Do I Need a Visa to Visit South Korea?

South Korea is a case where the technical rule and the practical rule are different, and it's worth knowing both. On paper, US travelers have needed a K-ETA (an electronic pre-travel authorization) since 2021. In practice, that requirement is currently suspended, and has been for a while — but the suspension has an end date, and it's worth knowing when it comes back. (For US citizens visiting for tourism or short business trips; confirm the current status close to your travel dates, since this has already been extended more than once.)

The short answer for US travelers

Right now, US citizens can enter South Korea for tourism or short business trips for up to 90 days without a K-ETA. The exemption currently runs through December 31, 2026, and it's been extended multiple times since it first started, so this isn't the first time that date has moved. While the K-ETA requirement is suspended, you're not asked for anything in its place except a free e-Arrival Card, filled out online, within 72 hours before you arrive.

The exemption applies to short tourism and business visits. If your purpose is anything else, or your stay would run past 90 days, this exemption doesn't apply and you're into normal visa territory.

What K-ETA actually is, and why it's not stopping you right now

K-ETA is South Korea's version of a pre-travel authorization, similar in spirit to the US's own ESTA — an online application, tied to your passport, meant to be completed before you fly. It's been a real requirement since September 2021, but the government has repeatedly suspended it for a list of countries (the US included) as part of a broader push to make entry easier during a heavy tourism period, most recently extending the exemption through the end of 2026.

You can still apply for a K-ETA voluntarily even while it's not required — one small benefit is that it exempts you from having to file the e-Arrival Card on top of it. For most travelers it's simpler to just skip both and do the free e-Arrival Card, since it takes a few minutes and doesn't require pre-approval.

What changes January 1, 2027

K-ETA is scheduled to become mandatory again for US travelers on January 1, 2027, at which point airlines are expected to check for an approved K-ETA at check-in, the same way UK carriers now check for the UK's ETA. If your travel dates are anywhere near that boundary, confirm the current status before you book rather than assuming the exemption is still in effect — this deadline has been pushed before, but it's not guaranteed to move again.

Before you go

Complete the free e-Arrival Card online within 72 hours of your flight — it's the one thing that is currently required, exemption or not. Confirm the K-ETA exemption is still active for your travel dates on the official K-ETA site before you fly, especially if you're traveling close to the current December 31, 2026 cutoff, and carry standard travel insurance as you would for any trip.

Official sources

Entry rules change, and they depend on your nationality — always confirm the current requirements on the official government site before you book or apply. Only use official government (.gov) portals; ignore look-alike agency sites.
