How to Apply for a Marriage Visa in Thailand

The marriage visa Thailand route, formally known as the Thailand Non-Immigrant O visa, allows foreign nationals who are legally married to a Thai citizen to live in Thailand on a renewable, long-stay basis. The core process is to obtain a 90-day Non-O — either as an e-visa from a Thai embassy abroad, or by converting your existing stay inside Thailand if your funds are already in a Thai bank account — and then apply for a one-year extension at your local immigration office. Handled correctly, it is one of the most stable long-term residency pathways available in the country.

What Exactly Is the Thailand Marriage Visa?

The "marriage visa" is not a standalone visa label in Thai immigration law. It is a Non-Immigrant O visa issued on the basis of marriage to a Thai national. The "O" stands for "Other," covering several relationship-based categories, with spousal status being the most common. The visa grants a 90-day entry or stay initially, which is then converted into a one-year extension of stay at an immigration office inside Thailand.

This distinction matters practically: you get the 90 days on the visa, but you live on the extension. Confusing the two is a common source of overstay errors.

What Are the Core Non-O Visa Requirements Thailand Enforces?

Thai immigration sets three eligibility pillars for the spousal Non-O:

• Legal marriage to a Thai national: Recognised under Thai law, with a registered marriage certificate. Engagement or an intention to marry does not qualify, and two foreigners marrying each other does not qualify. Same-sex couples are eligible once legally married.
• Financial qualification: Must meet one of the options below.
• Clean criminal record: No serious criminal convictions in your home country or Thailand.

Financial Requirements: Your Three Options

The key insight is that the 40,000 THB monthly option is a Thai employment route, not an overseas one. A pension statement, an employer income letter, or a tax cover letter without the PND 91 does not satisfy it. If your income is foreign-sourced and you do not hold a Thai work permit, your realistic routes are the 400,000 THB deposit or the embassy-verified foreign income letter. There is no combined income-plus-savings route for the marriage Non-O.

One exemption to check before anything else: where the Thai national is male and the foreign spouse is female, the 400,000 THB savings requirement does not apply at all - on either the in-country conversion or the e-visa path. A foreign woman married to a Thai man does not need to meet the financial test, and can convert to a Non-O inside Thailand without showing 400,000 THB.

How Long the 400,000 THB Must Be Seasoned

Quoting the wrong seasoning window is one of the most common causes of rejection, because the window is different at every stage:

If you arrive on an e-visa Non-O rather than converting in-country, open your Thai bank account and deposit the full 400,000 THB within the first 30 days after entry. The two-month seasoning clock for the extension only starts once the full balance is actually in the Thai account.

Do You Have to Leave Thailand to Get the Non-O?

Usually not. This is the single most persistent myth about the marriage visa. If your 400,000 THB is already sitting in a Thai bank account, you can convert your current stay into a 90-day Non-O without leaving the country - and that includes people who entered on a tourist visa or on a visa exemption.

Where the funds sit is what decides the route:

• 400,000 THB already in a Thai bank → in-country conversion, no exit required
• 400,000 THB in an overseas bank → apply for the Non-O e-visa from a Thai embassy abroad, then transfer the funds after you arrive

Who Can Convert Inside Thailand

The 21-day rule matters. If your current permission to stay has fewer than 21 days left when you file, immigration will not accept the conversion. In that case you either exit and re-enter to reset the clock, or apply for the Non-O e-visa from abroad instead.

One practical trade-off to plan for: the in-country conversion needs a noticeably larger document pack and roughly three immigration visits across the conversion and the extension, whereas the e-visa route needs a shorter pack and one immigration visit later for the extension.

What Documents Do You Need for a Marriage Visa Thailand Application?

The marriage visa Thailand documents list is more extensive than most applicants expect, because it requires proof from both the foreign applicant and the Thai spouse. Missing even one item will result in rejection at the immigration counter. Your passport must have more than 18 months of validity remaining when you start the 90-day application - visa validity is capped at passport expiry, and immigration needs the headroom to stamp a full one-year extension later. If you have 18 months or less, renew the passport first.

In-Country Conversion to the 90-Day Non-O (400,000 THB in a Thai bank)

• Passport biodata page, valid more than 18 months
• ID-style headshot photograph
• Marriage certificate
• Thai spouse's national ID card
• Thai spouse's household registration (Tabian Baan)
• Single Status Certificate, confirming you were legally free to marry
• Bank statement showing 400,000 THB maintained over the last 3 months, issued the same day as the application
• Bank amount certification, also issued the same day
• Copy of the bank passbook, with the original on the submission date
• Rental agreement plus the landlord's documents (ID card, house registration, title deed)
• Proof of rental payments for the past 3 months
• Photographs of you and your Thai spouse inside the property (all rooms) and outside showing the address
• TM30 residence notification

E-Visa Non-O from Abroad (400,000 THB in an overseas bank)

• Passport biodata page, valid more than 18 months
• ID-style headshot photograph
• Copies of all Thailand visas and stamps
• Intended address in Thailand as an official PDF - screenshots are not accepted
• Last 6 months' bank statement with an ending balance above 400,000 THB or the foreign currency equivalent
• Proof of address in the submission country (hotel booking, national ID, driver's licence)
• Marriage certificate
• Thai spouse's national ID card
• Thai spouse's household registration (Tabian Baan)

One-Year Extension at Immigration

• Completed TM.7 extension application form with a recent photograph attached
• Copies of the passport biodata page, most recent entry stamp, initial visa, and latest visa or extension stamp
• Copy of the TM.6 arrival/departure card, if one was issued
• Copy of the TM30 address report and the latest 90-day report, if applicable
• If you married in Thailand: Marriage Certificate (Kor Ror 3) and Marriage Registration Record (Kor Ror 2), obtainable from an Amphur or Khet office
• If you married abroad: the foreign marriage certificate and the Thai Record of Family Status (Kor Ror 22) - this replaces Kor Ror 2, and bringing Kor Ror 2 instead is a frequent error
• Thai spouse's national ID and household registration
• Savings route: bank-certified statement showing 400,000 THB maintained for the last 2 months, plus the credit advice if the funds were transferred from overseas
• Six photographs of you and your Thai spouse in the property (all rooms) and outside showing the address
• Work-permit route instead of the bank documents: work permit, PND 91, and PND 1 filings for the last 3 months

If your marriage was registered abroad, the certificate must be legalised (apostilled or consular-certified) and officially translated into Thai. Names on every document must match your passport exactly.

How Do You Apply Step by Step?

There are two paths to the 90-day Non-O, and both end at the same place: a one-year extension of stay granted inside Thailand.

Route A - Converting Inside Thailand (funds already in a Thai bank)

1. Step 1 - Check that your current stay qualifies. A tourist visa or visa-exemption entry with at least 21 days remaining works. A DTV, Non-ED, another Non-O category, or an APEC/ABTC 90-day entry does not.
2. Step 2 - Season the funds. 400,000 THB held in a Thai bank account in your own name across the 3 months before filing. The bank statement and bank certification must be issued on the same day you file, because immigration wants confirmation the balance still exists that morning.
3. Step 3 - Assemble the conversion pack from the checklist above, including the rental documents, residence photographs and TM30. This pack is substantially larger than the e-visa one.
4. Step 4 - File at immigration and receive the 90-day Non-O stamp.
5. Step 5 - File the one-year extension up to 45 days before that 90-day stamp expires, with the 400,000 THB maintained for the 2 months beforehand.

Route B - Applying by E-Visa from Abroad (funds in an overseas bank)

1. Step 1 - Apply for a Non-Immigrant O e-visa at the Thai embassy or consulate in your home country or a country where you hold legal residency, with your marriage certificate and financial proof. This is normally a 90-day single-entry Non-O; a multiple-entry version is not commonly issued for this category.
2. Step 2 - Enter Thailand within 90 days of issuance. You then have a 90-day window to complete the extension application.
3. Step 3 - Open a Thai bank account and deposit 400,000 THB within the first 30 days after entry. This is the step most applicants underestimate. The two-month seasoning clock does not start until the full balance is in the account, so plan your timeline backwards from your stamp expiry date.
4. Step 4 - Prepare the full extension package as listed above, including the TM.7 form and the correct Kor Ror documents for where you married.
5. Step 5 - Apply at your local immigration office, up to 45 days before your 90-day stamp expires. Both you and your Thai spouse typically need to appear in person. Officers may conduct a brief interview and, in some provinces, a home visit. Requirements vary slightly by province, so confirm with your specific office beforehand.
6. Step 6 - Receive your one-year extension stamp. You must also report your address to immigration every 90 days, and obtain a re-entry permit before any international travel - the marriage Non-O is typically single-entry, and leaving without one voids your permission to stay.

What Are the Most Common Mistakes That Lead to Rejection?

Document errors, not ineligibility, are the primary reason spousal Non-O extensions are denied. The most frequent issues include:

• Assuming you must exit Thailand and apply at an embassy, when your 400,000 THB is already in a Thai bank and an in-country conversion was available
• Filing an in-country conversion with fewer than 21 days left on the current stay permit
• Bank funds not seasoned long enough for the stage you are at - 3 months for the conversion, 2 months for the first extension, 3 months for each renewal
• A conversion bank statement or certification that was not issued on the day of filing
• Bringing Kor Ror 2 to the extension when the marriage was registered abroad, where Kor Ror 22 is required instead
• Foreign marriage certificates that are not apostilled or certified, or not translated into Thai
• Passbook copies showing the balance dropped below 400,000 THB at any point during the seasoning period
• TM.7 forms that are incorrectly filled out or unsigned
• Applying at the wrong immigration office (jurisdiction is determined by your registered address)
• Attempting the 40,000 THB income route on a foreign pension or an overseas employer's letter, without a Thai work permit and the PND 91 and PND 1 filings to back it
• Spouse not present on the day of the appointment
• Starting the 90-day application with 18 months or less of passport validity, which caps the extension short

Does a Marriage Visa Let You Work in Thailand?

Not on its own. A marriage Non-O does not authorise work. You still need a separate, employer-sponsored work permit, exactly as you would on any other visa. Say this to yourself before you accept a job offer on the strength of the visa alone.

What the marriage Non-O does change is who controls your right to stay. On a Non-B, the visa and the work permit are tied to each other: if the job ends, the employer cancels the visa at Immigration, the cancellation date can be set up to 21 days ahead, and you must leave Thailand on or before that date. On a marriage Non-O, you can cancel the work permit and keep the visa, as long as you still meet the financial test set out above.

The second difference sits on the employer's side. A company sponsoring a work permit for a marriage Non-O holder faces a 2:1 Thai-to-foreign staff ratio and 1,000,000 THB in registered capital, rather than the 4:1 ratio and 2,000,000 THB a Non-B sponsor has to meet. A small Thai company that cannot legally hire you on a Non-B can often hire you on a Non-O.

How Do You Renew a Marriage Visa in Thailand?

Annual renewal follows a similar document list to the initial extension, with one important difference: on the savings route the 400,000 THB must be maintained for the last 3 months before filing, not 2. File as early as 45 days before your current extension expires. Officers may also request evidence that the marriage is genuine and ongoing, such as rental payment proof, residence photographs, shared utility bills or an updated household registration. Do not wait until the last week of your current extension to start preparing; begin gathering documents at least 6 weeks out.

Can You Get a Work Permit on a Non-O Visa?

Only on two bases. A Non-Immigrant O held on the basis of marriage to a Thai spouse, or as the parent of a Thai child, allows the holder to apply for a Thai work permit. Every other Non-O category is not allowed to get one — that includes Non-O retirement, guardian of a foreign child, dependant of a Non-B work permit holder, and dependant of a retirement visa holder. The Non-OA and Non-OX retirement visas do not allow a work permit either.

On the two categories that do qualify, the visa and the work permit are independent of each other. The marriage or parent-of-Thai-child visa only allows the holder to apply for a work permit; it does not depend on one. If the holder stops working, they can cancel the work permit and keep the visa, provided they still meet that visa's financial requirement — typically 400,000 THB in savings at extension.

The employer requirements are lighter than on a Non-Immigrant B. A company sponsoring a work permit for a marriage or parent-of-Thai-child visa holder needs a ratio of 2 Thai employees per foreigner rather than 4:1, and 1,000,000 THB in registered share capital rather than 2,000,000 THB.

There is also an alternative to the savings test at extension: a valid Thai work permit plus 40,000 THB per month in income, evidenced with the PND 91 annual personal income tax return and PND 1 monthly withholding returns. The work permit alone is not sufficient — immigration needs the tax filings to verify the income.

As with any Thai work permit, it is tied to a single employer: the holder may only work for that one Thai company while the permit is active.
