If you're a US passport holder planning a trip to South Korea, here's the reassuring short version for 2026: most travelers don't need a visa, and right now you don't even need a K-ETA. But there's one date worth circling for 2027.
2026: visa-free for up to 90 days
Under the long-standing US–Korea visa-waiver arrangement, American citizens can enter South Korea visa-free for stays of up to 90 days when the purpose is tourism, a short business trip, a conference, or visiting friends and family.
A visa is only required if you plan to:
- stay longer than 90 days, or
- work, study, or settle in Korea.
You'll still clear immigration on arrival and may be asked for a return ticket, proof of accommodation, and sufficient funds.
The K-ETA is temporarily waived in 2026
On top of the visa waiver, Korea has temporarily waived the K-ETA (Korea Electronic Travel Authorization) for designated visa-waiver nationalities — including the US — reportedly through December 31, 2026. So for a 2026 trip, you currently need neither a visa nor a K-ETA for a short visit.
The 2027 change to watch
The K-ETA waiver is a year-by-year measure tied to Korea's tourism push. Reporting indicates the K-ETA is expected to become a mandatory entry requirement again from January 1, 2027 for visa-waiver travelers, including Americans.
If your trip falls in 2027 or later, plan to:
- apply for a K-ETA (around KRW 10,000, roughly US$7–8),
- do it at least 72 hours before departure, and
- use only the official site to avoid look-alike paid services.
What to have ready
- A valid US passport — six months of remaining validity is widely advised, plus a blank page or two.
- A return or onward ticket.
- Proof of accommodation and funds if asked.
Remember: the date that matters is the permitted-until date immigration records at entry. Overstaying — even by a day — can mean fines and a re-entry ban.
Important: visa-free entry is not for work
Visa-free entry and the K-ETA cover tourism, family visits, and short business meetings — not paid employment. Teaching, working, or running a business requires the appropriate visa (such as an E-2 or E-7).
Verify before you book
Entry rules change and depend on your exact situation. Always confirm current requirements on the official k-eta.go.kr, hikorea.go.kr, and the US State Department before booking.
