As of 25 July 2026, Thai Immigration's published extension criterion for a foreign husband married to a Thai national is either average income of at least THB 40,000 a month or at least THB 400,000 in a Thai commercial bank for the preceding 2 months. The relationship must be legal and genuine. A visa or status change and an annual extension are separate applications, with different forms and fees.
What the official rule covers
Immigration's family-of-Thai category covers a parent, spouse, child, adopted child or spouse's child, with additional conditions for each relationship. For a spouse, the published criterion says the relationship must exist both de jure and de facto: legally valid and genuine in practice. The national rule does not promise approval merely because a marriage certificate exists.
The rule and document list were re-checked on 25 July 2026 against Thai Immigration's published public handbook and the Immigration Bureau's Thai-wife extension checklist. No later official amendment changing the two financial thresholds was located.
Two stages that are often confused
Stage 1: a 90-day Non-O visa or status change inside Thailand
For an eligible applicant already in Thailand, the Immigration Bureau publishes a spouse-status-change checklist. As of 25 July 2026, it says the application must be filed with more than 15 days remaining and cannot be filed while on overstay. The form is TM.86 for a tourist or transit visa holder and TM.87 for an eligible visa-exempt entrant. The published application fee is THB 2,000. See the official Immigration checklist.
Stage 2: an extension based on Thai family
The later extension is an application to extend permission to stay, not a new embassy visa. As of 25 July 2026, Immigration public handbooks list the TM.7 extension fee as THB 1,900. The extension can be granted for no more than 1 year at a time; approval and the evidence accepted remain decisions for the handling office.
Financial evidence
| Published route | National criterion checked 25 July 2026 | Evidence point |
|---|---|---|
| Thai-bank deposit | At least THB 400,000 for the preceding 2 months | The account and bank documents must identify the applicant; the office may specify letter and update timing. |
| Average income | At least THB 40,000 a month | The Immigration status-change checklist describes embassy or consular certification with source evidence. Offices may publish additional evidence routes. |
The national marriage-extension criterion does not state that THB 400,000 must remain untouched all year. The previous version of this page incorrectly presented a year-round floor as a national rule; that claim was removed on 25 July 2026. A local office can still ask for transaction history or other evidence to test whether the funds and relationship are genuine.
Core documents
As verified 1 August 2026, the official lists centre on the following. They are not a guarantee that a particular office will ask for nothing else.
- TM.86 or TM.87 for an in-country status change, or TM.7 for an extension.
- Passport pages, a recent photograph and proof of the current permission to stay.
- Thai spouse's identity card and house registration.
- For a Thai-registered marriage, the applicable Kor Ror marriage registration and certificate records.
- For an overseas marriage, the foreign certificate plus Thai family-status registration and any translation/legalisation required by the official checklist.
- Financial evidence for the route used, in the applicant's name.
- Evidence that the relationship is genuine, including the official checklist's residence photographs and map requirements.
- Proof of the Section 38 accommodation notification when requested.
Royal Thai embassies set their own overseas Non-O document upload lists and local-currency fees. Thai Immigration offices also control appointment, copy, bank-letter and evidence details. This page does not average those differences into one universal checklist. For Pattaya, confirm the current list directly with Chonburi Immigration at Jomtien before the filing date.
Work is a separate permission
A marriage-based Non-O status does not itself authorise employment. A person may be eligible to seek a work permit under the labour rules, but the employer, job and permit must independently qualify. The earlier claim that this was the only Pattaya long-stay route compatible with a work permit was too broad and was removed on 25 July 2026.
Reporting and travel
- 90-day address reporting: a foreign national staying more than 90 consecutive days remains subject to TM.47 reporting. As checked 25 July 2026, Immigration's official online guide says an online request can be submitted within the 15 days before the due date.
- Accommodation reporting: Section 38/TM.30 is separate from the extension. Responsibility and re-filing facts depend on the accommodation and travel history; the handling office decides whether the receipt shown is sufficient.
- Leaving Thailand: an extension holder generally needs a re-entry permit to preserve the existing permission to stay. A border officer determines admission on return.
If the marriage ends
The legal and factual marriage is the basis for this extension. Divorce, annulment or the Thai spouse's death can therefore affect the permission to stay. No official national source located in this review publishes a universal grace period or promises that the current extension can simply run to its printed expiry date. Only the immigration office responsible for the file can issue the written determination on whether the existing permission ends, whether another statutory basis applies, and what application is available.
Processing time
No current official nationwide service standard for the full marriage-based decision was found on 25 July 2026. Marriage extensions can include an under-consideration period and verification of the household. Local reports about home visits or turnaround times are not presented here as rules. Jomtien decides its own queue and verification steps.
What changed on this review
- Replaced prescriptive recommendations with the published rule and decision points.
- Removed the unsupported year-round THB 400,000 claim and unverified Jomtien home-visit odds.
- Separated the THB 2,000 status-change fee from the THB 1,900 extension fee, both as checked 25 July 2026.
- Added the marriage-ending coverage and stated that no universal grace period was found.
Common questions
Related: Foreign marriage legalisation · Permanent-residence update · Jomtien Immigration · Marriage vs retirement
Does an overseas marriage count?
It may, but the official Immigration checklist requires the foreign marriage evidence and Thai family-status registration, with translation and legalisation where specified. The district office and Immigration decide whether the documents establish a valid marriage.
Is the THB 400,000 route a year-round minimum?
The national marriage-extension criterion checked 25 July 2026 says the deposit must have been held for the preceding 2 months. It does not publish a year-round THB 400,000 floor. The handling office can still examine the account and request additional evidence.
Can the holder work?
The Non-O status alone does not authorise work. Employment requires separate permission under the labour rules.
What happens after divorce?
The legal and genuine marriage is the extension basis. No universal official grace period was found in this review, so the responsible immigration office must determine the effect on the existing permission and any available change of basis.
