Thailand visa extensions, 90-day reporting and visa runs

Visa runs versus extensions

• For Non-Immigrant visas (O-A, O-X, O, LTR) extensions are done at immigration without crossing a border.
• For the DTV, each entry gives up to 180 days, usually extendable once. After that you leave and re-enter.
• On a 30-day visa-exempt entry you still have to leave and re-enter to stay longer, which is not sustainable as a way of living here, and repeated back-to-back entries are increasingly questioned.
• From 15 September 2026, most visa-exempt land-border entries are capped at two per calendar year.

How to apply for an annual extension

• Apply before your current permission expires, ideally with a buffer. The window opens up to 30 days before expiry.
• Use form TM.7, available at the office or to download in advance.
• Bring your passport with the visa page and entry stamp, your current visa documents, 2 to 4 passport photos and proof of the financial requirement, such as seasoned bank statements or an income letter.
• O-A and O-X holders must also show health insurance.
• Book ahead. Walk-ins near common renewal dates can mean long waits or a second visit.

Re-entry permits

Without a re-entry permit, an annual extension is cancelled when you exit Thailand. You can get a single or multiple re-entry permit, and you need to get it before any trip abroad.

90-day reporting

• Long-stay visa holders must confirm their address every 90 days. It is a confirmation, not a new application.
• You can report online, by post or in person.
• The 90-day clock restarts after each re-entry following international travel.
• A TM30 notification is also needed when you change address. Your landlord or accommodation provider normally files it, so keep proof.

Fines and risks

• Overstay: 500 THB per day, paid when you leave, capped at 20,000 THB
• Longer overstays, or being caught, can lead to detention and a re-entry ban
• A missed 90-day report brings a fine at your next in-person visit and a compliance mark that can draw scrutiny at renewal

Extensions when you live in Phuket

Use the Phuket immigration office for extensions and 90-day reports if your address is in Phuket, and check its current appointment and document rules before you go. If you are still choosing where to live, see our guides to the best areas for a long stay and long-term rentals.
