US passport holders don't need a visa for South Korea for stays up to 90 days (tourism, business, or short visits). Just make sure your passport is valid for at least 6 months from arrival and has a blank page for the entry stamp.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| Valid passport Must be valid for the duration of your stay | Your passport needs to be valid for the entire time you plan to stay in South Korea. Airlines check this at check-in, and immigration officers at Incheon and Gimhae will deny boarding if your passport expires before your departure date. | Required |
| Return or onward ticket Proof of departure from South Korea | Immigration at Incheon Airport routinely asks for a return or onward ticket. If you arrive without one, they may grant you only a short stay or deny entry. Budget airlines like Jeju Air and T'way Air also check this before letting you board. | Required |
| Proof of accommodation Hotel booking or invitation letter | Have a printed or digital hotel confirmation ready. Immigration officers sometimes ask for your first night's address, and a booking confirmation shows you have a place to stay. Airbnb confirmations work fine. | Recommended |
| Proof of funds Sufficient money for your stay | Carry a credit card and some cash (around 1,000,000 KRW or equivalent). Immigration rarely asks for proof of funds for US passport holders, but having a bank statement or card available covers you if they do. | Recommended |
| K-ETAK-ETA: Korea Electronic Travel Authorization — a digital travel authorization for visa-free visitors. Currently suspended for US passport holders. Korea Electronic Travel Authorization | As of 2025, the K-ETA is temporarily suspended for US passport holders. You do not need to apply for it before travel. If the requirement returns, you will apply online at visa.go.kr for a fee of 10,000 KRW.Apply online | Optional |
Passport validity: 6 months from entry, not departure
Many travelers mistakenly think their passport only needs to be valid for the duration of their stay. South Korea requires at least 6 months of validity from the day you arrive. If your passport expires before that, you will be denied entry — even if your trip is only a week.
Overstay penalties are severe
Don't try to stay even one day over 90. Fines start at around ₩100,000 per day and increase, plus you may be banned from re‑entering Korea for up to several years. Set a calendar reminder to leave a few days early.
What happens at the border
1
Arrive at the airport and go to immigration
After landing at Incheon, Gimpo, or other international airport, follow signs to 'Foreign Passport' immigration. Queues can be busy — expect 15–45 minutes. Have your passport ready.
2
Present your passport and complete entry process
Hand over your passport. The officer may ask your purpose of visit, where you'll stay, and when you'll leave. Answer honestly. For short trips, 'tourism' is usually enough.
3
Submit fingerprints and take a photo
At the booth, place your fingers on the scanner and look at the camera for a digital photo. This is mandatory for all foreign visitors on visa-free entry.
4
Receive entry stamp and proceed
The officer will stamp your passport and return it. Check that the stamp shows the correct date and allowed stay (usually 90 days). Then collect your luggage and head to customs.
