Do I Need a Passport for South Korea?

The Short Answer

Yes, you need a valid passport to enter South Korea. The good news: U.S. citizens don't need a visa for stays up to 90 days, and the K-ETA (Korea Electronic Travel Authorization) requirement is currently waived through the end of 2026.

So right now, getting into South Korea is about as simple as international travel gets. Valid passport, a plane ticket, and you're good.

Passport Requirements

Your U.S. passport needs to be valid for the duration of your stay. South Korea doesn't officially enforce a six-month validity rule for U.S. passport holders, but it's still smart to have at least six months of validity remaining. Airlines sometimes enforce their own requirements, and if anything goes wrong during your trip, extra validity gives you a buffer.

Make sure your passport has at least one blank page for entry and exit stamps. South Korean immigration stamps your passport on arrival and departure.

K-ETA: What You Need to Know

The Korean Electronic Travel Authorization (K-ETA) is a pre-travel registration system similar to the U.S. ESTA or Europe's upcoming ETIAS. Here's the current situation:

• Through December 31, 2026: U.S. citizens are exempt from K-ETA. You don't need to apply.
• Starting January 1, 2027: K-ETA will likely become mandatory for U.S. citizens.

Even though it's not required right now, you can still voluntarily apply for a K-ETA. The benefit? It exempts you from filling out the paper arrival card on the plane. If you want to skip that minor hassle, the K-ETA application is available online.

The Arrival Card

Since U.S. citizens don't need a K-ETA right now, you'll need to complete an arrival card. South Korea uses a digital arrival card system, the Q-CODE, which you can fill out online before your trip. Alternatively, you can fill out a paper arrival card on the plane. Doing it digitally beforehand saves time at immigration.

Visa Requirements

U.S. citizens don't need a visa for tourism or business trips of 90 days or less. You'll receive a stamp in your passport on arrival.

You do need a visa for:

• Stays longer than 90 days
• Employment (including teaching English)
• Study programs
• Journalism or media work

If you plan to work or study in South Korea, apply for the appropriate visa at a Korean consulate before your trip. Don't try to enter on a tourist stamp and switch later.

Arriving at Incheon International Airport

Most international flights land at Incheon International Airport (ICN), about 40 miles west of Seoul. It's consistently ranked as one of the world's best airports and the immigration process reflects that.

What to expect:

• Immigration: Present your passport and arrival card (or show your Q-CODE QR code). Officers may ask about the purpose of your visit and where you're staying.
• Customs: You'll go through customs after collecting your bags. If you have nothing to declare, head through the green channel.
• Getting to Seoul: The Airport Railroad Express (AREX) gets you to Seoul Station in about 43 minutes. Taxis and buses are also available.

What About Children?

Children need their own passport to enter South Korea. There's no age exemption. If a child is traveling with one parent, carry documentation showing the other parent's consent. While South Korea doesn't always ask for this, having it prevents potential issues.

Important Things to Know

• Military service: If you hold dual U.S.-Korean citizenship, Korean males may be subject to military service obligations. Consult the Korean embassy before traveling.
• Drug laws: South Korea has zero tolerance for drugs, including marijuana. Penalties are severe even for small amounts.
• SIM cards and Wi-Fi: Pick up a prepaid SIM or portable Wi-Fi device at the airport. South Korea has incredible connectivity, and you'll want data for navigation and translation apps.
• T-money card: Get one at the airport for easy access to subways, buses, and convenience stores throughout your trip.
