Q: Do U.S. citizens need K-ETA in 2026?

No. The K-ETA exemption for U.S. passport holders is extended through 31 December 2026. Starting 1 January 2027, K-ETA is required unless the policy changes.

Q: Can I work on visa-free entry?

No - tourism and short business meetings only. Work requires a visa class (D-7, E-1 to E-7, H-1) with sponsorship.

Q: Direct flights from US?

Yes - KAL, Asiana, UA, DL, AA serve LAX/SFO/SEA/ORD/ATL/DFW/JFK direct to Incheon.

Q: What if my K-ETA is denied?

Americans can visit South Korea visa-free for up to 90 days for business or tourism. K-ETA is exempt through 31 Dec 2026, then required from 1 Jan 2027. U.S. passport holders can visit South Korea visa-free for up to 90 days for business or tourism. The Korean Electronic Travel Authorization (K-ETA) exemption for U.S. passport holders has been extended through 31 December 2026; from 1 January 2027, K-ETA is required before travel. During the exemption, travelers may still apply voluntarily for K-ETA to skip submitting an arrival card, in which case the KRW 10,000 fee applies. Approved K-ETA is valid for 3 years, or until passport expiry if earlier, and can be used for multiple entries. The U.S. State Department says U.S. passports only need to be valid at the time of entry, with no minimum expiration validity requirement. Work, teaching English, study, journalism, and stays longer than 90 days require an appropriate visa before travel. Exceeding authorized stay can lead to exit bans, detention, fines, deportation, and future entry problems.
