    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.

Chiang Mai sits in Thailand's mountainous north. Arriving here tends to be straightforward for most travelers. The paperwork deserves attention before you book your flight. Thailand requires all non-Thai nationals to file a free digital arrival card ahead of entry. Depending on your nationality, you may also need a visa or qualify for visa-free entry. Getting these formalities right before departure saves considerable hassle at immigration. Chiang Mai International Airport handles the bulk of arrivals. Some travelers reach the city overland from Bangkok or from neighboring countries. Regardless of how you arrive in Chiang Mai, the immigration process is the same. You will need a valid passport, your completed digital arrival card, and supporting documents. Requirements do shift. Checking the official Thai immigration website before finalizing travel plans is worth the few minutes it takes. One practical note for Chiang Mai specifically: the airport is compact and immigration queues tend to move at a reasonable pace compared to Bangkok's Suvarnabhumi. Peak season from November through February can slow things down. Having your documents organized and accessible makes a noticeable difference.

Visa Requirements

Entry permissions vary by nationality. Find your category below.

Thailand's visa policy depends on your nationality, the purpose of your visit, and how long you intend to stay. The country maintains a visa-exemption arrangement with several dozen nations for short tourism visits. An electronic visa system exists for those who need pre-approval. Traditional visa applications run through Thai embassies and consulates abroad. The rules below apply to Chiang Mai and all other Thai entry points equally.

Visa-Free Entry
Up to 30 days per entry, extendable by up to 30 additional days in-country

Holders of ordinary passports from the countries and territories on Thailand's visa-exemption list may enter for tourism without obtaining a visa beforehand. Since September 2026, eligible travelers may stay up to 30 days per visit. A maximum of two visa-exempt entries is permitted per calendar year. On arrival, immigration officers will ask for proof of accommodation and proof of onward travel within the allowed stay period. They may request evidence of sufficient funds. An extension of up to 30 days can be requested at an immigration office inside Thailand. Travelers planning more than two visits in a year should apply for a visa instead. The same applies to those visiting for purposes other than tourism.

Eligibility and permitted stay depend on your nationality. Thailand's visa-exemption list currently covers 60 countries and territories. Check the official Thai immigration website to confirm whether your passport qualifies. The list is subject to change.

Electronic Travel Authorization (ETA/eVisa)
Varies by visa type and nationality

Travelers who need a visa for Thailand can apply through the official Thailand Electronic Visa website before travel. The e-Visa covers tourist visas, non-immigrant visas, and other categories depending on your purpose of visit. The e-Visa is entirely separate from the Thailand Digital Arrival Card. Every non-Thai arrival must still file the TDAC regardless of visa status.

How to Apply: Applications are submitted through the official Thailand e-Visa portal. You will typically need a passport-sized photo, a copy of your passport's biographical page, proof of accommodation, proof of onward travel, and evidence of sufficient funds. Processing times vary. Apply well in advance of your intended travel date.
Cost: Fees vary depending on visa type. Check the official Thailand e-Visa portal for current fee schedules.

The e-Visa does not replace the Thailand Digital Arrival Card. Even with an approved e-Visa, you must still complete the TDAC within three days before your arrival date.

Visa Required
Varies by visa type

Nationals not covered by the visa-exemption list will need to apply for a visa through a Thai embassy or consulate before traveling. This typically applies to longer stays, work permits, study visas, and certain nationalities for tourism visits as well.

How to Apply: Contact the nearest Thai embassy or consulate for application requirements. These generally include a completed application form, passport photos, proof of financial means, and documentation supporting the purpose of your visit. Some applicants may be asked to attend an interview. Allow several weeks for processing.

Requirements and processing times differ between embassies. For the most current information, check Thailand's official immigration website. Alternatively, contact your nearest Thai diplomatic mission directly.

Arrival Process

Whether you arrive at Chiang Mai International Airport on a direct flight, connect through Bangkok, or cross overland, the entry process follows the same steps. Having your paperwork ready and organized makes things considerably smoother. Chiang Mai's compact airport works in your favor here.

1
Complete the Thailand Digital Arrival Card before you travel
All non-Thai nationals entering Thailand by air, land, or sea must file a Thailand Digital Arrival Card. This includes infants and children. It applies whether you are visa-exempt, hold a visa on arrival, or have a pre-approved visa. You can complete it through the official TDAC portal or through THIM, the Thai Immigration Bureau's official app, available on both major app stores. The card must be filed within three days before your arrival date, including the arrival date itself. You need a new one for every entry into Thailand. The TDAC is free. Be cautious of look-alike websites that charge a fee for this free service. If you have not completed it before arriving in Chiang Mai, kiosks and Wi-Fi are available at the airport. Doing it in advance saves time. Crew members and transit passengers who do not pass through immigration are exempt.
2
Obtain your visa if required
If your nationality requires a visa, apply through the official Thailand e-Visa website before traveling. The e-Visa is entirely separate from the Digital Arrival Card. Having one does not exempt you from filing the TDAC. Visa-exempt travelers can skip this step. Confirm your exemption status on the official immigration website before departure.
3
Proceed through immigration at Chiang Mai
At Chiang Mai International Airport, follow signs to the immigration hall after disembarking. Have your passport, TDAC confirmation, and any visa documentation ready. Immigration officers may ask to see proof of accommodation, proof of onward travel within your permitted stay, and evidence of sufficient funds. For visa-exempt entries, the officer will stamp your passport with the permitted duration of stay. The process at Chiang Mai is typically efficient, though queues can stretch during the high season months.
4
Collect baggage and clear customs
After passing through immigration, proceed to the baggage carousel. Once you have your luggage, pass through the customs checkpoint. If you have nothing to declare, use the green channel. If you are carrying items above the duty-free allowances, restricted goods, or amounts of currency above the declaration threshold, use the red channel and declare them to a customs officer.

Documents to Have Ready

Valid passport
Your passport should typically be valid for at least six months beyond your intended stay in Thailand. Airlines may refuse boarding if your passport falls short of this requirement, and immigration may deny entry.
Thailand Digital Arrival Card (TDAC)
Mandatory for all non-Thai nationals entering Thailand, including infants and children, regardless of visa status. Filed for free through the official TDAC portal or the THIM app within three days before arrival, including the arrival date. A new card is required for each entry.
Visa or e-Visa confirmation
Required if your nationality is not on the visa-exemption list. Apply through the official Thailand e-Visa website before travel. Visa-exempt travelers do not need this but should be prepared to demonstrate their eligibility if asked.
Proof of accommodation
Immigration officers routinely ask for this. A hotel booking confirmation, a guesthouse reservation in Chiang Mai, or a letter from your host will suffice.
Proof of onward travel
A return flight ticket or confirmed booking for onward travel departing Thailand within your permitted stay period. This is checked at immigration and sometimes verified by airline staff at check-in.
Proof of sufficient funds
Immigration officers may ask for evidence that you can support yourself during your stay in Chiang Mai and Thailand. Carrying a recent bank statement or having one accessible on your phone is a reasonable precaution.

Tips for Smooth Entry

Complete your Thailand Digital Arrival Card before reaching Chiang Mai. While kiosks are available at the airport, filling it in at your hotel or before departure means one fewer queue to deal with on arrival.
Keep a printed or easily accessible digital copy of your accommodation booking, return flight, and TDAC confirmation. Immigration officers at Chiang Mai airport do ask to see these, and having them ready speeds things along.
If you are arriving during Chiang Mai's high season, roughly November through February, expect slightly longer immigration queues. Arriving on a weekday or on an earlier flight tends to mean shorter waits.
Be cautious of unofficial websites offering to file your TDAC for a fee. The official portal and the THIM app are both free. If a site asks for payment, it is not the official service.
For visa-exempt entries, keep the two-visit-per-calendar-year limit in mind. If you are planning several trips to Thailand in the same year, you may need to apply for a proper visa for visits beyond the second.

Customs & Duty-Free

Thailand's customs regulations at Chiang Mai are consistent with the rest of the country. Most personal belongings and reasonable quantities of goods for personal use pass through without issue. But there are specific allowances and restrictions worth knowing before you pack.

Alcohol
A limited quantity of alcoholic beverages for personal consumption
Travelers must be of legal drinking age. Exceeding the allowance may result in confiscation and a duty charge. Thailand enforces these limits, and customs officers do check.
Tobacco
A limited quantity of cigarettes or tobacco products for personal use
Thailand enforces tobacco import limits strictly. As it happens, electronic cigarettes, vaping devices, and their refill liquids are illegal to import and possess in Thailand, and this is enforced with potential fines and confiscation. This catches some travelers off guard.
Currency
Amounts of Thai or foreign currency above the declaration threshold must be declared to customs
There is no prohibition on bringing currency into Thailand. But large amounts require a customs declaration. Check the current threshold on the Thai customs department's website before traveling.
Gifts/Goods
Personal effects and gifts within a reasonable value for personal use
Goods that appear intended for commercial resale may be subject to import duties. Keeping receipts for higher-value items you are bringing into and out of the country is a reasonable precaution.

Prohibited Items

  • Narcotics and psychotropic substances, which Thailand treats as a serious criminal offense carrying severe penalties
  • Electronic cigarettes, vaping devices, and their refill liquids, which are illegal to import and possess in Thailand
  • Pornographic materials in any format
  • Counterfeit goods, including clothing, accessories, and media bearing trademarked brands
  • Certain weapons, including firearms without proper permits

Restricted Items

  • Prescription medications require a doctor's letter and original packaging. Some medications that are legal elsewhere are controlled substances in Thailand, so verify your specific medications before packing
  • Buddha images, artifacts, and antiques require an export license from the Fine Arts Department if you plan to take them out of Thailand when you leave
  • Certain food products, plant materials, and animal products may require phytosanitary or health certificates
  • Drones require registration with Thailand's telecommunications regulator before use in the country

Health Requirements

Thailand does not impose extensive health documentation requirements for most travelers arriving in Chiang Mai. But there are a few important points to be aware of before you travel.

Required Vaccinations

  • You need a yellow fever vaccination certificate if you arrive from, or recently passed through, any country with yellow fever transmission risk. Thailand can refuse entry without this certificate in those cases.

Recommended Vaccinations

  • Get Hepatitis A. Foodborne transmission happens. Street food in Chiang Mai makes this shot relevant.
  • Hepatitis B matters for longer stays. Medical procedures raise the risk.
  • Typhoid, another food and waterborne consideration for northern Thailand
  • Japanese Encephalitis. Consider it for extended rural stays around Chiang Mai.
  • Rabies. Temple monkeys and countryside dogs make this shot sensible for Chiang Mai visitors.
  • Update routine vaccinations. Tetanus, diphtheria, and measles. Do this before departure.

Health Insurance

Thailand does not require health insurance proof for short-stay tourists. Get coverage anyway. Medical care in Chiang Mai is generally good. Several hospitals treat international patients regularly. Serious illness gets expensive fast. Buy travel insurance with medical evacuation coverage. Some conditions require Bangkok transfer.

Current Health Requirements: The yellow fever certificate is the only health document you might show at arrival. Only applies if you come from a country with yellow fever. No health documents required from other regions. Check Thailand's official public health authority before traveling. Requirements shift with regional health developments.

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.
