Can I apply for the marriage visa inside Thailand?

The extension of stay is always filed inside Thailand, at the immigration office for your province. The Non-O visa it builds on is normally issued abroad through the e-Visa system, and whether an existing stay can be converted in-country is a question for the immigration office, where a firm can check the current practice before you commit to a border run.

What documents prove the marriage?

For a marriage registered in Thailand, the Khor Ror 3 marriage certificate and the Khor Ror 2 registration record. For a marriage registered abroad, the foreign certificate plus the Thai record of family status, the Khor Ror 22. Officers also verify that the relationship is genuine in fact, not only on paper.

Does the 400,000 baht have to stay in the account?

The published criterion is that the deposit be maintained in the account for the past 2 months before filing. What happens to the balance between renewals is not stated on the published page, and a firm can advise on the practice at your office rather than leaving it to chance at the counter.

Can I work on a marriage visa?

The extension of stay based on marriage is permission to stay, not permission to work. Employment still requires a work permit under the working of aliens law, and the marriage route changes the visa side rather than the work permit side.

What happens to the visa if we divorce?

The extension rests on the marriage, so a divorce removes its basis. What that means for the remaining permission and the options from there depends on the circumstances, and a lawyer can set out the position before anything is filed with immigration.

What a marriage visa in Thailand actually is

There is no visa category called a marriage visa. What the phrase covers is a Non-Immigrant O visa granted on the basis of marriage to a Thai national, followed by a one year extension of stay issued inside Thailand by the Immigration Bureau, renewed annually. The visa gets you in; the extension is what lets you stay, and the extension is where the real requirements live.

The distinction matters because the two steps run through different agencies with different rules. The Non-O comes from a Thai embassy or consulate abroad through the e-Visa system. The extension comes from the immigration office for the province where you live, on criteria the Immigration Bureau publishes.

The financial test, and who it applies to

For a foreign husband of a Thai wife, Immigration Division 1 publishes the criteria in full: an average income of not less than 40,000 baht per month, or deposits of not less than 400,000 baht in a Thai bank account maintained for the past 2 months, or income and deposits together totalling not less than 400,000 baht for the year. The relationship must exist both legally and in fact, and officers verify both.

For a foreign wife of a Thai husband, the published criteria list the Non-O visa, proof of the relationship, and the requirement that the relationship be genuine in law and in fact. No financial figure appears in that list. Where the published pages leave a question open, the deciding voice is the immigration office handling the application, which is one reason applicants near the financial line bring in a firm before filing rather than after a refusal.

How the marriage route runs

Marry, and register the marriage
The extension rests on a marriage that exists in Thai law. A marriage registered in Thailand produces the Khor Ror 3 certificate and Khor Ror 2 registration record the extension application asks for; a foreign marriage needs recording in Thailand, work covered by marriage registration services.
Obtain the Non-O abroad21 working days
Thai embassies issue the Non-O through the e-Visa system; the Royal Thai Embassy in Singapore, for example, asks applicants to complete the application at least 21 working days before travel. A single entry Non-O is valid for 90 days from issue.
Build the financial evidence2 months
Where the deposit route is used, the 400,000 baht must sit in the account for the past 2 months before filing, so the seasoning period sets the earliest filing date.
File the extension
TM.7 with a recent photo, passport copies, the marriage documents, and the financial evidence, at the immigration office for your province. The fee is 1,900 baht, and each permission is granted for no more than one year.
Keep the stay alive
The extension renews annually on the same criteria. A re-entry permit protects the permission when you travel, and the 90 day address report continues throughout.

What continues after approval

An extension of stay is permission, not residency. It renews every year against the same financial and relationship tests, it dies if you leave Thailand without a re-entry permit, and the 90 day report runs for as long as the stay does. A change in the marriage changes the immigration position, and a lawyer can explain what a divorce or a spouse's death does to a stay built on this route.

When to bring in a firm

A straightforward renewal with strong finances needs little help. The cases that justify fees: first extensions, income earned abroad or in mixed forms that needs presenting against the published test, a marriage registered abroad that Thailand has not yet recorded, refusals and near-misses, and switches between visa categories. Firms handling this work sit under immigration law in Thailand, and the annual mechanics of staying are the territory of visa extension services.
