Chiang Mai Entry Requirements
Visa, immigration, and customs information

Thailand Digital Arrival Card (TDAC)

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.

Visa Requirements
Entry permissions vary by nationality. Find your category below.
Thailand's visa policy governs Chiang Mai entry. Your passport determines your requirements. Stay length varies by nationality.
Visa-exempt nationalities enter without advance paperwork. As of late 2026, eligible visitors receive 30 days per entry. Annual limits apply to certain nationalities.
This covers tourism only. Officers may request onward travel proof within 30 days. Bring accommodation confirmation. Carry evidence of adequate funds.
The Thailand e-Visa serves nationalities requiring advance permission. It's electronic. Apply online before departure.
Cost: Fees vary by visa type and nationality.
The e-Visa differs from the Digital Arrival Card. All foreign travelers need both. Use only official government websites.
Some nationalities need embassy visas. These travelers cannot use visa exemption or e-Visa options.
Processing times and document requirements differ by embassy. Contact your specific mission directly. Verify their current procedures.
Arrival Process
Chiang Mai International Airport keeps immigration simple. Procedures match other Thai international airports.
Documents to Have Ready
Tips for Smooth Entry
Customs & Duty-Free
Thai customs rules apply in Chiang Mai. Know your limits. Avoid fines and confiscation.
Prohibited Items
- Narcotics and illegal drugs - strict laws with severe penalties
- Obscene material or pornography
- Counterfeit goods and pirated copyright items
- Firearms and ammunition without a permit
- Certain fresh fruits, plants, and soil to prevent pest introduction
Restricted Items
- Keep prescription medications in original containers. Carry doctor's prescriptions. Essential for controlled substances.
- Electronic cigarettes and vaping devices - these are prohibited in Thailand
- Wildlife and wildlife products - require CITES permits to prevent illegal trade
Health Requirements
No health documents currently required for Chiang Mai entry. Take sensible precautions anyway. Plan ahead.
Recommended Vaccinations
- Routine vaccinations (MMR, diphtheria-tetanus-pertussis, varicella, polio, flu)
- Hepatitis An and Typhoid (due to food and water risks)
- Hepatitis B (for potential medical treatment or intimate contact)
- Rabies (for those planning extensive outdoor activities or animal interactions)
- Consider Japanese Encephalitis vaccination for extended rural stays during transmission season.
Health Insurance
Travel insurance is strongly recommended. Check the current entry rules on the official government website before you travel. Get it anyway. Foreign medical treatment in Thailand costs heavily. Insurance covers illness, accidents, and evacuation.
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.
Children, including infants, require their own passport and Thailand Digital Arrival Card. If a child is traveling with only one parent or without parents, immigration may ask for a letter of consent from the absent parent(s). It is not a universal rule. Having one prevents questions.
Importing pets like dogs and cats into Thailand involves an import permit from the Department of Livestock Development, a valid rabies vaccination certificate, and a health certificate issued shortly before travel. The rules are detailed and can change. Contact Thai authorities early.
If you wish to stay longer than your initial visa or visa exemption allows, you can apply for an extension at the Chiang Mai Immigration Office. For a standard 30-day tourist exemption, a 30-day extension is often possible for a fee, provided you meet the requirements. Overstaying incurs daily fines. Future entry gets complicated.
Know What to Pack
