Mae Sai Entry Requirements

Visa, immigration, and customs information

Mae Sai is Thailand's northernmost border town, connected to Tachileik, Myanmar by the Mae Sai-Tachileik Friendship Bridge. Entering Mae Sai from within Thailand (e.g., by flight to Chiang Rai and then road transport) follows standard Thai immigration rules for international arrivals to the country. Travelers must pass through immigration control, which involves presenting a valid passport, completed arrival/departure card (TM.6), and any required visa. The process is generally straightforward, but wait times can vary, during peak tourist seasons or holidays. For travelers crossing the land border from Myanmar into Mae Sai, entry is subject to standard Thai visa regulations. visa-on-arrival and visa-exempt entries at land borders have more restrictive rules compared to air arrivals, including stricter proof of funds and onward travel requirements. Border runs for visa extensions are heavily scrutinized, and frequent consecutive entries may lead to denial by immigration officers. Before traveling, all visitors should ensure their passport has at least six months' validity remaining, has several blank pages, and that they possess the correct visa or meet visa-exempt criteria. Always check the latest entry requirements, as policies, regarding land border crossings, can change with little notice.

Visa Requirements

Entry permissions vary by nationality. Find your category below.

Thailand's visa policy applies to entry at Mae Sai. The type of visa or exemption you need depends primarily on your nationality and point of entry (air vs. land).

Visa-Free Entry (Visa Exemption)

30 days when entering via a land border (e.g., Mae Sai from Myanmar). 30 days when entering via international airport (extendable by 30 days at immigration office). Note: 90-day exemption for some nationalities is only for air arrivals.

Citizens of eligible countries can enter Thailand for tourism without a visa for a limited period.

Includes

United Kingdom United States Canada Australia Germany France Italy Spain Netherlands Sweden Denmark Norway Finland Singapore Hong Kong South Korea Japan Malaysia Vietnam Indonesia Brazil

At land borders like Mae Sai, the visa exemption is strictly 30 days per entry and is limited to two entries per calendar year. You must show proof of onward travel (flight/bus ticket out of Thailand) and sufficient funds (20,000 THB per person or 40,000 THB per family). Immigration may deny entry if they suspect you are working illegally or abusing the system.

Electronic Travel Authorization (ETA/eVisa)

60 days (extendable by 30 days at immigration office).

Thailand does not currently have a general eVisa system for tourist visas. However, citizens of certain countries can apply for a Tourist Visa (TR) online via the official e-Visa website, which replaces the need to apply at an embassy.

Includes

China India Saudi Arabia Ukraine Kazakhstan Taiwan

How to Apply: Apply online via the official Thailand e-Visa website. Processing typically takes 3-15 working days. An approved e-Visa must be printed and presented upon arrival.
Cost: Approximately 1,000 - 2,500 THB (varies by nationality and embassy/consulate).

The e-Visa is a pre-approved visa, not a visa-on-arrival. It must be obtained before travel. It is valid for entry via designated airports and land border checkpoints, which include Mae Sai.

Visa Required

Depends on visa type (e.g., Single-Entry Tourist Visa: 60 days).

Citizens of countries not eligible for visa exemption or e-Visa must apply for a visa at a Thai embassy or consulate before travel.

How to Apply: Apply in person or by mail at a Royal Thai Embassy or Consulate in your country of residence. Requires application form, photos, passport, fee, and supporting documents like flight itineraries and bank statements.

Some nationalities are also eligible for a Visa on Arrival (VOA) at certain international airports and land borders, but NOT at the Mae Sai land border. VOA is for a 15-day stay and requires specific documents (passport photo, fee, proof of funds, onward ticket). Check the official immigration website to see if your nationality qualifies for VOA and where it is available.

Arrival Process

The entry process at the Mae Sai land border involves crossing the bridge from Tachileik, Myanmar, and proceeding through Thai immigration. The process is similar at airports but with more formal queues and procedures.

1. Approach Immigration Counter

Join the appropriate queue ('Foreign Passport'). Have your passport, completed TM.6 arrival/departure card, visa (if required), and supporting documents ready.

2. Document Check & Interview

The immigration officer will scan your passport, check your visa or exemption status, stamp your passport, and may ask questions about your visit (purpose, duration, accommodation, funds).

3. Passport Stamping

If admitted, the officer will stamp your passport with an Arrival Stamp, indicating the date of entry and the 'Admitted Until' date. You will receive the departure portion (TM.6) of your card—KEEP THIS SAFELY as you must surrender it when leaving Thailand.

4. Proceed to Customs

After immigration, you may be subject to a customs screening. Have your baggage ready for potential inspection and declare any items if necessary.

Documents to Have Ready

Passport

Must be valid for at least 6 months beyond your date of entry and have at least one blank visa page.

Completed TM.6 Card

The Arrival/Departure card (usually distributed on flights or at the border). Both sections must be filled out.

Valid Thai Visa or Proof of Exemption

Either a visa sticker/stamp in your passport or proof of nationality from a visa-exempt country.

Proof of Onward Travel

A confirmed ticket for departure from Thailand within your permitted stay period (e.g., flight, bus, or train ticket out of the country).

Proof of Sufficient Funds

Cash or equivalent of 20,000 THB per person or 40,000 THB per family. Officers may ask to see it, at land borders.

Tips for Smooth Entry

Fill out the TM.6 card neatly and completely in capital letters before reaching the officer to speed up the process.

Be polite, confident, and answer questions clearly and concisely. Avoid appearing nervous or giving vague answers.

Have all required documents (passport, TM.6, onward ticket, proof of funds) organized and easily accessible in your hand when you reach the counter.

Dress neatly. While there's no formal dress code, looking presentable can create a positive impression with immigration officers.

If entering on a visa exemption at a land border, be prepared to show your exit stamp from Myanmar or proof you legally entered there.

Health Insurance

Not mandatory for tourist visa or visa-exempt entry, but is HIGHLY RECOMMENDED. Medical treatment in Thailand can be expensive for foreigners. Ensure your policy covers medical evacuation (medevac). Some visa types (e.g., long-term retirement, education) require proof of health insurance.

Current Health Requirements: As of October 2024, there are no COVID-19 vaccination, testing, or quarantine requirements for entry into Thailand. This is subject to change; always check the latest updates from the Thai Ministry of Public Health and your airline before travel.

Special Situations

Additional requirements for specific circumstances.

Traveling with Children

Children must have their own passport. If a child is traveling with only one parent or without parents, it is advisable (though not always checked) to carry a notarized letter of consent from the non-accompanying parent(s). This can prevent delays or denial of entry if immigration suspects child abduction.

Traveling with Pets

Dogs and cats require an import permit from the Thai Department of Livestock Development, a valid rabies vaccination certificate (administered 21 days to 1 year before travel), a veterinary health certificate issued within 10 days of travel, and may require a rabies antibody titer test (RNATT) from an approved lab. Pets are subject to quarantine upon arrival if requirements are not met. Advance planning (months) is essential.

Extended Stays

To stay longer than your initial permission (e.g., 30-day exemption or 60-day tourist visa), you can apply for a 30-day extension at your local immigration office (e.g., Chiang Rai Immigration) for a fee of 1,900 THB, subject to approval. Other options include applying for a different visa (e.g., Education, Retirement, Elite) from a Thai embassy abroad. Consecutive 'border runs' for new visa exemptions are heavily discouraged and may lead to entry denial.
