Entry requirements
| Requirement | Details | Status |
|---|---|---|
| US visa application B-1/B-2 visitor visa | Apply for a nonimmigrant visa at the US embassy or consulate in your home country. Complete the DS-160 form online, pay the $185 fee, and schedule an in-person interview. Approval is not guaranteed — consular officers have broad discretion to deny.Apply for US visa | Required |
| Valid passport Must cover entire stay | Your South Korean passport must be valid for the full duration of your stay in the United States. US immigration does not enforce a 6-month validity rule, but your airline may check it at check-in. | Required |
| Return or onward ticket Proof of departure from the US | US Customs and Border Protection officers routinely ask for proof of onward travel. Have a printed or digital copy of your return flight or onward ticket ready. If you overstay your visa, you risk a ban from re-entering the US for 3 or 10 years. | Required |
| Proof of accommodation Hotel booking or host invitation | Immigration officers may ask where you're staying. A hotel confirmation or a letter from your US host with their address and phone number works. Not always checked, but saves time if asked. | Recommended |
| Proof of funds Bank statement or credit card | Officers can ask how you'll support yourself during your stay. A recent bank statement showing enough funds for your trip or a credit card with a reasonable limit is sufficient. No specific minimum amount is published. | Recommended |
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 (about $21 USD) 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.
