South Korea Entry Requirements for US Citizens: K-ETA & Visa Explained

Until the end of 2024, US citizens had it unusually easy — the K-ETA requirement was temporarily waived, meaning Americans could board a flight to Seoul with just a valid passport and a hotel booking. That waiver expired on December 31, 2024. As of January 1, 2025, and continuing through 2026, US citizens are once again required to obtain a K-ETA before arriving in South Korea for short stays. Many travelers are still searching for outdated information that says the waiver is active. It is not. Here is exactly what you need to do before you fly.

What Changed for US Citizens in 2025–2026

South Korea’s immigration agency ran a temporary K-ETA exemption from April 1, 2023 through December 31, 2024 for citizens of 22 countries, including the United States. The goal was to encourage post-pandemic tourism recovery. That program has ended, and no extension has been announced for 2026.

What this means in practical terms: if you are a US citizen planning a trip to South Korea in 2026 for tourism, a business meeting, or a family visit of under 90 days, you must apply for a K-ETA before departure. You cannot get one at the airport. Airlines are required to verify your K-ETA status at check-in, so showing up without one means you do not board the plane.

The good news is that the K-ETA is inexpensive, takes under 20 minutes to apply for, and is valid for two years with multiple entries. Most travelers approved once will not need to apply again for their next trip to Korea within that window.

How to Apply for K-ETA: Step-by-Step

The official K-ETA platform is www.k-eta.go.kr. There is also an official K-ETA mobile app available on iOS and Android. Avoid third-party websites that charge inflated fees to submit the same form — the official fee is KRW 10,000 (approximately USD 7.50) and nothing more.

1. Go to the official site or open the app. Select “Apply for K-ETA” and choose United States as your nationality.
2. Upload your passport bio-data page. Take a clear, well-lit photo of the page with your photo and personal details. Blurry uploads cause rejections.
3. Enter personal and travel information. This includes your full legal name as it appears on your passport, date of birth, gender, and passport number. You will also enter your intended arrival date and an address in South Korea — a hotel name and address is fine.



4. Upload a passport-style photo. The photo must be in color, on a plain background, front-facing, with no hats or sunglasses. File size must be under 100KB, and dimensions should be 700×700 pixels. Resize your photo before uploading if needed.
5. Answer the security questionnaire. Questions cover criminal history and health-related disclosures. Answer accurately.
6. Review everything carefully. A name that doesn’t match your passport, or a wrong passport number, will cause denial.
7. Pay the fee. KRW 10,000 (~USD 7.50–8.00). Accepted cards include Visa, MasterCard, American Express, JCB, and UnionPay. Your bank may add a small foreign transaction fee.
8. Submit and wait. You will receive the decision by email. Save or print the approval document and keep it accessible at check-in.

Your approved K-ETA is valid for two years from the approval date, or until your passport expires — whichever comes first. It allows multiple entries, as long as each individual stay does not exceed 90 days. If your K-ETA is denied, you must apply for a short-term C-3 visa at a Korean consulate in the US; denied K-ETA applicants cannot re-enter via K-ETA on that same passport.

The e-Arrival Card (Q-code): What It Is and Why You Should Use It

Separate from the K-ETA, South Korea’s Korea Disease Control and Prevention Agency (KDCA) operates a web-based health declaration system called the Q-code. The website is cov19.kdca.go.kr. There is no dedicated app — you access it through a mobile browser or your computer.

Mandatory quarantine requirements were fully lifted in 2022, and there is no pre-departure COVID-19 PCR test required. The Q-code now functions as a digital health screening tool that makes the quarantine checkpoint at the airport essentially a two-second QR scan rather than a paper form handoff. It is not strictly required by law, but skipping it means you will fill out a paper form in line at the airport while the travelers who pre-registered walk straight through. The line difference is noticeable — especially on busy flight days at Incheon Terminal 1 when multiple international flights land within the same hour.

To use it, fill in your passport details, flight number, seat number, arrival date, Korean contact address, and a brief health status summary covering the past 21 days of travel. Submit the form and a QR code is generated. Screenshot it or save it to your phone’s photo library so you can pull it up even without Wi-Fi when you land.

When You Need a Visa Instead of K-ETA

The K-ETA covers tourism, family visits, short business meetings, and non-profit event participation — all for stays under 90 days. Anything outside those parameters requires a visa obtained before you travel. The Korean Embassy in Washington D.C. (www.us.korean-culture.org) handles applications, as do Korean Consulates General in New York, Los Angeles, San Francisco, Chicago, Houston, Atlanta, Seattle, Honolulu, and Boston. Which consulate has jurisdiction over you depends on your state of residence.

Common Visa Types for US Citizens

• C-3 (Short-Term General): Used when a K-ETA has been denied, or the purpose of visit does not qualify for K-ETA. Up to 90 days.
• D-2 (Student): For enrollment in a Korean university or graduate program.
• D-4 (General Training): For Korean language programs and exchange students not enrolled in a degree course.
• E-series (Work Visas): Categories E-1 through E-7 cover specific professions — English language instructors (E-2), arts and performance (E-6), and skilled workers in designated fields (E-7) among them.
• F-series (Long-Term/Family): For spouses of Korean nationals, dependents of residents, or long-term visitors with qualifying ties to Korea.

Typical documents required for any visa application include: a valid US passport with at least six months of validity beyond your intended stay, a completed visa application form, passport-sized photos, proof of purpose (invitation letters, enrollment documents, employment contracts), financial statements, proof of accommodation, and a return or onward ticket. Processing times range from a few business days for simple short-term visas to several weeks or months for long-term and work visas. Apply early.

What Happens at Incheon Airport: The Full Arrival Sequence

Incheon International Airport (ICN) is where the vast majority of US-to-Korea flights land. Here is what the arrival process actually looks like, in order.

1. Health screening checkpoint. After leaving your gate, you will pass thermal cameras monitoring for fever. If you have your Q-code QR code ready, an officer scans it in seconds and waves you through. Without it, you fill out a paper form here. The faint antiseptic smell of the checkpoint area is a consistent feature of every Incheon arrival, as is the polite but efficient pace of the uniformed KDCA staff directing foot traffic.
2. Immigration — Foreigner booths. Present your US passport and K-ETA approval (digital or printed) to the immigration officer. Both fingerprints and a facial scan are taken. The officer may ask standard questions: purpose of visit, where you are staying, how long you plan to remain. Answer simply and directly. South Korea stopped physically stamping most tourist passports — your entry is recorded digitally.
3. Automated gates (SES). Incheon has Smart Entry Service automated immigration lanes, but these require prior registration, which is typically done during an earlier visit to Korea. Most first-time US visitors will use the staffed booths.
4. Baggage claim. Check the overhead monitors for your flight number and the assigned carousel number. Luggage from long-haul US routes typically takes 15–25 minutes to appear.
5. Customs declaration. South Korea’s customs service has a Traveler’s Customs Declaration mobile app (available on iOS and Android) that lets you complete your declaration before landing and generates a QR code. If you use the app, you scan out through the customs lane quickly. If not, you take a paper form — available on the plane or at the airport — and hand it to the customs officer. Proceed through either the “Nothing to Declare” or “Goods to Declare” lane as appropriate for what you are carrying.

Mistakes That Get US Travelers Turned Away

These are the actual errors that cause real problems at check-in counters and immigration booths — not hypothetical edge cases.

• Applying for K-ETA too late. If you apply 12 hours before your flight and your application goes to manual review, you will not board. Apply at least a week early.
• Name mismatch on K-ETA. Your K-ETA must match your passport exactly, including middle names if printed on the passport. A hyphen in the wrong place or a missing initial is enough to cause a problem at the immigration booth.
• Expired passport. Your passport must be valid for at least six months beyond your intended departure date from Korea. A passport expiring two months after you plan to leave will be rejected.
• No return or onward ticket. Immigration officers can and do ask to see proof that you are leaving. Having a booked return flight accessible on your phone is the simplest solution.
• Using a third-party K-ETA service. Multiple websites impersonate the official K-ETA portal and charge USD 40–70 to submit the same application you can file yourself for USD 7.50. Worse, some of these sites have caused delays or errors that resulted in denial.
• Overstaying a previous visit. If you overstayed a prior K-ETA or visa, a future K-ETA application will almost certainly be denied, and a visa will require additional documentation to address the prior overstay.

2026 Budget Reality: What Entry Will Cost You

Entry into South Korea is not expensive, but there are several fees to account for before you budget for flights and accommodation.

• K-ETA fee: KRW 10,000 (~USD 7.50–8.00). One-time cost, valid two years with multiple entries. Your bank may add a small foreign transaction fee of USD 0.50–1.00.
• Q-code (e-Arrival Card): Free. No fee to complete the health declaration.
• C-3 short-term visa (under 90 days): Approximately USD 45–50, payable by money order or cashier’s check at the consulate.
• C-3 or general visa (over 90 days, single-entry): Approximately USD 75–80.
• Multiple-entry visa: Approximately USD 100–120.
• Customs declaration app: Free to download and use.

For the overwhelming majority of US tourists visiting Korea in 2026, the only entry cost is the KRW 10,000 K-ETA fee. Everything else is either free or only relevant if your situation requires a full visa.

Frequently Asked Questions

Do US citizens still need a K-ETA in 2026?

Yes. The temporary K-ETA waiver for US citizens expired on December 31, 2024. As of January 1, 2025, and continuing into 2026, US citizens must apply for a K-ETA before boarding any flight to South Korea for short-term stays under 90 days. The official application site is www.k-eta.go.kr.

How long does K-ETA approval take?

Most K-ETA applications are approved within 24 to 72 hours. Some are flagged for manual review and can take several days longer. Always apply at least one week before your departure date to leave enough buffer. You cannot apply at the airport or on arrival.

Can I enter South Korea without a K-ETA if I have a valid US passport?

No. Since the waiver ended in January 2025, a valid US passport alone is not sufficient for visa-free entry. You need both a valid passport and an approved K-ETA. Airlines check K-ETA status at check-in and will deny boarding without it.

What is the Q-code and is it mandatory?

The Q-code is South Korea’s digital health declaration system, accessed at cov19.kdca.go.kr. It generates a QR code that speeds up the quarantine checkpoint at the airport. It is not legally mandatory, but skipping it means filling out a paper form in line at the airport, which slows down your arrival process noticeably.

What happens if my K-ETA application is denied?

A denied K-ETA means you cannot enter South Korea under the visa-waiver system on that passport. You must apply for a C-3 short-term visa at a Korean Embassy or Consulate in the US. Contact the consulate with jurisdiction over your state of residence. Fees are approximately USD 45–50 for single-entry stays under 90 days.
