Of everything that can go wrong with a long-stay visa in Thailand, forgetting a re-entry permit is one of the most avoidable — and one of the most damaging. It’s a small stamp in your passport that costs a modest fee and takes a few minutes to arrange. Skip it, and a routine weekend trip abroad can instantly cancel a visa extension you spent months qualifying for, forcing you to start the entire application process again from scratch.
This guide covers exactly what a re-entry permit is, who needs one, how to get one, what it costs, and how to avoid the single most common and most costly mistake long-term residents make in Thailand.

1. What a re-entry permit actually does
A re-entry permit is an official stamp placed in your passport by Thai Immigration that allows you to leave Thailand temporarily and return under your existing visa and extension of stay — without that extension being cancelled the moment you exit the country.
It’s easy to misunderstand what this stamp is actually doing. It isn’t a new visa, and it doesn’t add any extra time to your stay. It simply preserves the permission-to-stay you already hold, protecting it against the automatic cancellation that would otherwise happen the instant you cross the border.
2. Why it exists: the core problem it solves
Under Thai immigration rules, an extension of stay granted inside Thailand — for retirement, marriage, business, education, or most other non-immigrant categories — is tied to a single, continuous period of residence. The moment you physically leave the country, that extension is treated as used up, regardless of the expiry date printed in your passport. Without a re-entry permit, “leaving Thailand for the weekend” and “ending your visa early” are, immigration-wise, the same event.
The re-entry permit is the specific mechanism that breaks that link — it tells immigration, in advance, that this particular departure is temporary and that your existing status should remain intact when you come back.
3. Who needs one
You need a re-entry permit if you hold an extension of stay granted inside Thailand and plan to leave the country before that extension expires. This covers the situation most long-term residents are actually in:
- Retirement extensions (Non-O/O-A)
- Marriage extensions (Non-O)
- Business/work extensions (Non-B)
- Education extensions (Non-ED)
- Most other extensions of stay obtained from a Thai immigration office rather than from a visa issued abroad
4. Who doesn’t need one
You generally don’t need a separate re-entry permit if:
- You genuinely hold a multiple-entry visa that hasn’t yet been converted into an in-country extension — for example, a multiple-entry Non-Immigrant O/O-A used within its original validity, or the DTV, which is issued as a multiple-entry visa in its own right
- You’re leaving Thailand permanently and don’t intend to return under the same visa status
5. Single vs multiple re-entry permits
| Type | Typical fee | Covers | Best for |
|---|---|---|---|
| Single re-entry permit | ~1,000 THB | One departure and return | A single planned trip abroad |
| Multiple re-entry permit | ~3,800 THB | Unlimited departures and returns for the remaining validity of your current extension | Anyone travelling more than twice before their next renewal |
As a simple rule of thumb: if you know you’ll be making two or more trips before your next extension renewal, the multiple permit is almost always better value than paying for single permits repeatedly. Both permit types remain valid only up to your current “admitted until” date — they preserve your existing stay, they don’t extend it.
6. Where to apply: immigration office vs airport
At a Thai immigration office
Generally the cheaper option, and can be done any time before your trip, without the time pressure of an imminent flight. This is the more relaxed route if your travel dates are already known in advance.
At the airport, on the day of departure
Most major international airports (Suvarnabhumi, Don Mueang, Phuket, Chiang Mai) have a dedicated re-entry permit counter in the departures area, before passport control. This is more convenient if you didn’t plan ahead, but typically costs somewhat more than the immigration office rate, and requires extra time built into your airport arrival — commonly recommended at an extra 1–3 hours beyond your normal check-in buffer.
7. Step-by-step: applying at an immigration office
- Complete form TM.8 (Application for Re-Entry Permit into the Kingdom), available at the office or downloadable in advance
- Bring your original passport, plus photocopies of the biodata page and your current visa/extension stamp
- Bring a recent passport-style photo
- Pay the fee (cash, typically)
- Receive the permit as a stamp or sticker directly in your passport, usually processed the same visit
8. Step-by-step: applying at the airport
- Arrive well ahead of your normal check-in time — at least 1–3 hours earlier than you otherwise would
- Locate the Immigration/re-entry permit counter in the departures area, before the main passport control queue
- Complete TM.8 on the spot (or have it pre-filled if you downloaded it in advance)
- Present your passport, copies, and photo (some counters can take the photo on-site)
- Pay the (typically higher) airport-counter fee
- Receive your stamped permit, then proceed to check-in and outbound immigration as normal
9. Documents you’ll need
- Original passport, valid for at least 6 months, with your current visa/extension stamp clearly visible
- Photocopies of your passport biodata page and current visa/extension page
- A recent passport-style photo
- Completed TM.8 form
- The correct fee, in cash
10. Costs, in full
| Where | Single re-entry | Multiple re-entry |
|---|---|---|
| Immigration office | ~1,000 THB | ~3,800 THB |
| Airport counter | ~1,200 THB | ~4,000 THB |
Fees are widely cited at these levels but can change, and airport service surcharges have trended upward in recent years — verify the current amount with Thai Immigration or at the counter before you rely on a specific figure.
11. What a re-entry permit does NOT do
- It doesn’t extend your permission to stay — your original “admitted until” date remains exactly the same
- It doesn’t replace or substitute for your visa or extension — you still need a valid underlying status for it to attach to
- It doesn’t cover 90-day reporting or TM30 obligations, which continue independently
- It doesn’t guarantee re-entry on its own — immigration officers still assess your return under standard entry conditions
12. What happens if you leave without one
Practically, this means: you can’t simply “pick up where you left off” on return. In most cases, you’d need to apply for an entirely new visa or entry status from outside Thailand and start the qualifying process again — for a retirement or marriage extension, that can mean re-establishing the financial and documentary requirements from scratch, not just re-entering with your old paperwork.
13. Re-entry permits for family members
Each person travelling on their own passport and visa needs their own individual re-entry permit — this includes spouses and children holding dependent visas. There’s no single household or family permit that covers multiple passports under one application; each family member’s documents and fee are handled separately.
14. Timing: when to apply
- Well before travel, at an immigration office — the calmer, cheaper option if your trip is planned in advance
- On the day, at the airport — workable for last-minute trips, but budget significantly more time and expect a higher fee
- Never after you’ve already left — there’s no way to retroactively apply for a re-entry permit once you’ve exited the country; it has to be arranged before departure
15. Common mistakes
- Assuming a “multiple-entry visa” on paper still applies after it’s been converted into an in-country extension. Check which status you actually hold before travelling.
- Leaving on a short, spontaneous trip and forgetting the permit entirely — the rule applies just as strictly to a weekend trip as to a month-long one.
- Arriving at the airport without enough buffer time, then rushing the process or missing the flight.
- Applying for a single permit when multiple trips are planned, paying more in total than a multiple permit would have cost.
- Assuming the permit extends your stay, rather than simply preserving your existing expiry date.
- Not arranging separate permits for each family member, assuming one application covers the household.
16. Frequently asked questions
Do I need a re-entry permit if my visa says “multiple entry”?
Generally not while that visa is still being used in its original form, but once it’s been converted into an in-country extension of stay, the extension itself typically needs its own re-entry permit. Check your specific status before travelling.
How much does a re-entry permit cost?
Roughly 1,000 THB for a single permit and 3,800 THB for a multiple permit at an immigration office, with somewhat higher fees at airport counters. Always confirm the current figure, as fees can change.
Can I apply for a re-entry permit online?
As of 2026, no — applications are made in person, either at a Thai immigration office or at an airport counter on the day of departure.
What happens if I forget and leave without one?
Your current extension of stay is cancelled the moment you exit Thailand. You would generally need to apply for a new visa from outside the country and restart the qualifying process to return under a similar status.
Does a re-entry permit extend my visa?
No. It preserves your existing “admitted until” date; it doesn’t add any extra time. If your extension is due to expire soon, you still need to handle that renewal separately.
Is it cheaper at the immigration office or the airport?
The immigration office is typically cheaper. The airport counter costs somewhat more but is more convenient for last-minute travel.
How many trips does a multiple re-entry permit cover?
Unlimited departures and returns for the remaining validity period of your current extension of stay — not a fixed number of trips.
Do my children need their own re-entry permit?
Yes. Every individual travelling on their own passport and visa, including dependent children, needs a separate re-entry permit.
Can I get a re-entry permit after I’ve already left Thailand?
No. It must be arranged before you depart. Once you’ve exited without one, the protection it would have offered no longer applies.
How early should I arrive at the airport if applying there?
Commonly recommended at least 1–3 hours earlier than your normal check-in time, to allow for the additional application and payment process before your flight.
Does the DTV visa need a separate re-entry permit?
Generally not, since the DTV is issued as a multiple-entry visa in its own right — but always confirm against your specific stamp and current rules, since visa categories and their treatment can be updated.
Is a re-entry permit the same as a visa?
No. It’s a supplementary stamp that protects an existing visa or extension of stay; it isn’t a visa in its own right and can’t be used on its own to enter Thailand.
17. Practical tips
- If you know you’re staying long-term and travelling more than once, get the multiple re-entry permit early rather than paying for single permits trip by trip.
- Apply at an immigration office in advance whenever your travel dates are known, rather than defaulting to the airport counter out of habit.
- Double-check your visa category before any trip — a genuine multiple-entry visa and an in-country extension of stay are treated very differently, and confusing the two is the single costliest mistake covered in this guide.
- Keep spare passport photocopies and photos on hand so a missing document never turns into a delay at a busy counter.
- Build this into your pre-travel checklist permanently, alongside your 90-day report and TM30 status, so it becomes routine rather than something you have to remember to think about each time.
