South Korea Visa Thailand

For Thai citizens planning to visit South Korea, the visa policy in 2026 includes several key changes. While Thai passport holders still enjoy 90-day visa-free entry, there is now an additional mandatory step in the entry process: K-ETA (Korea Electronic Travel Authorization) .

This is not a traditional visa application but an electronic authorization procedure designed to streamline entry and enhance border security. Whether you are planning a shopping trip to Seoul, a vacation to Jeju Island, or a short-term business trip, understanding the latest K-ETA requirements is the first step to a smooth journey.

1. Core Entry Policy for Thai Citizens

As of April 2026, the core entry requirements for Thai citizens visiting South Korea are as follows:

CategorySpecific Requirement
Visa StatusVisa-free (K-ETA required)
Maximum Stay90 days (for tourism, transit, short-term business)
Passport ValidityMust be valid for the duration of stay in Korea; at least 6 months remaining is strongly recommended
Application TimingK-ETA application must be completed at least 72 hours before boarding
K-ETA Validity2 years (from the date of approval)
FeeUSD 10 (approximately 350-370 THB)

In short, while Thai citizens do not need to apply for a physical visa sticker from an embassy, they must obtain K-ETA approval online before departure; otherwise, they may be denied boarding.

2. What is K-ETA?

K-ETA is an electronic travel authorization system introduced by South Korea for travelers from visa-waiver countries/regions. Similar to the US ESTA or Canada eTA, its purpose is to conduct a risk assessment of travelers before they board their flight.

Is K-ETA required for Thai citizens?
Yes, Thailand is among the countries requiring K-ETA. However, there is an important exception: if you are a national of one of 22 specific countries/regions (such as the US, Japan, the UK, or Singapore), K-ETA is temporarily waived until the end of 2026. As a Thai citizen, you are required to apply for K-ETA, but the process is entirely online with no need to visit a consulate.

3. K-ETA Online Application Process (Step-by-Step)

The application process is entirely online. You do not need to submit your original passport or attend an interview. Plan ahead to avoid disrupting your travel schedule.

  1. Visit the Official Portal: Access the official K-ETA website or download the official mobile app. Be cautious of fraudulent third-party websites.

  2. Complete the Application: You will need a valid Thai passport, an email address, and a credit/debit card to pay the fee. Information required includes personal details, passport information, and travel plans (such as an address in Korea).

  3. Upload Passport Photo: The system requires an electronic scan of your passport information page (usually in JPG format). Ensure the scan is clear and free of glare.

  4. Pay the Fee: The fee is approximately 10,000 KRW (about USD 10 or 360 THB). Payment is typically made by international credit card or PayPal.

  5. Check Your Approval Email: Most applications are approved within minutes to 24 hours after submission. The approval result will be sent by email. It is recommended to print a physical copy to carry with you, just in case.

⚠️ Important Timing: The application must be completed at least 72 hours before boarding. While many applications are approved instantly, it is recommended to apply at least one week in advance to account for potential system delays or the need to correct information.

4. Required Documents and Entry Guide

Even with a valid K-ETA, immigration officers at your port of arrival may still request to see the following documents. Having these materials ready can significantly speed up your entry.

  1. Valid Thai Passport: Ensure your passport is valid for at least 3 months beyond your intended departure date from Korea. Although the official requirement is 3 months, airlines often require 6 months; it is wise to have ample remaining validity.

  2. K-ETA Approval Confirmation: An electronic or printed copy is acceptable, but a physical printout is recommended in case of electronic device failure.

  3. Round-trip or Onward Ticket: Proof that you will leave Korea within 90 days.

  4. Accommodation Booking Confirmation: Hotel reservation or the address of your host.

  5. Proof of Financial Means: Although rarely checked, it is advisable to carry a credit card or some cash (recommended approximately USD 50-100 per person per day) to demonstrate sufficient funds for your trip.

Customs and Quarantine:

  • Animal and Plant Quarantine: South Korea strictly controls the import of meat products. Do not bring items such as ham, sausages, or other meat products, as you may face heavy fines.

  • Arrival Card: Travelers with a valid K-ETA are generally exempt from filling out the paper Arrival Card. However, if you go through a manned immigration counter, the officer may still request that you complete one.

5. Long-Term Stay and Work Visas: Good News for Thai Job Seekers

If your plan extends beyond short-term tourism, South Korea has significantly relaxed its work visa policies for Thai citizens in 2026, particularly for young professionals.

  • D-10-1 Job Seeker Visa: For Thai citizens under 29 years old who have graduated in Korean language or Korean studies. The new rules have removed financial proof requirements and the points system, while extending the permitted stay from 1 year to 3 years.

  • E-7 Specific Activity Visa: If you have a TOPIK (Test of Proficiency in Korean) certificate, you may be exempt from work experience or academic degree requirements. Science and engineering graduates (from Thai universities ranked in the top 1000 by QS) receive additional points.

For Thai citizens seeking to work in Korea rather than simply travel, these policy changes are a very positive signal. It is recommended to seize the opportunity and plan your Korean language studies in advance.

6. Special Reminders

  • K-ETA is not a visa: If for certain reasons (such as a previous deportation from Korea or a criminal record) you do not qualify for K-ETA approval, you will still need to apply for a traditional visa sticker from the South Korean embassy in Thailand.

  • Consequences of Overstay: The permitted stay with K-ETA is 90 days. Overstaying will result in fines; serious cases may lead to deportation and affect future entry.

  • Policy Validity: International travel policies can change rapidly. Although this information is based on data from April 2026, it is recommended to check the official K-ETA website or the website of the South Korean embassy in Thailand for the latest updates before booking your tickets.

Conclusion

In 2026, traveling to South Korea has become more "digitalized" and "convenient" for Thai citizens. By taking just a few minutes to complete the K-ETA application three days before departure, and preparing the relevant travel documents, you can enjoy 90 days of visa-free travel in Korea, experiencing its food, culture, and shopping. For Thai young people seeking career development, the new work visa policies also offer more practical opportunities beyond the "Korean Wave."

Land Measurement in Thailand

  In Thailand, land is not merely an asset; it is a meticulously categorized legal entity defined by a measurement system that predates the modern metric era. While the world has largely moved toward square meters and hectares, the Thai real estate market—and its legal system—operates on a unique hierarchy of Rai , Ngan , and Square Wah . As of 2026, understanding these units is more critical than ever, as the Thai Land Department has accelerated its GIS (Geographic Information System) integration, making digital accuracy the new standard for property transactions. 1. The Thai Measurement Hierarchy The Thai system is highly structured, and conversions are exact. Unlike some historical systems that vary by region, the modern Thai Land Code standardizes these units across the Kingdom. The Core Units 1 Square Wah (Talang Wah): The basic building block, equivalent to 4 square meters . This is roughly the size of a small bathroom or a garden shed. 1 Ngan: Equal to 100 Square Wah ,...

Thailand Digital Arrival Card

I n 2026, Thailand’s entry landscape has undergone its most significant digital transformation in decades. The centerpiece of this evolution is the Thailand Digital Arrival Card (TDAC) , which officially replaced the iconic blue-and-white paper TM6 form on May 1, 2025. For decades, the physical TM6 was a staple of the "Thai experience"—usually scrambled for mid-flight or at a crowded podium in Suvarnabhumi Airport. Today, that process is entirely paperless. The TDAC is not just a digital copy of the old card; it is a sophisticated, integrated platform that links immigration, health, and security data into a single QR code. 1. The Death of the TM6 and the Birth of TDAC The transition from paper to digital was born out of necessity. In 2024, Thailand faced a surge in tourism that frequently led to "immigration bottlenecks." By digitizing the arrival card, the government has moved the data-entry burden from the border officer to the traveler, allowing for a "pre-...

Buying Land in Thailand

For foreign investors and individuals seeking to purchase land in Thailand, the legal landscape presents both significant opportunities and strict limitations. While the fundamental prohibition against foreign land ownership remains firmly in place, 2026 has brought intensified enforcement against illegal structures alongside refined pathways for compliant investment. This comprehensive guide provides an in-depth examination of the legal framework, available options, and critical compliance considerations for anyone considering land acquisition in Thailand . The Fundamental Prohibition: Foreign Land Ownership Under the  Thai Land Code B.E. 2497 (1954)  , foreign individuals and entities are generally prohibited from owning land in Thailand  . This is not a gray area or matter of interpretation—Land Code Section 86 explicitly prohibits alien land ownership, and Sections 111-113 impose criminal penalties for violations  . The prohibition applies broadly. A "foreign ent...
