A Thailand marriage visa can allow the foreign spouse of a Thai citizen to stay in Thailand on a family basis. The term usually refers to a Non-Immigrant O visa, a change to Non-O status inside Thailand, or a one-year extension of stay based on marriage. These are related procedures, but they are not the same application.
This guide explains the main routes, financial requirements, supporting documents, application process and continuing obligations. Next Step Hua Hin can assess your current status, prepare a case-specific checklist and support you through the process in Hua Hin.

Thailand marriage visa: quick facts
- Who it is for: a foreign national who is legally married to a Thai citizen and can prove a genuine continuing relationship.
- Common long-stay route: Non-Immigrant O status followed by an extension of stay based on marriage.
- Common financial figures: THB 400,000 in a qualifying Thai bank account or qualifying income averaging at least THB 40,000 per month, subject to the route and accepted evidence.
- Official extension fee: THB 1,900 under the published Immigration checklist. Visa and document-processing fees are separate and can vary.
- Validity: a Non-O entry and a one-year extension are different permissions. Always read the “admitted until” date and conditions in your passport.
- Work: marriage-based immigration status is not a work permit. Work authorisation must be considered separately.
What does “Thailand marriage visa” mean?
“Marriage visa” is a convenient everyday term, not the name of one single immigration product. A person may be referring to one of several different procedures:
| Route | What it does | Where it is normally handled |
|---|---|---|
| Non-Immigrant O visa for a Thai spouse | Provides an initial family-based entry or stay, commonly up to 90 days for a single-entry visa. | A Thai embassy or consulate through the applicable e-Visa or local mission process. |
| Change to Non-O status in Thailand | May allow an eligible person already in Thailand to obtain Non-O status without first leaving, provided the current entry, remaining stay and evidence meet the requirements. | The responsible Thai Immigration office. |
| One-year extension based on marriage | Extends permission to stay on the basis of a legal and genuine marriage to a Thai citizen. It is not a new entry visa. | The Immigration office responsible for the applicant’s residence. |
| 60-day family-visit extension | A shorter extension for an eligible person visiting a Thai spouse or Thai child. It is not a substitute for a one-year marriage extension. | Thai Immigration. |
The correct route depends on where you are now, how you entered Thailand, how much permitted stay remains, where the marriage was registered and whether your evidence is ready. If you only need a short family visit, read our separate 60-day family extension guide. If you are applying from abroad, our Thailand e-Visa guide explains the online process and travel considerations.
Who may qualify for a marriage-based stay?
The central requirement is a legally recognised marriage to a Thai citizen. Immigration must be satisfied that the marriage exists both legally and in practice. A wedding ceremony, engagement or long-term partnership without legal marriage registration is not enough by itself.
A typical applicant will need to show:
- a valid passport and an immigration status from which the intended application can be made;
- a valid marriage and reliable civil-status records;
- proof that the Thai spouse is a Thai national;
- a genuine, continuing relationship and shared household evidence;
- the financial evidence required for the chosen procedure;
- a current residential address and supporting notifications or records; and
- enough remaining permitted stay to complete the intended process.
Official Thai checklists have historically used gendered wording, especially when describing the financial test for a foreign husband married to a Thai wife. Couples whose circumstances do not match that wording should obtain a current case-specific assessment rather than assume that an online checklist applies unchanged.
Financial requirements for a one-year marriage extension
For the commonly used extension route described in the Immigration Bureau’s published checklist, the two principal financial methods are:
- Thai bank deposit: at least THB 400,000 in a qualifying account at a bank in Thailand, held for the required period; or
- Monthly income: qualifying income averaging at least THB 40,000 per month, proved in a form accepted for the application.
The THB 400,000 bank method
The central published extension checklist states that the funds should have remained in the Thai bank account for the preceding two months. It also asks for a bank confirmation letter and an updated bank book showing the required balance. Account ownership, account type, timing, transaction history and same-day updates can all matter.
Do not wait until the last moment to move money or open an account. If banking is part of your plan, ask us to review the timing first and see our Thai bank-account assistance.
The THB 40,000 monthly-income method
The official figure alone does not establish that your evidence will be accepted. The source of the income, employment and tax records, pension evidence, transfers, embassy practices and the local office’s documentary requirements can affect how income is proved. Ask for the current evidence list before relying on this route.
Can income and savings be combined?
Some published official material refers to a combined annual income and deposit total, but applicants should not assume that a combination method will be accepted in every marriage-based case or at every office. Confirm the method with the responsible office before arranging funds.
Typical documents and evidence
The exact list depends on the route and the Immigration office. A one-year extension based on marriage commonly involves documents from both spouses.
From the foreign spouse
- Passport and signed copies of relevant identity, visa, entry and permission-to-stay pages
- Completed application form, normally TM.7 for an extension, with the required photograph
- Current address evidence and any relevant TM30 or 90-day reporting record
- Bank letter, updated passbook, income evidence or other accepted financial documents
- Previous marriage or divorce records where relevant
From the Thai spouse
- Thai identity card
- Thai house registration, or Tabien Baan
- Marriage records and any updated civil-registration evidence requested
- Name-change, divorce or other civil documents where relevant
Relationship and residence evidence
- Marriage certificate and marriage-registration record
- Photographs of the couple together at the residence, including inside and outside views where requested
- A map showing the home’s location
- Lease, property records, landlord documents or other proof of the current shared address
- Additional evidence requested to resolve names, addresses or relationship history
Bring originals as well as the required signed copies. Keep spelling, transliteration, dates and addresses consistent across passports, Thai records, bank records and application forms. The Immigration Bureau’s published checklist expressly allows officers to request additional evidence.
If the marriage was registered outside Thailand
An overseas marriage may support a Thai immigration application, but the foreign certificate is not always ready for immediate use. Depending on the issuing country and intended procedure, the document may require authentication, Thai translation, legalisation and registration of family status at a Thai district office. A Khor Ror 22 family-status record may be required.
The sequence matters. Do not pay for a translation before confirming which version of the document must be authenticated and which authority must certify it. Read our guides to translation and legalisation and getting married in Thailand.
How the marriage visa or extension process works
- Identify the correct procedure. Establish your current entry status, permission-to-stay date, location, marriage-registration country and intended length of stay.
- Check the timing. Confirm that enough permitted stay remains for an overseas application, an in-country change of status or an extension. Do not rely on an appointment date alone.
- Choose and prepare the financial route. Allow enough time for any bank-balance holding period and obtain evidence in the form and date range requested.
- Align the civil and address records. Resolve inconsistent names, addresses, marriage records, translations, legalisation or TM30 issues before submission.
- Prepare the application pack. Use the current form and arrange originals, signed copies, photographs, map, bank records and spouse documents in a clear order.
- Attend the responsible office. Both spouses are commonly expected to attend and may be interviewed. Follow the specific instructions for the office handling your address.
- Follow the under-consideration instructions. Keep the receipt, note the return date, remain reachable and provide any additional evidence promptly.
- Check the passport after approval. Confirm the category, dates, conditions and next reporting or travel steps before leaving the office.
In Hua Hin, annual extensions and more complex matters are generally handled at the main Immigration office rather than a limited-service location. Check our current Hua Hin Immigration office guide before travelling.
Timing, government fees and planning
The published government fee for an extension of temporary stay is THB 1,900. A visa obtained from a Thai embassy or consulate, an in-country change of status, a re-entry permit, translations, legalisation, bank documents, photographs and professional assistance may involve separate fees.
Processing time is not one fixed period. It depends on the route, the responsible authority, document readiness, the remaining permitted stay and whether additional checks are required. Start early enough to correct records and satisfy the financial timing rules. If your stay expires soon, send us the exact date immediately.
The under-consideration period and home visits
A marriage-based extension may first receive an “under consideration” stamp while Immigration completes its review. The stamp’s return date and instructions are controlling. This stage is not the same as final approval.
Immigration may interview the couple, ask for further records, contact witnesses or conduct a home visit to verify the declared residence and relationship. Keep the address accurate, remain reachable and do not stage or alter evidence. If travel becomes necessary, obtain advice before making bookings or leaving Thailand.
What happens after approval?
A marriage-based extension does not remove other immigration obligations. Depending on your circumstances, you may still need to manage:
- 90-day reporting: this is separate from the expiry of the extension.
- TM30 address notification: accommodation and return-to-address circumstances can affect what must be reported.
- Re-entry permission: leaving Thailand without protecting an extension can cause the permission to end.
- Annual renewal: the extension must normally be renewed while the applicant continues to meet the requirements.
- Work authorisation: a separate work permit or other permission may be required before working.
- Changes in circumstances: separation, divorce, a new address, passport replacement or changes to financial evidence should be assessed promptly.

Marriage visa or retirement route?
A person aged 50 or over may be able to consider both marriage- and retirement-based options. The headline financial requirement for marriage is commonly lower, but that does not automatically make it the easier or better route.
| Consideration | Marriage-based route | Retirement-based route |
|---|---|---|
| Core basis | Legal and genuine marriage to a Thai citizen | Age and the requirements of the selected retirement category |
| Common financial headline | THB 400,000 deposit or THB 40,000 monthly income for the commonly used extension route | Often a higher financial threshold, depending on the exact retirement route |
| Relationship evidence | Central to the application | Not the basis of the application |
| Spouse participation and checks | Commonly required; an interview or home verification may occur | Normally assessed primarily on the applicant’s own eligibility |
| Work | Immigration status and work authorisation remain separate | Retirement status is generally unsuitable for employment |
The right choice depends on more than the bank figure. Consider document burden, employment plans, travel, renewal strategy and how a change in family circumstances could affect status. See our comparison of Thai retirement routes, then ask us to compare the options for your case.
Common marriage visa mistakes
- Confusing a 90-day Non-O entry with a one-year extension
- Counting from visa validity instead of the passport’s permission-to-stay date
- Moving funds too late or using the wrong account structure
- Assuming any overseas income evidence will automatically be accepted
- Submitting an overseas marriage certificate without the required authentication, translation, legalisation or Thai registration
- Using an old or incomplete marriage-registration record
- Letting names, addresses or transliterations differ across documents without explanation
- Arriving without the Thai spouse, originals, required photographs or address evidence
- Leaving Thailand without checking re-entry requirements
- Assuming marriage-based immigration status gives automatic permission to work
- Copying another couple’s checklist when their nationality, office, entry status or marriage records are different
Frequently asked questions
Is a Thailand marriage visa valid for one year?
A one-year permission commonly refers to an extension of stay based on marriage. An initial single-entry Non-Immigrant O visa commonly supports a shorter initial stay. Check the exact visa, entry stamp and extension in your passport rather than relying on the general label “marriage visa.”
Do I need THB 400,000 in a Thai bank?
The bank-deposit route commonly requires at least THB 400,000 in a qualifying Thai account for the required period. A qualifying monthly-income route may be available instead. The evidence and timing must be confirmed for your case.
Does my Thai spouse need to attend?
Both spouses are commonly required to attend a marriage-based application or interview. Follow the current instructions of the responsible office and bring the Thai spouse’s original identity and civil documents.
Can I apply if we married outside Thailand?
Potentially, yes. The overseas marriage must be legally valid and may need authentication, Thai translation, legalisation and family-status registration in Thailand before it is ready for the immigration procedure.
Can I change from visa exemption or a tourist visa inside Thailand?
An in-country change to Non-O status may be possible in eligible circumstances, but it is not automatic. Your current entry, remaining permitted stay, documents and local filing requirements determine whether the route is available.
Can I work on a marriage visa?
Marriage-based permission to stay is not itself permission to work. Depending on the activity, employer and circumstances, a separate work permit or other authorisation may be required before work begins.
Can I leave Thailand during the extension?
Travel may be possible, but an appropriate re-entry permit may be needed to preserve an existing extension. Travel during an under-consideration period can create additional issues. Check before booking or departing.
Will Immigration visit our home?
A home visit or other relationship and residence checks may form part of a marriage-based case. Requirements and practice vary. Keep your declared address accurate and your supporting evidence genuine.
Do I need to renew every year?
A one-year extension normally requires a new application before it expires, with current evidence showing that the requirements continue to be met. It does not renew automatically.
What happens after divorce or separation?
A change in the relationship can affect the basis of stay. Do not wait until the next renewal. Obtain case-specific advice promptly about the current permission and any alternative route.
Can Next Step guarantee approval?
No. Only the responsible Thai authority can decide an application. Next Step Hua Hin can assess the route, identify evidence problems, prepare the paperwork and support the process.
