Do You Need a Visa or K-ETA to Visit South Korea? 2026 Update

Planning a trip to South Korea but unsure whether Thai travelers need a visa or K-ETA before departure? Whether you are visiting Seoul, admiring the autumn foliage, shopping in Hongdae, or experiencing Korea during the winter season, checking the entry requirements in advance will help you prepare for your trip.

For Thai passport holders traveling to South Korea for a short tourist visit, a tourist visa is generally not required in advance, but K-ETA approval is required before departure unless the traveler qualifies for an exemption. However, final admission to South Korea remains subject to the decision of immigration officers.

This article explains the difference between a visa and K-ETA, how to check the applicable entry requirements, and what you should prepare before traveling.

Information updated as of October 27, 2026. Travelers should check the latest official announcements before departure.

 

Do Thai Citizens Need a Visa to Visit South Korea?

Thai ordinary passport holders traveling to South Korea for short-term tourism generally do not need to apply for a tourist visa in advance, provided they qualify under the applicable visa-exemption arrangements. However, they must comply with K-ETA requirements unless they qualify for an exemption.

Entry requirements are not identical for every traveler. They may depend on nationality, purpose of travel, and the traveler's eligibility to enter South Korea.

Here is a quick overview:

Purpose of Travel	What You Should Check
Short-term tourism in South Korea	Visa-exemption conditions and K-ETA requirements
Visiting family or attending short-term activities	Entry requirements applicable to the purpose of travel
Working in South Korea	The visa required for the specific type of employment
Studying in South Korea	The visa required for the relevant study program
K-ETA application not approved	Contact the embassy to check the appropriate visa application procedure

Important: Being eligible to enter South Korea without a visa does not mean that you can enter the country without meeting other requirements. Travelers must still comply with immigration regulations and all other applicable entry conditions.

 

What Is K-ETA? How Is It Different from a Visa?

K-ETA stands for Korea Electronic Travel Authorization. It is South Korea's electronic travel authorization system for eligible travelers from visa-exempt countries who are subject to K-ETA requirements.

The system assesses travelers' information before departure. K-ETA is not the same as a visa and cannot replace a visa for every purpose of travel.

The main differences between a visa and K-ETA are summarized below.

Item	Visa	K-ETA
What it is	Authorization under a specific visa category	Electronic travel authorization obtained before departure
Who needs it	Travelers who are subject to visa requirements	Eligible visa-exempt travelers who are required to obtain K-ETA
Purpose	Depends on the type of visa issued	Short-term travel purposes covered by K-ETA
Application method	Apply through the relevant visa application procedure	Apply through the official K-ETA system
Does it guarantee entry?	No	No

For Thai travelers, checking whether they need to apply for K-ETA is an important step before booking and departing for South Korea.

 

Are Thai Citizens Exempt from K-ETA?

South Korea has introduced temporary K-ETA exemptions for certain countries and territories. The temporary exemption measure has been extended until December 31, 2026. However, the exemption does not apply to every nationality.

For Thai passport holders, the guidance provided by the Embassy of the Republic of Korea in Thailand states that travelers visiting for tourism and other purposes covered by the requirements must obtain K-ETA approval before departure unless they qualify for an exemption.

Certain travelers may also qualify for exemptions based on specific criteria, including travelers aged 17 or younger and those aged 65 or older, subject to the applicable rules, as well as other eligible categories.

Before applying, check your individual status through the official K-ETA website to determine whether you need to apply or qualify for an exemption.

How to Apply for K-ETA Before Traveling to South Korea

If you have checked the requirements and confirmed that you need K-ETA, you can apply through the official system. It is best to apply in advance rather than waiting until shortly before departure.

Basic application steps:

1. Visit the official K-ETA website: https://www.k-eta.go.kr/

2. Read the application requirements and check whether you need to apply.

3. Enter your personal information according to your passport and provide any other details requested by the system.

4. Review all information carefully before submitting your application and paying the applicable fee.

5. Check your application status and wait for approval before traveling.

Double-check your English name, passport number, date of birth, and travel information. Incorrect information may require correction or a new application, depending on the system's requirements.

Important: Apply directly through the official channel. Submitting an application successfully does not mean that your K-ETA has been approved.

What Should You Prepare Before Applying for K-ETA?

Prepare the following information and documents before starting your application:

• Passport: The passport you will use to enter South Korea.

• Passport information page: A clear image of the passport information page, if scanning or uploading is required.

• Digital facial photograph: A photograph that meets the system's requirements.

• Email address: An email account that you can access to receive verification messages.

• Current address and contact information: Your up-to-date personal details.

• Flight details and travel dates: Information about your planned trip.

• Accommodation details: The name and address of your hotel or accommodation in South Korea.

• Purpose of travel and accompanying persons: If requested by the system.

• Payment card: A card that supports international online payments.

Make sure your information is current and matches your actual documents. Incorrect information may result in rejection or the need to submit a new application.

Step 1: Visit the Official K-ETA Website

Visit https://www.k-eta.go.kr/

On the homepage, select Apply for K-ETA, then choose the option to begin a new application, if displayed.

Applicants may be able to apply as a member or a non-member. If you prefer not to create a member account, you may choose the non-member option, which requires email verification according to the instructions shown by the system.

Before starting, check whether your passport and purpose of travel fall under K-ETA requirements or an exemption.

 

Step 2: Read the Terms and Conditions and Verify Your Email

Read the terms and conditions carefully, then check the required consent boxes.

If you apply as a non-member, the system will ask you to enter your email address and verify it according to the on-screen instructions. Use an email address that you can access and check your Spam or Junk folder if the verification message does not arrive.

Once your email has been verified, proceed to the passport information section.

 

Step 3: Enter Your Passport Information

This is one of the most important parts of the application because the information must match the passport you will use for your trip.

The system may ask you to enter or confirm the following details:

• Nationality: Your nationality.

• Passport Type: The type of passport you hold.

• Passport Number: Your passport number.

• Surname: Your family name or surname.

• Given Name: Your first name and any other given names as shown in your passport.

• Date of Birth: Your date of birth.

• Sex: Select the option corresponding to your passport information and the available system choices.

• Passport Expiry Date: The expiration date printed in your passport.

The system may allow you to scan or upload your passport information page to read the details automatically. If this option appears, carefully review the information extracted by the system before continuing.

Important tips for entering your name and passport details:

1. Use the English spelling shown in your passport. Do not use a nickname or an alternative spelling.

2. Enter your surname and given name in the correct fields.

3. Check every character of your passport number and the passport expiry date.

4. If the system extracts information automatically from your passport image, do not assume that every field is correct. Review it yourself.

 

Step 4: Enter Your Personal and Travel Information

After completing the passport section, the system will request additional information about you and your travel plans. The fields shown may vary depending on your circumstances and the current application process.

The following information may be requested.

1. Personal Information

Enter the information requested by the system, such as your current address, contact details, occupation, or employment status. Answer truthfully and select the option that best describes your actual situation.

2. Purpose of Entry

If you are traveling for tourism, select the option that corresponds to tourism from the choices displayed. Do not select a different purpose simply because you believe it might increase your chances of approval.

3. Travel Dates

Enter your expected arrival and departure dates according to your actual travel plans. Check the required date format before proceeding.

4. Flight Information

Prepare your flight details, such as your arrival flight and other travel information requested by the system. Make sure the information matches your itinerary.

5. Address of Stay in Korea

Enter the name and address of the hotel or accommodation where you intend to stay. If the system requests contact information for the accommodation, use details that you can verify with the hotel or accommodation provider.

If your accommodation changes after approval, check whether you need to update your travel information in the K-ETA system.

6. Accompanying Persons and Other Information

If you are traveling with family members or friends and the system asks about accompanying persons, answer truthfully. Provide accurate responses to any additional questions about your background or eligibility.

Step 5: Review All Information Before Submitting

After completing the required fields, the system will display a page for reviewing your application before payment.

Use this checklist to review your information:

• Your English name and surname match your passport.
• Your passport number is correct.
• Your date of birth is correct.
• Your passport expiry date is correct.
• Your photograph meets the system's requirements.
• Your purpose of travel is correct.
• Your travel dates and flight information match your plans.
• Your accommodation address and contact information are correct.
• Your email address is correct and accessible.

Important: Do not submit the application if any information is incorrect or uncertain. Errors in important details may require a new application, and application fees that have already been paid are non-refundable under the applicable terms.

 

Step 6: Pay the K-ETA Application Fee

After reviewing your information, proceed to payment according to the instructions displayed by the system.

The K-ETA application fee is KRW 10,000 per person. Additional online payment processing fees may apply. The application fee is non-refundable, even if your application is not approved.

Before paying, check that:

• Your card supports international online payments.

• Your card details and payment verification are correct.

• The amount matches the amount displayed by the system.

• The payment is successful and the system confirms that your application has been submitted.

If a payment error occurs, do not immediately attempt to pay again without checking the status of the original transaction. Verify the application and payment status through the K-ETA system and contact your card issuer if necessary.

 

Step 7: Check Your K-ETA Application Results

After submitting your application and paying the fee, the system may confirm that your submission is complete. However, this does not mean that your K-ETA has been approved.

Return to the official K-ETA website and select Check Application Results. Enter the information requested by the system to view your application status.

Processing generally takes up to 72 hours, although it may take longer in some cases. It is advisable to apply at least one to two weeks before your trip to allow extra time for possible delays.

Once your application is approved, save a copy of the approval details for your records and confirm that the information matches the passport you will use to travel.

If your application is still being reviewed, wait for the result and monitor your status through the official website. Do not assume that successful submission means you are already cleared to board your flight.

 

What Should You Do After Your K-ETA Is Approved?

After receiving approval, review your travel information again, particularly your purpose of entry, travel dates, accommodation, and contact details.

If your travel plans change after approval, check the Update Travel Information menu on the K-ETA website and update your details according to the applicable requirements.

If you obtain a new passport, you must apply for a new K-ETA even if your existing approval has not expired.

In addition, K-ETA approval does not guarantee automatic entry into South Korea. The final decision rests with the immigration officer at the port of entry.
