Reviewed 5 October 2026. We could not open an Immigration Bureau page, so thresholds come from embassy pages and law-firm guides. Immigration criteria are set by internal orders (Order 12/2568 of 23 January 2025 according to one law-firm site) and can differ by office.

A Non-Immigrant O visa gives a first stay of 90 days. Inside Thailand you can then apply for a 1-year extension of stay. For marriage to a Thai national sources report 400,000 THB in a Thai bank account or 40,000 THB monthly income. For retirement (age 50 or older) they report 800,000 THB in the bank, 65,000 THB monthly income, or a combination.
Which Non-O route fits you
| Route | Who | Money requirement reported |
|---|---|---|
| Marriage | Spouse of a Thai citizen, including same-sex spouses since the Marriage Equality Act took effect on 23 January 2025 | 400,000 THB in a Thai bank or 40,000 THB monthly income |
| Parent of a Thai child | Parents of a Thai national child | Typically 400,000 THB held for 3 months (one source); embassy London also lists 40,000 THB monthly |
| Retirement | Age 50 or older | 800,000 THB or 65,000 THB monthly or a combination. See retirement visa |
| Volunteer | Unpaid work for a registered organisation | Organisation letter; some embassies ask for a bank statement |
The embassy that issues the visa sets its own document list, so always read the page of the embassy you will use.
How the application works
- Get the 90-day visa. Apply at a Thai embassy or via the official Thai e-Visa portal. You can also convert from a visa-exempt or tourist stay at an immigration office in Thailand, but with the 30-day exemption your window for that is short.
- Prepare the money. Funds usually have to sit in a Thai bank account for 2 to 3 months before filing. One law-firm page says 2 months for the first application and 3 at renewal, an embassy says 3 before the application.
- Apply for the extension. In the last 30 days of the 90 days, file TM.7 at your immigration office. See visa extension.
- Get a re-entry permit before any trip abroad. See re-entry permit.
Where sources differ
Working on a Non-O
A retirement-based extension prohibits employment. Holders of a marriage-based visa may apply for a work permit separately, but the work permit is a different process with its own employer requirements. Read the work permit guide. Remote work for a foreign employer is a grey area that you should ask a Thai lawyer about.
Health insurance
Two sources we read state that the Non-O retirement extension in Thailand has no insurance requirement. The 1-year O-A visa applied for abroad does require cover of 3,000,000 THB or 100,000 USD according to Thai embassy pages. See expat health insurance.
