Planning a trip to South Korea? Good news first: US citizens get South Korea 90-day visa-free entry for tourism or business. That covers most travelers, and it's the easiest part of the Korea entry requirements for US citizens in 2026.
But "no visa" doesn't mean "no paperwork." You still need a few travel documents before you board your flight to Incheon. Skip them, and you could face a longer wait at Korea Incheon immigration, or worse, get turned away at check-in.
Below, we'll cover what South Korea visa USA rules actually mean for you, plus the e-Arrival Card and what to expect once you land!
Do US citizens need a visa for South Korea in 2026?

No. US citizens can stay in South Korea for up to 90 days without a visa, as long as you're visiting for tourism or business. This is one of the easiest South Korea entry requirements to meet. It kicks in automatically at the border, so there's nothing extra to apply for.
Visa-free entry works for most common reasons to visit: sightseeing, seeing family or friends, going to a conference, or short business meetings. It doesn't cover work, study, or long-term stays. If your trip falls into one of those categories, you'll need to apply for a visa through the Korean Embassy or Consulate before you travel.
South Korea entry requirements for US citizens at a glance
Here's a quick breakdown of what's required, recommended, or optional for US citizens visiting South Korea in 2026:
Requirement | Required? | Things to Know |
|---|---|---|
Passport | Yes | Must be valid for your entire stay |
Visa | No | For stays up to 90 days |
K-ETA | Not currently required | US citizens are temporarily exempt through December 31, 2026 |
e-Arrival Card | Yes* | Required unless you have an approved K-ETA |
Return or onward ticket | Recommended | May be requested by immigration |
Accommodation details | Recommended | Hotel booking or host address |
Proof of funds | Sometimes | Rarely requested but good to have on hand |
Optional but recommended | Covers unexpected medical costs |
Normally, South Korea asks visitors from visa-free countries to apply for a K-ETA (Korea Electronic Travel Authorization) before they arrive. That rule is on pause for US citizens right now. The K-ETA exemption for 2026 runs through December 31, and K-ETA becomes required again starting January 1, 2027.
How to complete the Korea e-Arrival Card

Since US citizens don't need a K-ETA right now, the e-Arrival Card takes its place. It's free, quick, and easy to fill out on the official Korea e-Arrival Card website. Here's how to get it done:
Step 1: Enter your email address and accept the terms and conditions to start.
Enter your passport info. Type in your valid passport details.
Step 2: Add your arrival and departure dates and where you're staying.
Step 3: Look everything over before you submit, since mistakes can slow things down.
Step 4: Once it goes through, you'll get a confirmation. Screenshot it or save the PDF to your phone, and try to do all this a day or two before you fly so you're not stuck hunting for Wi-Fi at check-in.
Documents US citizens should prepare before traveling to Korea
Valid passport
Your passport needs to stay valid for your whole trip. Unlike some countries, Korea doesn't ask for six extra months of validity past your travel dates. Still, it's smart to renew early if yours is close to expiring. Passport validity is one of the first things an immigration officer checks, so don't leave it to chance.
Return or onward flight ticket
Your visa-free stay is capped at 90 days. Proof of when you're leaving (or where you're headed next) helps show your trip fits inside that window. Keep a digital or printed copy of your itinerary on hand.
Accommodation confirmation
A hotel booking or the address of where you're staying (like a friend's place) is one of the most common things immigration asks for. It's an easy one to prepare, so save it on your phone before you land.
Proof of sufficient funds
This one's rarely requested, but it doesn't hurt to have a bank statement or account balance ready just in case. Think of it as a backup, not something you'll need at every stop.
Completed e-Arrival Card
Since K-ETA isn't required for US citizens right now, the e-Arrival Card is your main piece of digital paperwork. Submit it within 72 hours of arrival and keep your confirmation saved.
What happens at South Korean immigration?

Landing at South Korea is pretty simple once you know what to expect. Here's the rundown, step by step:
- Passport check: An officer scans your passport, just like at most international airports.
- Photo or fingerprint scan: Some travelers get asked for this as an extra security step. It's quick and nothing to worry about.
- A few quick questions: Officers might ask why you're visiting, how long you're staying, where you're staying, and about your return flight. These are routine, so keep your answers simple.
- Baggage claim: Grab your bags once you're through the passport check.
- Customs: If you're not bringing in anything that needs to be declared, head straight for the green "nothing to declare" lane and you're done.
