For knowing whether you need a K-ETA at all
1. Check your landing date against 31 December 2026
K-ETA 한시 면제A K-ETA notice dated 23 December 2025 says the Ministry of Justice extended the temporary K-ETA exemption by one year, from 1 January to 31 December 2026, Korea Standard Time, for the countries and regions already exempt. The Korean Embassy in the United States says the USA is among them. Covered travelers see a pop-up when they scan their passport's information page in the K-ETA application.

The period is set in Korea time, and flights from the Americas cross the date line, so compare both the day you board and the day you land in Korea with it when your trip crosses the new year.
On 24 October 2026 the K-ETA notice board had no notice about arrivals after 31 December 2026.
The K-ETA country list gives a period of stay for each passport, 90 days for the United States. The same site lists those exempt from applying, including visa holders and travelers 17 years old and younger or 65 years old and older on the date of entry.
Plan the first five days after you land.

For deciding what to submit, and when
2. Choose the free e-Arrival Card or a paid K-ETA
전자입국신고서 · K-ETAThe e-Arrival site lists citizens of countries temporarily exempt from the K-ETA among those who submit an arrival card, and says the e-Arrival Card is free and holds the same validity as the paper card. It can be filed on the three days up to and including your arrival date, by Korea time: for a 31 January arrival, 29 to 31 January. A K-ETA costs KRW 10,000 per person, about USD 7–8, plus an online payment fee of generally about 3%, and the K-ETA guide says holders are exempt from submitting the arrival card.

The extension notice says exempt travelers may still apply for a K-ETA, paying the fee, to skip the arrival card, and that an issued K-ETA can be used until it expires. That is worth comparing if you plan to come back: the K-ETA guide gives it a validity of three years for multiple entries, or until the passport expires if that is sooner.
The K-ETA guide says it must be obtained before boarding and that a reissued passport needs a new application. Review typically takes 72 hours or less but can take longer, there is no express service, and the fee is not refunded if the application is refused.
On a phone, one e-Arrival submission covers up to nine people; a group submission on a computer takes up to 1,000. There is no e-Arrival app, only the website.

For the last steps before immigration
3. Keep the issue number and your stay address ready
입국심사After you submit, the e-Arrival Card's issue number is sent to your email, and you can save the card as a PDF. The e-Arrival guide says you need not bring the card to immigration, though knowing the issue number helps, and that it stops being valid 72 hours after submission or once you have passed immigration. If your arrival slips past that point, file again. Source: Korea e-Arrival Card: e-Arrival Card guide

If plans change after you submit, the official site lets you edit the purpose of entry, place of stay or departure date before immigration; the arrival date can be corrected only within three days of the first submission. K-ETA holders update changed travel details on the K-ETA site.
If you did not file before landing, you can still complete the e-Arrival Card or a paper arrival card before immigration.
The form asks for your arrival date and flight number, your place of stay and your departure date; the departure flight number is optional. Since 6 May 2026, submission includes a verification-code step.
Choose a first base and the airport rail line that reaches it.

Questions before visiting
Do I need both a K-ETA and an e-Arrival Card?
Usually not. The e-Arrival site lists K-ETA holders among those excluded from the arrival card, except a K-ETA holder entering on a visa, who completes the e-Arrival Card.
What about children and travelers over 65?
The K-ETA site lists travelers who are 17 years old and younger or 65 years old and older on the date of entry among those exempt from applying. The e-Arrival site lists citizens of K-ETA eligible countries under the age of 17 or over the age of 65 among the people who submit an arrival card.
Can one person file for a family?
Yes. A submission on a phone covers up to nine people. A person aged 14 or younger cannot be the representative declarant.
Which email address should I use?
One you can open while traveling. The K-ETA site posted a notice on 11 March 2026 about delayed email to Gmail users and asks applicants to use another address. The e-Arrival site's notice of 13 March 2026 names Gmail, Outlook.com, Hotmail.com and QQ.com and suggests saving the card as soon as you submit.
Before you go
Use the official sites, k-eta.go.kr for the K-ETA and e-arrivalcard.go.kr for the arrival card. Have your passport, an email address you can open while traveling, your flight number and the full address of your first night's stay. If your trip lands in 2027, check the K-ETA notice board again before you fly.
