What does a US citizen need to enter Korea?

You generally need a US passport valid for the duration of your stay (six months of remaining validity is widely advised), a return or onward ticket, and proof of accommodation and funds if asked at immigration. Many travelers also complete the online arrival/entry reporting before boarding. Always verify current entry steps on the official Korean government sites before you fly.

Can a US citizen work in Korea on a visa-free entry?

No. Visa-free entry and the K-ETA are for tourism, family visits, and short business meetings only — not paid employment. Working, teaching, or running a business in Korea requires the appropriate work or business visa. Working without authorization can lead to penalties and deportation.

Korea Visa for US Citizens (2026)

Q: Do US citizens need a visa to visit South Korea in 2026?

For tourism, short business trips, conferences, or visiting family, US citizens can enter South Korea visa-free for stays of up to 90 days in 2026. A visa is only required if you plan to stay longer than 90 days, or to work, study, or take up residence. Always confirm your specific situation on the official Korea Immigration Service site before booking.

Q: Do Americans need a K-ETA for Korea in 2026?

No. The K-ETA (Korea Electronic Travel Authorization) requirement for US citizens is temporarily waived through December 31, 2026, as part of Korea's tourism push. From January 1, 2027, the K-ETA is expected to become a mandatory entry requirement again for US travelers, so check the official k-eta.go.kr site closer to your trip if traveling in 2027 or later.

Q: How long can a US citizen stay in Korea without a visa?

US passport holders can generally stay up to 90 days per visit under the visa-free agreement. Your exact permitted-until date is recorded by immigration at entry. Overstaying — even by one day — can result in fines and a re-entry ban, so note the date you are admitted until and confirm limits with HiKorea or your nearest Korean consulate.

Short answer: most US visitors do not need a visa in 2026

Under the long-standing visa-waiver arrangement, US 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 to work, study, or settle. On top of that, for 2026 the K-ETA has been temporarily waived for designated visa-waiver nationalities — including the US — reportedly through December 31, 2026.

The 2027 change to watch

The K-ETA waiver is a temporary, 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 is in 2027 or later, plan to apply for a K-ETA (around KRW 10,000, roughly US$7-8) at least 72 hours before departure — and confirm on the official site, because dates and lists can shift.

Which situation applies to you?

1. Visiting for 90 days or less (most travelers)

Tourism, short business meetings, or family visits. In 2026 you may enter visa-free and, for now, without a K-ETA. You will still clear immigration and may be asked for a return ticket, accommodation, and funds.

No visa needed for 2026 short visits

2. Traveling in 2027 or later

Still visa-free for up to 90 days, but you will likely need a K-ETA again. Apply on the official k-eta.go.kr site at least 72 hours before you fly, and only use the official site to avoid look-alike paid services.

Expect K-ETA from Jan 1, 2027 — verify

3. Staying longer than 90 days, or to work/study/live

You need the appropriate visa before or after arrival depending on the category — for example a work, student, or residency visa — and, for stays over 90 days, an Alien Registration Card (ARC) after you arrive.

What to have ready as a US traveler

Item	Notes
US passport	Valid for your stay; six months of remaining validity is widely advised, plus a blank page or two.
Return or onward ticket	Immigration may ask to see proof you intend to leave within the permitted period.
Accommodation & funds	An address where you are staying and reasonable proof of funds if requested.
Online entry reporting	Korea has been rolling out an online arrival/entry reporting step that some travelers complete before boarding. Confirm the current requirement officially before you fly.

The figures above are typical, not guarantees. The permitted-until date that matters is the one immigration records at entry. Overstaying — even by a day — can mean fines and a re-entry ban. Verify on HiKorea.

Important: visa-free entry is not for work

Visa-free entry and the K-ETA are for tourism, family visits, and short business meetings — not paid employment. If you intend to teach, work, or run a business, you need the appropriate visa; see our E-2 teaching visa guide or E-7 work visa guide. Planning to stay past 90 days for any long-term purpose also means registering for a residence card — see the ARC registration guide.

Travel tip, not visa advice: many US visitors set up a local Korean eSIM before they land, so maps, translation, and any verification texts work the moment they step off the plane — useful if you need to show your accommodation address at immigration.
