South Korea Travel Checklist for U.S. Citizens

01 / Entry Requirements

Visa & K-ETA: Before You Board

Good news: entering Korea is easy for U.S. passport holders. No visa is needed for tourism or business stays of up to 90 days, and the K-ETA (Korea's electronic travel authorization) is waived for Americans through Dec 31, 2026.

Passport tip: Korea has no strict 6-month validity rule, but airlines and immigration officers have discretion — renew first if your passport expires soon after your trip.

02 / Money

Money in Korea: Dollars to Won

Korea is one of the most card-friendly countries on earth — Visa and Mastercard work almost everywhere, including taxis and street-level shops. Skip the airport currency counters; if you need cash, ATMs marked "Global" give better rates. A no-foreign-transaction-fee card (Chase Sapphire, Capital One, etc.) is your best travel companion.

03 / If You Need Help

U.S. Embassy in Seoul

The 1330 Korea Travel Hotline is a hidden gem — free 24/7 English help for anything from lost wallets to restaurant directions.

04 / Getting Here

Flights from the U.S. & Culture Tips

Direct flights connect Incheon (ICN) with 10+ U.S. cities — LA, SF, Seattle, NYC, Chicago, Atlanta, Dallas, Honolulu and more — on Korean Air, Asiana, Delta and United. West Coast ~11h, East Coast ~14h.

Time difference: Seoul is 16 hours ahead of the West Coast, 13 ahead of the East Coast. Rule of thumb — your evening is Korea's next morning. Give yourself an easy first day; jet lag from the U.S. is real.

Culture Notes for Americans

Beyond that: shoes off indoors (homes and some traditional restaurants), both hands when receiving something from an elder, and speaking quietly on the subway. Korea runs on 220V with round two-pin plugs (Type C/F) — your phone charger handles the voltage, you just need a plug adapter.

05 / Universal Checklist

Korea Packing Checklist

• eSIM or roamingInstall a Korea eSIM before you fly — cheaper than U.S. carrier roaming and works the moment you land.
• Plug adapter (Type C/F)220V round two-pin. One adapter per device — U.S. flat pins won't fit.
• Naver Map + PapagoGoogle Maps barely works in Korea. Download Naver Map for navigation and Papago for translation.
• e-Arrival CardSubmit online within 72 hours before landing — it replaced the paper form in 2026.
• Kakao T (optional)Korea's Uber. Accepts foreign cards and saves you from taxi-line Korean conversations.

06 / USA × Korea

Old Friends, New Memories

Korea and the United States share one of the closest relationships between any two countries — allies for more than 70 years, since American and Korean soldiers fought side by side in the Korean War. That history is still visible and warmly remembered here: American visitors often find that Koreans, especially the older generation, greet them with genuine gratitude and curiosity. Today the friendship runs both ways — millions of Korean Americans call the U.S. home, and K-pop, Korean food and Korean films have become part of everyday American culture. You're not arriving as a stranger.

A note from me

I spent over two years earning my master's degree in Tulsa, Oklahoma, and it left me with warm memories — the college freshmen driving pickup trucks to campus, the wonderfully kind people all around me. 🎓 When I finished, I drove across the country: Tulsa to Amarillo, Albuquerque, Flagstaff, and finally LA. 🚗 Flagstaff, first glimpsed after crossing the Rockies, was strikingly beautiful, and the thrill of passing through the gateway into California is something I still can't forget. 🏜️ The West Coast highway from Santa Monica to Solvang felt like paradise — if I ever get to live in the States again, I'd want it to be there. 🌴 But Oklahoma stays with me too. I still treasure the evenings I spent chatting with the old gentlemen I met at the casino, and I hope they're all keeping well. 😊 The warmth strangers showed me made my time in America unforgettable. So if you're coming from the States: I hope Korea does for you what America did for me. The kindness I was given is something I now want to pass on. 🤝
