Udon Thani Entry Requirements

Visa, immigration, and customs information

Udon Thani, a major city in Thailand's Isaan region, welcomes international travelers through its Udon Thani International Airport (UTH). Entry requirements for Udon Thani are the same as for all of Thailand, governed by Thai immigration law. Most visitors will need a valid passport and, depending on their nationality, either a visa, a visa exemption, or an electronic travel authorization. The immigration process at Udon Thani Airport is generally straightforward and efficient, involving passport control, a potential health screening, and customs clearance. Travelers should ensure their passport has at least six months of validity remaining from the date of entry and have proof of onward travel (such as a return ticket) and sufficient funds for their stay, as these may be requested by immigration officers. Before traveling, it's important to check the latest entry requirements, as visa policies and health regulations can change. While Udon Thani is a popular destination for both tourism and business, travelers should be aware that overstaying a visa or violating the terms of entry can result in fines, detention, or deportation. Planning ahead and having all necessary documents organized will ensure a smooth arrival experience at this gateway to northeastern Thailand.

Visa Requirements

Entry permissions vary by nationality. Find your category below.

Thailand's visa policy applies uniformly across the country, including entry at Udon Thani International Airport. The requirements are primarily based on the traveler's nationality and the purpose and duration of the visit.

Visa-Free Entry

Typically 30 days for most nationalities; 90 days for some (e.g., Argentina, Brazil, Chile, Peru, South Korea).

Citizens of eligible countries can enter Thailand for tourism purposes without obtaining a visa in advance.

Includes

United Kingdom United States Canada Australia New Zealand Germany France Italy Spain Japan Singapore Malaysia Vietnam Indonesia Laos Cambodia Myanmar

Entry is granted for tourism only. Passport must be valid for at least 6 months. Proof of onward travel and adequate funds (20,000 THB per person, 40,000 THB per family) may be requested. The 30/90-day stay is not extendable. Travelers must enter through an international airport; land border entries from neighboring countries grant only 15 days visa-free.

Electronic Travel Authorization (ETA/eVisa)

15 days for VoA; 60 days for a Tourist eVisa (extendable).

Certain nationalities must obtain an eVisa or a visa on arrival (VoA) online prior to travel. Note: Thailand does not have a general ETA system; its primary electronic system is for Tourist Visas and VoA.

China India Saudi Arabia Ukraine Kazakhstan Taiwan Bulgaria Bhutan Cyprus Ethiopia Fiji Georgia Nauru Papua New Guinea Romania Uzbekistan Vanuatu

How to Apply: Apply online via the official Thai eVisa website (https://www.thaievisa.go.th/). Processing typically takes 3-15 business days. The VoA application is also available online for eligible countries.
Cost: Tourist eVisa: 1,500-2,000 THB (approx. $40-$55 USD). Visa on Arrival: 2,000 THB (approx. $55 USD).

The approved eVisa must be printed and presented upon arrival. The online VoA pre-approval speeds up the process at the airport but still requires payment and final approval at the VoA counter.

Visa Required

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

Nationalities not eligible for visa-free entry or eVisa/VoA must apply for a visa at a Royal Thai Embassy or Consulate before travel.

How to Apply: Apply in person or by post at the nearest Royal Thai Embassy or Consulate. Requires application form, passport photos, flight itinerary, proof of accommodation, financial evidence, and fee payment.

Arrival Process

Upon arrival at Udon Thani International Airport (UTH), follow signs for Arrivals and Immigration. The process is typically quick, but lines can form during peak travel times.

1. Health Screening (if applicable)

2. Immigration Passport Control

Proceed to the immigration counters. Present your passport, completed TM6 Arrival/Departure Card (if still in use; often discontinued), and any required visa (printout for eVisa). The officer will stamp your passport with an entry permit indicating your permitted stay date.

3. Baggage Claim

After clearing immigration, collect your checked luggage from the carousels.
