Extensions, re-entry permits and 90-day reporting

Extending your stay

Most long-stay routes are extended annually, and it is the address on record that decides which immigration office handles you. Apply in good time before the stamped date expires, bring originals plus photocopies, and expect to pay the fee in cash.

Requirements for each extension are worth checking a few weeks ahead: bank letters, insurance documents and photographs often have a validity window of their own.

90-day reporting

If you stay in Thailand continuously beyond 90 days, you must report your address every 90 days, online, by post or in person. The count restarts when you leave and re-enter the country. It is a simple administrative step, but missing it can mean a fine when you next deal with immigration.

If you travel

• Leaving Thailand without a re-entry permit generally ends the current permission to stay, even if the visa itself has time left on it.
• Single and multiple re-entry permits are applied for before departure, at the airport or at an immigration office.
• Keep your departure card, previous extension stamps and entry stamps together in one place. Losing them turns a ten-minute appointment into a long one.

TM30 and your address

The householder or possessor of the property is responsible for reporting a foreigner staying at the address. Hotels do this automatically; private landlords often do not, so ask early and keep a copy of what was filed. If you own the property, the responsibility is effectively yours.
