Thai citizens planning to visit South Korea for short-term stays now benefit from the convenient Korea Electronic Travel Authorization (K-ETA) system. This online travel permit streamlines the process for eligible visitors by removing the need to visit an embassy or apply for a traditional visa. Whether you're traveling for tourism, business meetings, or cultural events, this guide covers everything Thai citizens need to know about applying for and using a K-ETA

What is the K-ETA for and What Activities Does it Cover?

The Korea Electronic Travel Authorization (K-ETA) is an online entry approval system required for visa-free travelers entering South Korea. It allows eligible nationals, including those from Thailand, to enter South Korea without applying for a visa, as long as the visit is short-term and for permitted purposes that includes:

For any purpose other than those listed above (e.g., long-term study, employment, or residency), Thai citizens must apply for a specific visa through an embassy or consulate in Thailand before traveling.

Can Thai Citizens Apply for the K-ETA?

Yes, Thai passport holders are eligible to apply for a K-ETA when visiting South Korea for short-term stays (up to 90 days). Thai citizens must apply online for K-ETA before boarding their flight to Korea.

K-ETA Validity and Duration of Stay for Thai Citizens

The Korea Electronic Travel Authorization (K-ETA) is valid for three years from the date it is approved, allowing travelers to enter South Korea multiple times during this period without needing to reapply. However, each individual stay must not exceed 90 days. It's important to note that the same passport used for the K-ETA application must be used for travel, as the authorization is linked to that specific document.

Requirements for Thai Citizens to Apply for K-ETA

To successfully apply for a K-ETA, Thai citizens will need the following:

1. Valid Thai Passport: Your passport must be valid for at least six months beyond your intended date of departure from South Korea. The biographical data page of your passport (the page with your photo and personal details) will need to be clearly scanned and uploaded.
2. Valid Email Address: An active and accessible email address is essential, as this is where K-ETA application updates and the final approval notification will be sent.
3. Recent Digital Photo: A clear, high-resolution, recent (taken within the last six months) digital passport-style photo that strictly adheres to K-ETA photo guidelines. 
4. Credit or Debit Card: A valid international credit or debit card is required to pay the non-refundable application fee.

Step 2: Upload a Photo and Pay the Fee

It’s important to note that the K-ETA fee is non-refundable, regardless of whether the application is approved or rejected.

K-ETA Processing Time for Citizens of Thailand

For Thai citizens applying for a K-ETA to visit South Korea, the standard processing time is usually within 1-6 Working Days, though many receive approval much sooner—sometimes within minutes or a few hours.
