Entry requirements
| Requirement | Details | Status |
|---|---|---|
| ESTA (Electronic System for Travel Authorization)ESTA is an online authorization that allows visa-free travel to the U.S. for up to 90 days. You must have it approved before you travel. Visa waiver entry permit | South Korean citizens must obtain an approved ESTA before boarding a flight to the U.S. Apply online at the official ESTA website (https://esta.cbp.dhs.gov/). The fee is US$40.27 ($4.00 processing + $36.27 authorization). Processing is often instant, but allow up to 72 hours. | Required |
| Passport validityYour passport must not expire soon after your trip. Check the expiration date to ensure it meets the 6-month requirement. Valid for at least 6 months beyond stay | Your South Korean passport must be valid for at least 6 months beyond your intended stay in the U.S. | Required |
| Blank passport pagesYou need an empty page in your passport for the border officer to stamp when you arrive. At least 1 blank page | Your passport must have at least 1 blank page for entry and exit stamps. | Required |
| Return or onward ticketHaving a return flight booked helps show you plan to leave on time, which can avoid questions from airline staff or border officers. Recommended | While not always required at check-in, it is strongly recommended to have a return or onward ticket to demonstrate your intention to leave the U.S. within the 90-day visa-free period. | Recommended |
| Proof of fundsBorder officers may ask how you will pay for your trip. Having proof of funds can make entry smoother. Recommended | Although not mandatory, carrying evidence of sufficient funds (e.g., bank statements, credit cards) is recommended to prove you can support yourself during your stay. | Recommended |
| Arrival declarationYou do not need to fill out any additional arrival form before landing; the ESTA and your passport are sufficient. Not required | No separate arrival declaration is required for South Korean citizens entering the U.S. under the Visa Waiver Program. | Not required |
ESTA is not a visa
ESTA only allows tourism or business visits up to 90 days. You cannot work, study, or live in the US under ESTA. If you plan to do any of those, apply for the appropriate visa before you travel.
Keep your ESTA approval handy
Save a screenshot or printout of your ESTA approval. Airlines check it before boarding, and immigration officers may ask to see it. The ESTA is linked to your passport number, so if you renew your passport, you'll need a new ESTA.
What happens at the border
1
Apply for ESTA online
Go to the official ESTA website (esta.cbp.dhs.gov). Fill in your passport details, travel plans, and answer security questions. Pay the fee (US$40.27) with a credit card. You'll usually get a decision within minutes, but allow 72 hours.
2
Check in for your flight
At the airport, show your valid passport and ESTA approval number. The airline will verify your ESTA status before issuing a boarding pass. Make sure your name matches exactly.
3
Arrive at a US port of entry
After landing, follow signs to 'Arrivals' and then 'US Customs and Border Protection'. You'll queue at a kiosk or with an officer. Have your passport and ESTA confirmation ready. Expect questions about your trip purpose, length of stay, and where you're staying.
4
Clear immigration and collect luggage
Once the officer stamps your passport (or gives you an I-94 record), you're admitted. Collect your bags from the carousel, then proceed through customs. If you have nothing to declare, use the green channel.
