Mae Sai Entry Requirements
Visa, immigration, and customs information
-
Thailand Digital Arrival Card (TDAC)
- Who
- All non-Thai nationals entering Thailand by air, land or sea, including infants and children and visa-exempt or visa-on-arrival travellers

- Within 3 days before arrival (including the arrival date); a new card for every entry
- Cost
- Free
The TDAC is filed online or in THIM, the Thai Immigration Bureau's official app, and is not a visa. Crew, and transit passengers who do not pass through immigration, do not need one. Kiosks and Wi-Fi are available on arrival. Look-alike websites charge for this free card.

Thailand visa exemption for tourism (up to 30 days)
- Who
- Ordinary passport holders of the 60 countries and territories on Thailand's visa-exemption list, visiting for tourism
- When
- At entry, at most twice per calendar year
Since 15 September 2026 eligible visitors may stay up to 30 days without a visa. On arrival, immigration officers ask for proof of accommodation and of onward travel within 30 days, and may ask for proof of funds of 20,000 THB per person. An extension of up to 30 days can be requested in Thailand. Travellers planning more than two visits a year, or a purpose other than tourism, should apply for a visa.

Visa Requirements
Entry permissions vary by nationality. Find your category below.
Thailand applies one visa policy everywhere, Mae Sai included. Your visa needs and permitted stay depend solely on nationality and passport type.
Some ordinary passport holders enter Thailand for tourism without advance visas.
This covers tourism only. Officers may want onward travel proof and adequate funds. Land borders like Mae Sai allow this exemption twice yearly. Longer or frequent visits need visas.
Thailand runs an e-Visa system for travellers requiring visas. Apply online before departure.
Cost: Visa fees vary by nationality and type. Check the official website.
The e-Visa differs from the Digital Arrival Card. You need both. Apply early for Mae Sai trips.
Nationalities ineligible for exemptions or e-Visas must seek traditional visas through Thai embassies or consulates.
Processing times and documents vary widely. Start weeks or months before visiting Mae Sai.
Arrival Process
Mae Sai land border entry runs efficiently. Approach the Thai immigration building, queue up, and present documents to an officer.
Documents to Have Ready
Tips for Smooth Entry
Customs & Duty-Free
Post-immigration, you pass through Mae Sai customs. Declarations are verbal or via forms for restricted items.
Prohibited Items
- Narcotic drugs - illegal under Thai law with severe penalties
- Obscene materials - including certain publications and digital media
- Counterfeit goods and copyright-infringing items
- Firearms and ammunition without a permit
- Fresh fruits, vegetables, and plants without phytosanitary certificates
Restricted Items
- Prescription medications need original containers with doctor's prescriptions, for psychotropic substances
- Pets - require an import permit and health certificates from country of origin
- Gold - amounts over a certain weight require a declaration
Health Requirements
Mae Sai follows Thailand's standard health entry rules. No extra paperwork needed. Same vaccines as Bangkok or Phuket. General advice applies.
Recommended Vaccinations
- Get these basics sorted: MMR, diphtheria-tetanus-pertussis, varicella, polio, and influenza.
- Hepatitis A
- Typhoid
- Japanese encephalitis matters for rural stays. Think rice paddies and monsoon season. Worth it if you're staying long.
- Rabies (for those with outdoor/animal exposure risk)
Health Insurance
Travel insurance is strongly recommended. Check the current entry rules on the official government website before you travel. Get it anyway. Thai hospitals are solid. Foreigners pay full price without coverage. Bills add up fast.
Protect Your Trip with Travel Insurance
Comprehensive coverage for medical emergencies, trip cancellation, lost luggage, and 24/7 emergency assistance. Many countries recommend or require travel insurance.

Special Situations
Additional requirements for specific circumstances.
Kids need their own passport. Full stop. Traveling with one parent or alone? Bring a notarized consent letter from whoever's absent. Immigration might not ask. If they do, you'll wait hours without it. Pack the letter.
Bringing pets through Mae Sai takes planning. You'll need an import permit from the Thai Department of Livestock Development, plus rabies proof and an international health certificate from your home vet. Start weeks out. The process drags.
Overstaying? Visit Thai immigration in Chiang Rai, the nearest office to Mae Sai. Tourist extensions run up to 30 days. Not guaranteed. Bring cash for the fee. Apply early.
