Marriage Visa for Thailand

Thinking about staying long-term in Thailand with your Thai partner?
Good news — Thailand does offer a visa option specifically for that situation and, in this blog post, we’re going to take a look at what most people call the marriage visa and what you’ll need for a successful application.

Hi, my name is Ben. For those who don’t know me, I’ve been living in Thailand for several years now, and during that time I’ve learned a lot about Thai visas — both from my own experiences and from friends who’ve been through the process. I like to share what I’ve learned, and today I’ll be breaking down everything I know about what’s commonly referred to as the marriage visa for Thailand.

In this blog post, we’ll cover:

Maintaining the marriage visa

Requirements can vary slightly depending on the immigration office, and they do change from time to time. So it’s always best to double-check with your local Thai embassy for the initial visa, and with your local immigration office for the extension.

What is the Marriage Visa?

When people talk about the “Marriage Visa” for Thailand, what they’re really referring to is the Non-Immigrant O Visa that’s been extended on the basis of being married to a Thai citizen. Technically, there’s no official visa category called a “Marriage Visa,” but it’s the term most people use — and honestly, it’s less of a mouthful and easier to understand.

In practice, this extension allows you to stay long-term in Thailand as long as you meet the requirements and renew it each year. So when someone says they’re on a “Marriage Visa,” what they probably mean is they’re on a one-year extension of the Non-Immigrant O Visa based on marriage to a Thai national.

The Non-Immigrant O visa itself is a multipurpose visa that can be granted for several reasons, including retirement, medical treatment, and family reasons such as being married to a Thai citizen. For marriage purposes, it typically begins as a 90-day visa, which can then be extended at your local immigration office for one year, so long as you meet all the criteria.

After your first extension, you can continue renewing it every year, provided you still meet the requirements and the immigration rules remain the same.

Marriage visa requirements

Let’s break this into two parts:
first, the requirements for the initial 90-day Non-Immigrant O visa that you apply for before entering Thailand, and then the requirements for the one-year extension you’ll apply for once you are in Thailand.

Requirements for application of Non-immigrant O Visa (Before Entering Thailand)
(Based on the London Thai Embassy — requirements may vary depending on the embassy or consulate.)

Passport or travel document
Photograph taken within the last six months
Proof of current residence
(e.g., utility bill showing name and address)
Financial evidence showing 40,000 THB monthly income or 400,000 THB in savings
Personal details of your family member in Thailand
(Thai spouse’s ID card or passport)
Proof of relationship, such as a marriage certificate

Some embassies may request additional documents such as bank statements, criminal background checks, or extra proof of relationship, so always check the specific requirements of the embassy where you will apply.

Requirements for the One-Year Extension (Inside Thailand)

Passport or travel document
(plus photocopies of relevant pages including the photo page, visa, and most recent entry stamp)
Completed Application Form (TM.7)
Recent passport-sized photo
Marriage certificate (Kor Ror 3) and marriage registration extract (Kor Ror 2)
These often need to be certified recently (within 30 days)
If married abroad, documents must be translated and legalised
House registration book (Tabien Baan) of where you will be living
Photos of you and your spouse together
(inside the home, outside with house number, and sometimes with family members, ask for specific details from your local immigration office)
House map showing the location of your home
Financial evidence showing 40,000 THB monthly income, or
400,000 THB in a Thai bank account (subject to seasoning and maintenance rules)

After submitting your application, immigration officers may conduct a home visit to confirm that you and your partner live together and that your relationship appears genuine. This doesn’t happen to everyone, but it is fairly common, especially outside of Bangkok.

Visa Costs and Financial Requirements

Here’s a breakdown of the main costs involved in obtaining and maintaining a marriage-based visa in Thailand.

Visa Fees

90-day Single-Entry Non-Immigrant O Visa: 2,000 THB
(This is applied for at a Thai embassy or consulate before entering Thailand. The fee may vary slightly depending on the country you apply in.)
1-year Extension Based on Marriage: 1,900 THB
(This fee is paid at your local immigration office in Thailand.)
Re-Entry Permit (optional but often necessary)
Single re-entry: 1,000 THB
Multiple re-entry: 3,800 THB
(A re-entry permit is required if you want to leave Thailand without cancelling your extension.)

Financial Requirements
To qualify for the marriage-based extension, you must meet one of the following financial conditions:

Option 1 — 400,000 THB in a Thai Bank Account

Must be deposited at least two months before applying
Must remain at 400,000 THB for the first three months after approval
After that, it must not drop below 200,000 THB for the rest of the year

Option 2 — 40,000 THB Monthly Income

Note: Some embassies no longer issue income letters, and some immigration offices no longer accept them, so the 400,000 THB method is often the most reliable.

Marriage Visa Warnings and Considerations

I always like to include a section like this when talking about visas, because situations can change, rules can be interpreted differently, and it’s important to understand the potential risks before making long-term plans.

Financial Requirements Must Be Maintained
If you choose the 400,000 THB method, remember that immigration expects you to maintain the funds according to strict rules:

The full 400,000 THB must be in your Thai bank account for at least 2 months before applying for the extension.
After your extension is approved, the balance must remain at 400,000 THB for the first 3 months.
For the rest of the year, the balance must not drop below 200,000 THB.
If it does, you risk your next extension being refused.

This catches many people out, so it’s worth planning your finances carefully.

If the Relationship Ends, the Visa Ends
It’s an unfortunate reality, but if a marriage legally ends, the marriage-based extension is no longer valid. Immigration typically gives you 7–14 days to arrange a different visa type or leave the country.
This doesn’t mean you should worry unnecessarily, but it’s important to understand the consequences.

The Visa Does Not Automatically Allow You to Work
A marriage visa makes it possible to get a work permit, but it does not give you the right to work on its own.
You must still apply for and be issued a work permit before you can work legally in Thailand. Working without a permit can lead to fines, visa cancellation, or other penalties.

How to Apply – Step-by-Step Process

Now that we’ve covered the potential challenges, if you still feel the marriage visa is the right option for you, let’s go through the actual application process. Here is a simple step-by-step guide to how it works from start to finish:

Step 1 — Apply for the Non-Immigrant O Visa (90 days)
Your first step is to apply for a Non-Immigrant O visa at a Thai embassy or consulate outside Thailand.
You’ll need to provide proof of your marriage, financial evidence, photos, and basic supporting documents. Once approved, you’ll receive a 90-day entry visa.

Step 2 — Enter Thailand and Prepare Your Extension Documents
After arriving in Thailand, begin gathering all the documents required for your one-year extension.
This includes certified marriage documents, your spouse’s ID and house book, TM30, house map, photos together, and financial proof (including a bank letter issued on the day of your application).

Step 3 — Apply for the One-Year Extension at Your Local Immigration Office
Visit your local immigration office with your Thai spouse and submit all your paperwork.
You’ll have your documents checked, answer a few basic questions, and pay the 1,900 THB fee.
Some offices may ask for additional photos or information, and a home visit is possible—especially for first-time applications.

Step 4 — Receive Your Extension
Most immigration offices will give you a 30-day “consideration” stamp after you submit your application. During this period, immigration will review your documents, verify your information, and may conduct a home visit.
Once your application is approved, you’ll receive the full one-year extension stamped in your passport.

Step 5 — Maintain the Visa
After approval, you must keep your visa in good standing.
This means reporting your address every 90 days, keeping your financial balance above the required minimum, updating your TM30 if you move, and obtaining a re-entry permit before leaving Thailand.

Maintaining the Visa

Once your one-year extension is approved, there are a few responsibilities you need to keep on top of throughout the year to avoid problems at your next renewal.

90-Day Reporting:
Every 90 days you must report your current address to immigration.
This can be done online, in person, or by mail. Missing a report isn’t the end of the world, but it may lead to a fine and can complicate future renewals.
Keep in mind that the 90-day count resets every time you leave and re-enter Thailand.

Re-Entry Permits:
If you plan to leave Thailand at any time, you must obtain a re-entry permit before you travel. Without one, your entire one-year extension is automatically cancelled the moment you leave the country.
A single re-entry permit costs 1,000 THB, and a multiple re-entry permit is 3,800 THB.

Financial Maintenance:
If you are using the 400,000 THB method, the money must remain untouched for the first three months after your extension is approved.
After that, your account must not drop below 200,000 THB for the rest of the year.
Many people are caught out by this at renewal, so it’s important to manage your finances carefully.

TM30 / Change of Address:
If you move house, you or your landlord must update the TM30.
Immigration may refuse future extensions if your address is not properly registered.

These are the main things to stay on top of each year.
As long as you handle 90-day reporting, financial requirements, re-entry permits, and TM30 updates correctly, maintaining the marriage visa is generally straightforward.
