Thailand entry requirements at a glance
These Thailand entry requirements combine a passport rule, a visa rule and an arrival declaration, and different people check each one along the way. Before you fly, confirm your passport validity, your visa or exemption route, and the free TDAC card, then use the table below to check what each requirement means for your nationality and travel dates.
| Requirement | What it means | What to verify |
|---|---|---|
| Passport validity | The passport should remain valid for at least six months from the planned date of arrival | Compare the expiry date with your arrival date; airlines may check it at check-in |
| Visa or exemption | Your nationality and residence decide whether you enter visa-free or need a tourist eVisa | Check the published exemption lists and confirm your route before booking flights |
| TDAC arrival card | All travellers complete the free Thailand Digital Arrival Card within 72 hours before departure | Submit the card in the correct window and keep the confirmation safe |
| Printed eVisa | eVisa holders typically carry a printed copy of the approved eVisa with the passport used to apply | Print the approved PDF and check the name and passport number match |
| Onward travel and stay | An onward or return ticket and accommodation details may be requested at the border | Keep booking confirmations that match the dates you stated in your application |
Passport and document rules
The passport you travel with is the anchor of every Thailand entry requirement. Published Thai entry rules are generally built around a passport that stays valid for at least six months beyond your planned date of arrival, and the check can happen twice: first by the airline at check-in, then by Thai immigration on arrival.
- Compare the passport expiry date with your arrival date, not your departure date.
- Carry a printed copy of the approved eVisa PDF together with the passport used in the application.
- Make sure the name and passport number on the issued eVisa match your passport exactly.
- Keep an onward or return ticket and accommodation details where you can reach them quickly.
- Travel with a backup: a secure photo or photocopy of the data page, kept separately from the passport.
If your passport was renewed or replaced after your visa was approved, the issued eVisa stays linked to the old document, so confirm what must be updated before you depart; the Thailand eVisa status check page shows how to revisit your application record. Airlines and officers may also ask why you are visiting and where you will stay, and our Thailand tourist eVisa documents checklist lists the paperwork the application service linked from this site typically asks you to prepare.
Do you need a visa for Thailand?
Whether you need a visa depends on your nationality and where you legally reside, so there is no single answer for every traveller. Three published routes cover most tourist trips, and it pays to confirm yours before booking flights.
Visa exemption
Travellers on the published exemption lists can enter visa-free for short stays. The lists in force from 15 September 2026 allow 30-day visa-free stays for many nationalities, with bilateral variants, so check the Thailand visa exemption page for your passport.
Tourist eVisa
If your nationality is not on an exemption list, apply for a tourist eVisa before you travel. It typically allows a stay of up to 60 days and is issued with a validity of three or six months from issue, as set out in the Thailand tourist eVisa guide.
Visa on arrival
A published group of nationalities can still obtain a visa on arrival at the airport. This route typically means queues and a fee, so confirm your eligibility on the Thailand visa on arrival page before relying on it.
Costs to expect
Whatever route you take, treat published fees as reference figures that can change, and keep assistance charges separate from consular fees, as explained on the Thailand tourist eVisa fees page.
TDAC and arrival steps
Every traveller, visa-free or not, must complete the free Thailand Digital Arrival Card, commonly called the TDAC, within 72 hours before departure. It is an arrival declaration and not a visa: it never replaces a visa, and travellers who need one must hold both the visa and the TDAC confirmation before they fly. The Thailand Digital Arrival Card guide walks through the form field by field.
Complete the TDAC
Submit the free card inside the 72-hour window before departure and save the confirmation.
Print the eVisa
eVisa holders should carry a printed copy of the approved document with their passport.
Check in with evidence
Airlines may ask for your onward ticket and accommodation details at the check-in desk.
Answer at immigration
Officers may ask about your purpose, stay length and address; keep answers consistent.
Thailand entry requirement FAQs
Do I need a visa for Thailand?
It depends on your nationality and residence. Travellers on the published visa exemption lists can enter visa-free for short stays, while other nationalities typically apply for a tourist eVisa before travel. A published group can also use visa on arrival, so check your route against the current published lists before booking.
How long must my passport be valid for Thailand?
The baseline entry rule is a passport valid for at least six months from your planned date of arrival. Airlines may check this at check-in, and Thai immigration can verify it on arrival, so confirm the expiry date well before you fly.
What is the Thailand Digital Arrival Card (TDAC)?
The TDAC is a free digital arrival card that all travellers complete within 72 hours before departure. It is an arrival declaration, not a visa, and it does not replace a visa for travellers who need one. Keep the confirmation with your travel documents.
Do I need a printed copy of my Thailand eVisa?
eVisa holders should carry a printed copy of the approved eVisa together with the passport used in the application. The application service linked from this site lists the printed eVisa among its requirements on arrival, and paper copies are typically easier for airline and immigration staff to check.
How long can I stay in Thailand on a tourist eVisa?
The published tourist eVisa allows a stay of up to 60 days, and the visa itself is issued with a validity of three or six months from the date of issue. Extensions inside Thailand may be possible for a published fee, but your permitted stay is confirmed at the border.
Can I still get a visa on arrival in Thailand?
Visa on arrival exists for a published group of nationalities and is arranged at the airport on arrival. It typically means queues and a fee, so travellers who qualify for visa exemption or a tourist eVisa usually prefer to settle the route before departure.
