What is the K-ETA?

The Korea Electronic Travel Authorization (K-ETA) is an online travel authorization that allows travelers from eligible countries to enter South Korea for short-term stays with a simple online application. It was first introduced in September 2021 to simplify the process of entering South Korea and strengthen border security. The K-ETA applies to all countries that do not require a traditional visa to enter South Korea.

Benefits of the Korean ETA include quicker entry into South Korea during immigration clearance, reduced paperwork for both travelers and immigration officials, and a safer country overall. For US passport holders, travelers submit their information online before traveling to South Korea. This lets Korean authorities pre-screen all visitors and improves efficiency. 

The K-ETA does not replace a visa for travelers from countries that still require a traditional visa. It is specifically for visa-exempt countries. If you’re wondering, “Do I need a visa to go to South Korea?”, you should check if you are from a visa-exempt country or if you require a traditional visa.

Do US Citizens Need a K-ETA to Visit South Korea?

Typically, for short-term visits, American citizens are required to obtain a South Korean ETA before traveling to South Korea. However, according to a notice in December 2024, the South Korean government extended a temporary exemption for US passport holders until December 31, 2025. This means that US passport holders currently do not require the K-ETA if they are coming for less than 90 days or less for business or tourism purposes. After December 31, 2025, US passport holders will be required to have a K-ETA to travel to South Korea. If traveling for employment or staying longer than 90 days, a traditional visa is required. 

K-ETA Requirements for US Citizens

When applying for the Korea Electronic Travel Authorization, US passport holders must meet the simple eligibility criteria. 

Valid Passport

A valid passport from a visa-exempt country, like the United States, is required. It must have at least 6 months of remaining validity from the date you plan to enter South Korea.

Online Application Form

The K-ETA application form requires personal information and your travel details. Make sure to fill it out completely and accurately.

Recent Photograph

A digital passport-style photo is required. Make sure it follows the photo requirements specified on the application page.

Application Fee

You can pay the application fee online using a valid payment method, such as a debit or credit card.

Valid Email Address

You will receive information regarding your K-ETA application status via email, so you must have a valid email address.

How to Apply for the South Korea ETA

Even though applying for the Korea Electronic Travel Authorization is a simple process, it is still important to follow each step carefully.

K-ETA Processing Time for US Citizens

The Korean Electronic Travel Authorization (K-ETA) is normally processed very quickly, but it is still advised to apply in advance in case of any unforeseen circumstances that delay your application. For US citizens, it typically takes between 1 and 3 business days for the South Korea ETA to be processed. It is common to receive your approval within 1 day after applying, but as there might be delays, it is best to apply in advance. US citizens are advised to apply at least 72 hours before their departure for South Korea. 

In order to combat any delays in the processing, make sure you double-check all information on the application. Make sure your passport details, flight reservation number, and personal information are correct. A small mistake can cause your ETA to be delayed or even rejected. You may find that during South Korea’s busy season, processing takes longer. During times when the demand for the K-ETA is higher, it is recommended to apply in advance in case there is a shortage of workers in comparison with the number of applications, which may cause delays.

Validity and Duration of Stay

The Korean Electronic Travel Authorization provides US citizens with flexibility when it comes to their travel plans. Once the ETA application has been approved, it is valid for 3 years. It allows for multiple entries and allows each stay to be up to 90 days for American citizens. After you have been in South Korea for a 90-day stay, it is required to exit the country.

It is important to note that if the passport you applied with expires within the 3-year validity period, you must reapply for a new K-ETA with your valid passport. If your travel plans change, such as your purpose for travel, address in South Korea, or expected dates of stay once your Electronic Travel Authorization has been approved, it is required to update this.

Traveling to South Korea with a K-ETA

Once your travel authorization has been approved, it is simple and straightforward to travel to South Korea. The K-ETA is electronically linked to your passport, so you will not be required to present a physical copy when entering the country. It is recommended to bring either a physical or digital copy of your approval in case you run into any unforeseen circumstances during boarding or when entering South Korea. 

When you check in, make sure that you have the same passport that you used to apply for the K-ETA. It is electronically linked to your passport, so you will need to enter South Korea with the passport you applied with. You should also note that your approved K-ETA does not ultimately guarantee access into South Korea. Korean immigration officials have the right to refuse your entry into the country if they choose. 

The e-Arrival Card is required for visitors traveling to South Korea without the K-ETA. Travelers with a valid K-ETA or long-term residents don’t have to fill this out. Since Americans are currently exempt from the K-ETA, they are currently required to complete the e-Arrival Card when entering South Korea, if they don’t hold a valid K-ETA. It is free and must be submitted online within 72 hours before arrival in South Korea; if not used within that window, it becomes invalid and must be resubmitted.

Common Reasons for K-ETA Rejection and How to Avoid Them

It is typical for Korean ETA applications to be approved quickly, but it is not unheard of for applications to be delayed or even rejected. In order to minimize the chances of having issues with the K-ETA application process, you should understand the common mistakes in order to avoid them. 

  • Incorrect or incomplete information – One of the most common reasons that K-ETA applications are rejected is incorrect information. This includes passport details not being correct, such as the wrong passport number, expiration date, or even your name being spelled wrong. Make sure to double-check all of the information before you submit your application.
  • Using an expired passport or a passport that will expire soon – You should have at least 6 months of validity on your passport beyond when you plan on arriving in South Korea. If your passport is already expired or will expire soon, it will likely lead to an automatic rejection. Apply for a new passport and then apply for the K-ETA. If you have applied for the K-ETA and gotten your application approved, and then you get a new passport, you will need to reapply with your current, valid passport. 
  • Uploading photos with poor quality – Make sure to upload your passport-style photo with high quality. Having a blurry photo or shadows in your photo may lead to rejection of your K-ETA application. 
  • Previous immigration or visa violations – If you have a history of overstaying or violating immigration laws (especially in South Korea), you may have your K-ETA application rejected. It is essential to follow all immigration laws to ensure that you don’t break any rules. If you do have a history of overstaying your visa or violating immigration laws, you should apply well in advance to account for possible delays in the processing of your application.

While the application process for the K-ETA is, in general, quite easy, you should still carefully prepare to avoid any of these issues. 

K-ETA for US Citizens - Quick Frequently Asked Questions (FAQs)

For short-term travel for tourism or business purposes, a traditional South Korean visa for US citizens is not required. Instead, they are required to apply for a Korean Electronic Travel Authorization. But in December 2024, the South Korean government extended a K-ETA exemption until the end of 2025 for US citizens. The K-ETA for US citizens is not required in 2025; it will be required again after December 31, 2025.

The K-ETA, or Korean Electronic Travel Authorization, is a travel authorization for passport holders from countries that do not require a traditional visa for South Korea. The system is mutually beneficial for both the convenience of the traveler and the ability to control the border for South Korean immigration control. 

You are only required to have a Korean ETA if you plan on leaving the airport. If you have a layover in South Korea that requires you to pass through immigration, you must have an ETA, but if you aren’t going to pass through immigration, you do not require an ETA.
