K-ETA for US Citizens 2026: Do Americans Need a Korea Electronic Travel Authorization?

Do US Citizens Need a K-ETA in 2026? (Quick Answer)

No. As of 6 October 2026, US citizens visiting South Korea visa-free do not need a K-ETA (Korea Electronic Travel Authorization). An extension announced in December 2025 keeps Korea's temporary K-ETA exemption in force until 31 December 2026, Korea Standard Time (KST), and the Korean Embassy in the USA names the United States explicitly.

US passport holders can stay up to 90 days without a visa, according to the official K-ETA list of eligible countries. Employment, study or other paid activity requires a visa from a Korean embassy or consulate.

The exemption does not remove all paperwork. Americans entering without a K-ETA submit an arrival card: the free online e-Arrival Card or a paper card.

Korea has not announced what happens after 31 December 2026. We recommend checking the notice board on k-eta.go.kr before booking any trip that arrives on or after 1 January 2027 (KST).

The K-ETA Exemption for Americans - Dates and Conditions

The K-ETA portal's notice of 23 December 2025 extends the exemption for one more year, from 1 January to 31 December 2026 (KST), for the countries and regions already exempt. A notice from the Korean Embassy in the USA, dated 29 December 2025, confirms that the USA is among them.

What the exemption means in practice:

• It covers visa-free visits only: the 90-day limit still applies, and work or study still needs a visa.
• Exempt travelers are required to file an arrival card, electronic or paper, for each entry.
• A K-ETA remains optional. Exempt travelers can still apply, for example to skip the arrival card, but the fee is then charged. The online form shows exempt nationals a pop-up message.
• A K-ETA you already hold stays usable until it expires, and the fee paid is not refunded.

The exemption is scheduled to end on 31 December 2026 (KST). Unless Korea extends it again, US citizens aged 18-64 traveling visa-free would once more need an approved K-ETA before boarding; as of 6 October 2026 Korea has not announced what happens in 2027.

The notices do not say whether that date counts by boarding or by arrival. Both extensions so far were posted on the K-ETA portal's notice board.

Who Still Needs a K-ETA and How to Apply

For Americans in 2026, the rules below matter mainly for voluntary applicants, and for trips after 2026 if the exemption is not extended. Families of US service members are a special case (see the FAQ).

Standing K-ETA exemptions

Separately from the temporary country exemption, the K-ETA FAQ exempts these groups from applying:

• Travelers aged 17 or younger, or 65 or older, on the date of entry (since 3 July 2023)
• Korean nationals, including dual nationals with a valid Korean passport
• Active-duty US Armed Forces members under the US-ROK Status of Forces Agreement (SOFA)
• Korean visa holders and registered foreigners
• Transfer passengers who do not enter Korea, and cruise travelers
• Flight attendants and seafarers, APEC Business Travel Card holders, and UN, diplomatic or official passport holders

How to apply

According to the official K-ETA website, applications are accepted only at www.k-eta.go.kr or in the K-ETA mobile app. The Korean government has not delegated the service to any agency, and the portal warns about look-alike sites that charge high fees for "agency" or "expedited" applications.

Applicants need a valid passport, email address, ID photo and a credit or debit card; the K-ETA FAQ puts the average time to fill in the form at 10 minutes.

Approval is needed before boarding the flight or ship to Korea. The portal warns that applying after boarding or once in Korea may lead to refusal or entry restrictions.

Fees, Validity and Processing Time

As of October 2026, the official K-ETA pages give these terms:

• Fee: 10,000 KRW per person (about USD 7-8), plus an online payment processing fee of about 3%
• Refunds: none once paid, whatever the outcome
• Validity: 3 years from approval, or until the passport expires if sooner (2 years for applications made before 3 July 2023)
• Processing: typically 72 hours or less, but it can take longer if applications surge

Applications are reviewed in the order received, and there is no expedited service. The K-ETA Center has advised applying well ahead (its 2022 notice suggests 1-2 months before travel).

One K-ETA covers multiple trips while it is valid, but each stay is still limited by the visa-free period, which for US citizens is 90 days. Fees can change, so we recommend confirming them on k-eta.go.kr before paying.

Korea e-Arrival Card and Entry Checks

Korea's Ministry of Justice launched the e-Arrival Card on 24 February 2025. It puts the arrival card online and is a separate system from the K-ETA.

As of 6 October 2026, the official e-Arrival Card site lists citizens of countries temporarily exempt from the K-ETA among those who have to submit an arrival card, which covers Americans in 2026. K-ETA holders are excluded unless they enter on a visa.

How the e-Arrival Card works

• Cost: free
• When: from 3 days before arrival (Korea time) until immigration, even after landing
• Where: only www.e-arrivalcard.go.kr, on PC or mobile web; there is no app, and mobile web takes up to 9 people at once
• What to have ready: passport, email address, arrival date and flight number, address in Korea, and optionally departure details
• Validity: one entry; an unused card lapses 72 hours after submission

A paper card is still accepted, and travelers who did not file online can complete either version before immigration.

The site has warned about fake look-alike websites that demand payment; the real service is free and uses the go.kr government domain.

Entry checks

Neither a K-ETA nor the exemption is a visa, and neither guarantees entry. The K-ETA guide states that a Korea Immigration Service officer makes the final decision at the port of entry.

As of the Ministry of Justice release of 1 October 2026, the United States is not among the 42 countries and regions whose visitors can register on arrival for automated entry gates.

Transit Through Incheon

In 2026 it depends on whether you leave the transit area:

• Staying airside: per the K-ETA and e-Arrival Card FAQs, transit passengers who do not enter Korea need neither a K-ETA nor an arrival card.
• Passing immigration, for example to re-check baggage or join a transit tour: this counts as entering Korea. Nationals who need a K-ETA would need one here, but the exemption covers Americans, so only the arrival card applies.

Same-day transit passengers who pass immigration can give the airport's address as their place of stay: 272 Gonghang-ro, Jung-gu, Incheon (22382) for Terminal 1, or 446 Je2terminal-daero, Jung-gu, Incheon (22382) for Terminal 2.

Incheon Airport Transit Tour

Incheon Airport's transit tours can be joined without a visa. Per the airport's tour page, the layover has to be 24 hours or less, registration takes a passport and boarding passes for both flights, a K-ETA is needed only by nationals outside the temporary exemption, and only one entry into Korea is allowed per visit.

Several courses are free; some charge small entrance fees (USD 3-4 on the airport's course page in October 2026). Programs can change without prior notice.

Korea's separate 30-day visa-free scheme for transfer passengers is for travelers who would otherwise need a Korean visa; US passport holders already enter visa-free for up to 90 days.

Recent Changes (2025-2026)

The rules on K-ETA for US citizens have changed several times since the exemption began on 1 April 2023 for 22 countries and regions, including the US (with Guam), for Visit Korea Year 2023-2024. It was first set to end on 31 December 2024. Since then:

• 11 December 2024: extension to 31 December 2025 (KST)
• 24 February 2025: the e-Arrival Card launched
• 14 March 2025: warning about fake e-Arrival Card sites demanding payment
• December 2025: extension to 31 December 2026 (KST), posted on the K-ETA portal on 23 December and by the Korean Embassy in the USA on 29 December
• 6 May 2026: a verification-code step added to e-Arrival Card submission

As of 6 October 2026, the December 2025 notice is still the latest exemption notice on the K-ETA portal.

FAQ

Do US citizens need a visa for South Korea?

Not for short visits. US passport holders can stay up to 90 days visa-free for tourism, family visits, meetings or business without profit-making. Paid work or study requires a visa from a Korean embassy or consulate.

Will Americans need a K-ETA in 2027?

There is no official answer yet. Unless Korea extends the exemption again, US citizens aged 18-64 traveling visa-free would once more need an approved K-ETA before boarding; as of 6 October 2026 Korea has not announced what happens in 2027.

Is a voluntary K-ETA worth it in 2026?

It is optional. The main benefit is skipping the arrival card for up to 3 years, though travel details on k-eta.go.kr have to be kept current. It costs 10,000 KRW plus about 3% for payment processing, non-refundable even if the application is refused.

Can I still use the K-ETA I already have?

Yes, until it expires, per the December 2025 notice. While it is valid, no arrival card is needed unless you enter on a visa, but changed travel details have to be updated on k-eta.go.kr.

Do I need a new K-ETA after renewing my passport?

Not during the 2026 exemption, unless you want one. The K-ETA FAQ calls for a new application when the passport number or expiry date changes, or your name, nationality, sex, date of birth, infectious-disease or criminal-record information, even if the old K-ETA is still valid.

Do children and travelers over 65 need a K-ETA?

No. Since 3 July 2023, visa-free travelers aged 17 or younger or 65 or older on the date of entry have been exempt. A traveler who turns 18 on the day of arrival needs a K-ETA when no other exemption applies.

Do US service members and their families need a K-ETA?

Active-duty USFK members under SOFA do not; they show a DOD ID card instead of a passport at check-in. Their dependents, and those of civilian-component staff, need one in principle unless they hold a valid A-3 visa or SOFA stamp. The FAQ does not say how the 2026 exemption applies to dependents with US passports, so we recommend checking k-eta.go.kr.

What happens if a K-ETA application is refused?

The K-ETA Center does not give the reason, because the assessment criteria are classified. A traveler who still wants to visit Korea needs a visa from a Korean embassy or consulate.
