedom to marry affidavit .

After that I have an appointment at the translation office in Central World for Express translation service.

On February 4th I have an appointment at 10.00 at the Ministry of Foreign Affairs on the 6th floor Central World for legalising my documents.

The following I am to get married in an Amphur about 25km from Udon Thani city.

I have a Bangkok Bank account. However the bank card expires at the end of January. I have entered on a Non O as so as to able me to open a new bank account with Kasikorn Bank.

I will return to the U.K at the end of February.

I will then apply for a Non O based on marriage to a Thai Spouse in the U.K and enter 3rd May until 1st June.

Before I depart I will purchase a single use re entry permit.

I will then re enter Thailand on 23 July and will need to extend for 12 months at Udon Thani Immigration. The 90 days will expire on 31st July.

I am grateful for all advice on these forums and I thought I had sorted everything. However I did not realise Immigration was closed for 3 days at the end of July.

Therefore I will need to have everything needed for the extension prepared so that I can get the extension in the limited time I will have.

What will I need for the extension at Udon Thani Immigration?

I could change my flight to an earlier date but will have to pay another 400 pounds on top of my original 1200 purchase price. This I do not really want to do.

Thanks.

Ok so currently not married and obtaining a Non O retirement eVisa to enter Thailand.

Your first extension will need to be based on retirement.

As a result you have lot of time to organize docs for second extension which can be based on marriage.

Be aware: that for first extension based on retirement the financial requirements are very different to that of based on marriage.

So for retirement extension you needed to season 800k in Thai bank for two months prior to application then maintained for 3 months after approval and not below 400k in other months.

You can switch to based on marriage for subsequent extensions

I will enter in January on a Non O retirement but will leave at the end of February which will end that visa.

I will enter in May with a Non O e visa based on marriage obtained in U.K.

The best advice is to go to your immigration office and ask them for the handout of requirements for a marriage extension. Each office sets their own requirements, and they have been fluctuating quite a lot lately, with some new forms, some new witness requirements, and other various things at certain offices. So you need the most up-to-date information. Get that handout when you are there on your first non-O so you can prepare everything in advance for your 2nd (third?) entry extension.

Seems different to your previous thread.

If you enter May with new Non O based on marriage you will be stamped in for fresh 90 days.

So seems first Non O retirement is just to open bank account.

Bit of a convoluted plan IMO.

It would be best if you visit Udon Thani immigration in May and ask them for their specific requirements, so that you can get everything sorted by the time you'll return in July to apply for your extension.

Take your wife along, as they might very well have specific requirements with regards to witnesses and/or the house visit that your wife will need to fully understand - as you won't have much time left when you return, you can't risk a "lost in translation" scenario.

His "return" second entry is with a new Non O (marriage)

He will have 90 day stamp.

OP did you consider first entry with visa exempt. Then marry in Thailand with the required docs you outlined.

Then after exit from Thailand obtain Non O marriage. Upon return to Thailand open bank account and season 400k for two months to obtain 12 month extension.

Yes, but he won't be in Thailand for most of those 90 days.

I did intend coming in visa exempt and marrying and returning with a Non O based on marriage in May.

However I want to open a Kasikorn Bank account and fund the account when back in the U.K. I have had problems before transferring money when in Thailand and do not want to take a chance on it not being seasoned.

Also my 5 year driving licence expires early March so in order to renew and get another 5 year licence I need a Non 0.

AFAIK, there are no extra hoops at Udon Thani immigration but salient advice from @Caldera to personally inquire nearer the date as things can change with government and local immigration shuffles. Udon immigration did provide a "cheat sheet" for applicants in the past that listed their exact requirements.

Since the marriage is happening at another amphur other than Meuang Udon Thani, I would make sure that they can fulfill the documentary requirements in a timely manner. Since they're all online and digitized, I'm sure they won't have issues but acceptable proof of addresses for both parties is important. Once, it's registered, the supporting documents such as the Kor Ror 3 (proof of marriage) that may be required by Udon immigration, can be obtained at any amphur, including Meuang Udon Thani.

The wedding certificate is Kor Ror 2 but despite the marriage being recent, I am sure Udon immigration will require a Kor Ror 3 from any amphur as long as it's less then 7 days old.

Good points. I would suggest keeping the Bangkok Bank account updated with new passport and address updates and you may also consider opening an account at SCB as well as Kasikorn.

For banking and transfers, Wise is the most efficient at the moment, so if you haven't opened an account with them, put that on your UK to-do list

Maybe just me. Your info is posted in dribs and drabs.

Now aware you have a BBL account.

That is adequate for first extension.

Obtaining a Kasikorn account after obtaining first extension is no problem.

As for TDL they can be renewed up to one year post expiry.

I tried to include everything in my original post and included that I had a Bangkok Bank account.

In my original post I did not mention my Thai driving licence as it was not really relevent to my marriage extension.

I know the driving licence can be renewed at anytime this year but I have been stopped many times before by the police and do not want to pay fines for no reason.

Yes I have a Bangkok Bank account but have read here so many problems with Bangkok Bank and extension problems,frozen accounts etc.

I previously was in Thailand on a retirement extension and would go to the bank and get a letter (nang sue rap long) and a statement for ฿100 each on the day of my extension application.

However as I will be extending using marriage and not retirement am unsure of procedure.

I have read people need to order a statement that takes a week or more and have read from others you just go to the bank same as on a retirement extension and it is issued there and then.

I want to move from Bangkok Bank to Kasikorn due to reports on here saying Bangkok Bank are a problem now for extensions ,but now am being told to stick with them.

The main concern is that I will not have enough time to submit my extension as am not sure of requirements.

Also agree that asking Immigration at Udon what they require is sensible however I can not ask them for several weeks and if I need to move my flight the sooner the cheaper.

Just trying to work things out.

The only bank statement that takes a week is Bangkok Bank 1-year statement. Bangkok Bank can issue a 6-month statement on the spot, and every other bank can do a 12-month statement on the spot.

Since a retirement extension only requires 2 months of funds (unless you are using monthly transfers), any bank should be fine. The only problem with Bangkok Bank is they will freeze your funds if it hasn't been in your account for 4 months. So for that reason I would recommend any other bank.

I am using ฿400,000 for marriage extension. I have a Bangkok Bank account but will change to Kasikorn.

Then you have nothing to worry about in regards to being able to get the required bank statement. You will be able to do it. It's just whether or not your funds will be frozen or not. But once you move from Bangkok Bank, that will no longer be an issue either.

I will visit Udon Thani Immigration and ask their requirements for an extension based on marriage.

I am interested regarding the updated marriage certificate from the Amphur. How many days in advance can I get this?

Also the bank letter and statement ,does it have to be issued on the day of the application?

Why cant you do your second visit on May 3rd visa exempt?

You will be here less than 60 days anyway and no need for reentry permit.

In that case you can apply for Non-O based on marriage in UK just before you are coming back on July 23 and have plenty of time to sort things out for extension

I am not coming on visa exempt in May because I want to have a long stay extension with re entry permit as soon as possible.

Whenever I enter it will only give a 90 day stay ,therefore entering in July on a Non O based on marriage ,I will have to wait until October to get the year long extension.

Therefore if I enter in May on Non O based on marriage I will be able to do the extension in late July and be on a yearly extension.

I have a car and a motorbike and Thai 5 year car and motorbike licence that expires early March.

The village where are home is has regular police stop checks for driving licences.

If I do not have a Non O I will only be able to renew the driving licences for 2 year licences and not get a valid 5 year licences.

I also want to open another Thai bank account and season the funds and this also requires a Non O.

As attached is the English section of the forms for 1-Year Extensions based on being Married with a Thai women and based on Retirement that I received at Udon Thani Immigration on November 2nd 2025.

Section 6. As for the Married version was somewhat confusing for me as it appears in the text that even if using the banked +400.000 Baht method on a Thai bank account. It looked like I would anyway need to get a pension income certificate from in my case the Swedish Embassy in Bangkok (which will stop issue these from October 1st 2026). But when asking a Immigration officer she told me that that is not required and that minimum 400.000 Baht as been on my account for minimum 2 Months is what’s required.

I asked also if my ”Fixed Account” at Bangkok Bank - Udon Thani branch is approved to use as it is this account that I plan for use for my extension. I asked because as in the forms it says the money shall be on a ”Savings Account” . I showed my ”Fixed Account Passbook in my name only” and the Immigration officer informed me that my Fixed Account is ok to use. She did write on a paper in Thai that I shall give the bank as for get a 3-Month Bank Statement and also a Bank Letter (I guess) as my understanding is that both these documents are required by Immigration.

As for proof we are married my wife visit’s the local district office (Amphur) in Udon Thani and they do thus issue a ”Marriage Register Document” as for us is a ”KOR 22” as we originally got married outside Thailand. As we did not got married in Thailand we don’t have any ”Thai Marriage Certificate” and besides that Immigration want either the ”KOR 2” (married in Thailand) or ”KOR 22” Marriage Register Document as it is this that proof we are still registered as married on the day of issuing the document.

Thanks for your detailed reply.

I notice it states 2 Thai witnesses have to attend bringing their id and house registration. Is this a requirement that they attend in person or just provide photocopies?

I believe only one as read 15. Quote: ”Thai Witness (Not relatives Person)with Photocopy of ID Card and house registration book”. Unquote

For your information I planned originally to apply for an 1-Year Extension at this visit based on that I arrived to Thailand with a Non O E-Visa as married with a Thai. But I have decided to this time only do a 60-Day Visit Thai Wife/Family Extension once again. After I get approved I and my wife plan to leave Thailand in end of March likely to stay in Sweden until beginning of October before going back to live in Thailand again.

I plan prior next trip to now instead apply for a Non O 90-day E-Visa based on Retirement and follow up with 1-Year Extension based on Retirement. I need to thus add currency so I have +800.000 Baht on the Thai bank account instead of +400.000 Baht of course. But this looking to me as the better option overall as how I look on it. In some few years after when starting receiving pensions thus possibly switch to the Monthly income method instead…

I have asked Immigration in Udon Thani and they informed me that when I apply for a 1-Year Extension the very first time I can only get an extension based on base the Non O E-Visa was issued on. However from the following second extension and so on I was informed it’s possible to switch from for example from a 1-Year Extension based on Marriage to based on Retirement. But as written above my plan is now to start based on Retirement and stay on that as my current planning ahead is at this very moment.

I know many expats who although married still use the 800K route, simply because it is less hassle than the 400K married visa

If I was married I would still go the retirement extensions route.

If the money in bank is a concern then use income method. 65k/month is hardly excessive amount to live off.

Added bonus is wife does not need to attend immigration + no home visit added rubbish etc

Ubon Rachathani. I was already on the 800k extension for many years when I married in 2020 and i just stay on it.

Like you say it's less hassle.

Indeed, not only less hassle for the foreigner but also less hassle for the Immigration office. This leads to some Immigration offices proposing the idea to foreigners over 50 currently using the marriage extension.

I previously used the 800k route up until covid . I was visiting my Mother in the U.K and was stuck there due to Thailand closing its border.

Then when they did open up again people on a Non O marriage extension were allowed back first.

I was told I could not return on my retirement extension, even though I had a valid re entry permit.

I had to apply for a Non O/A to get back in. Shortly after receiving the O/A they announced that the retirement extension could again be used.

I then realised how low we all are on the Thai authorities list of priorities.

Anyway since then due to caring for a elderly mother have been spending at least half my time in the U.K.

I do not get my state pension for another 8 years and am travelling back and fourth 4 - 5 times a year.

My savings are invested in a fixed account and I only have spare ฿ 400,000 so marriage route is my only option at the moment as want to get away from visa exempt and not have problems with my bank account ,driving licence renewal and entering many times per year.

Given this more detailed info a Non O marriage + annual extensions is best fit + multi reentry permit.

Come and go as often as you wish and only tie up the funds for few months.
