Thailand Re-Entry Permit (TM8): Complete 2026 Guide

If you hold a long-stay visa in Thailand and plan to travel abroad, there is one step you must not skip before you board: obtaining a re-entry permit. Without it, leaving Thailand immediately cancels your current visa or extension of stay. When you return, you are treated as a new arrival — and if your visa only allowed a single entry, you may not be admitted back at all. This guide explains what the re-entry permit is, who needs one, and how to get it before your next trip.

What a re-entry permit is and why it matters

Thailand issues most visas and extensions of stay on a single-entry basis by default. This means that the moment you physically leave Thai territory — even briefly, for a weekend across a land border or a short trip elsewhere in Asia — your current permission to stay is cancelled. The re-entry permit is the mechanism that prevents this. It signals to immigration that you intend to return, and it keeps your visa or extension of stay alive during your time abroad.

The permit is applied for using Form TM.8 and is stamped directly into your passport alongside your visa. It does not extend your permission to stay, does not change your visa category, and does not affect your 90-day reporting schedule. It has one job: preserving your existing permission during the gap between your departure and your return.

This distinction matters because people confuse a re-entry permit with other immigration steps. It is not a visa renewal. It is not a border run. It is simply a declaration in advance that you plan to come back, and it keeps your existing status intact while you are gone.

Who needs a re-entry permit

Anyone on a long-stay visa or an extension of stay who plans to leave Thailand temporarily needs one. This covers holders of:

• Non-Immigrant O (retirement or marriage-based) and Non-O-A (retirement) visas
• Non-Immigrant B (business) visas and work-permit holders
• Non-Immigrant ED (education) visas
• Long-Term Resident (LTR) visas — confirm the specific requirement for your sub-category with immigration
• Destination Thailand Visa (DTV)
• Any extension of stay, regardless of the underlying visa category

Short-term visitors on a visa exemption stamp or a single-entry tourist visa do not need a re-entry permit. Those permissions do not carry over on return in any case, and they simply re-enter on a new stamp or fresh visa. The re-entry permit is specifically for long-stay holders who have built up a current permission they want to protect.

Single or multiple: choosing the right type

There are two types of re-entry permit, and choosing the right one upfront saves time and cost:

• Single re-entry permit: allows you to leave and return to Thailand once. After you use it, the permit is spent. If you travel abroad again before your next visa renewal or extension, you need to apply for a new one.
• Multiple re-entry permit: allows unlimited departures and returns within your current permission period. It remains valid until your underlying visa or extension of stay expires, however many times you cross the border.

For people who travel occasionally — one or two trips a year — a single permit is the lower-cost option. For those who travel regularly, whether for work, family visits, or regional trips, a multiple permit is more practical and generally better value when you factor in the cost and hassle of applying repeatedly. Many long-stay expats on annual extensions take a multiple re-entry permit as a matter of course each time they renew, so it is already in their passport when they need it.

Fees are set by the Thai Immigration Bureau and are subject to change; the current amounts are posted at immigration offices. Applying at an airport counter typically costs slightly more than applying at an immigration office in advance. Always confirm the current fee when you apply, rather than relying on figures from any website including this one.

How and where to apply

You have two options:

At an immigration office before your trip — the recommended approach. Bring your documents, complete TM.8, pay the fee, and an officer stamps the permit into your passport. Processing is usually completed the same day. If a document is missing or needs correcting, you have time to fix it without the pressure of a departure looming.

At an international airport on the day of travel — available as a last resort if you forgot to apply in advance. Most major Thai international airports have an immigration desk where you can apply for a re-entry permit before you clear departure. This option exists, but fees are slightly higher, and if any document is missing there is no time for a fallback. Treat this as an emergency measure, not a default.

Retroactive application is not possible. The re-entry permit must be in your passport before you depart. Once you have left without one, your permission to stay has already been cancelled, and you will need to sort out your visa status on re-entry or before your next visit.

What you need and mistakes to avoid

Core documents for a TM.8 application:

• Your passport, open to the current visa or extension stamp and the most recent entry stamp
• Completed TM.8 form (available at the immigration office or downloadable in advance from the Immigration Bureau)
• A recent passport-sized photograph
• Photocopies of your passport photo page, current visa or extension stamp, and latest entry stamp

Common mistakes:

• Forgetting entirely: the most costly error. Your permission to stay is cancelled on departure, and recovering it means starting the visa process from scratch.
• Applying for a single permit when you travel regularly: you end up needing a new application before each trip, adding time, cost, and inconvenience throughout the year.
• Arriving at the airport with incomplete documents: a missing photograph or photocopy leaves you with almost no time before check-in closes.
• Confusing the re-entry permit with a visa extension: they are entirely separate. The permit preserves your existing stay; an extension adds time to it. You may need both, and they are applied for differently.
• Assuming land borders operate the same as airports: processes and availability at land crossings can differ from major airports — confirm before a land-border trip.

Thai immigration procedures and fees do change, and individual offices apply requirements slightly differently. The guidance here is accurate in principle for 2026, but always confirm the current process with your local immigration office before you travel.
