South Korea Entry Requirements for U.S. Travelers

U.S. citizens can visit South Korea without a visa for up to 90 days for tourism, short business meetings, conferences, or family visits. You need a visa to work or study. Most trips need a passport with enough remaining validity and a free electronic arrival card. If you carry goods above the duty-free limit, you also need a customs declaration.

Two terms come up often. The K-ETA (Korea Electronic Travel Authorization) is an online pre-approval that some visa-free visitors must get before flying. The e-Arrival Card is a free online form that every short-stay visitor files before arrival. U.S. citizens are currently exempt from the K-ETA but still file the arrival card.

Passport validity

Your passport must be valid on the day you arrive. Entry officers refuse travelers whose passports have expired, and airlines check passports at check-in. A torn or water-damaged passport can also be rejected, according to entry guidance for South Korea.

The rule most travelers should plan around is six months of validity beyond the arrival date. Airlines often apply this standard at check-in. Renew a passport that expires within six months of your arrival date before you travel. Bring at least one blank page for the entry stamp.

Visa-free stay and its limits

U.S. citizens can stay up to 90 days without a visa for tourism, short business meetings, attending a conference, or visiting family or relatives. The Korean Consulate General in Los Angeles states that extensions are not permitted, so you must leave before the 90th day. Confirm the current figure on the consulate’s site before you book.

Visa-free entry does not cover working, volunteering, or studying. If you plan a longer stay or any of those activities, you need a visa from a Korean embassy or consulate before you travel. Overstaying can bring fines, detention, and possible deportation.

Applicants who need a visa pay a fee set by the consulate. According to the Los Angeles consulate’s visa fee listing, the fee is US$45 for U.S. citizens regardless of the number of entries. Single-entry visas for stays over 90 days cost US$50 to US$200, and multiple-entry visas cost US$70 to US$250. Processing takes 14 business days, and payment is by cash or money order. Korea no longer issues sticker visas, so you must carry a printed visa certificate to show the officer.

Do U.S. citizens need a K-ETA?

The K-ETA is an online pre-approval for visa-free visitors who do not qualify for an exemption. It is not a visa, and approval does not guarantee entry, because the immigration officer at the port makes the final decision.

U.S. citizens are currently exempt. The e-Arrival Card guide describes the temporary exemption as covering the United States and more than 20 other countries and regions, and it lists the exemption as confirmed through December 31, 2026. Exemptions of this kind change through government announcements, so check the official K-ETA site before you book. If the exemption ends and you need a K-ETA, apply before you board. The official K-ETA guide sets the fee at KRW 10,000, which is about US$7 to US$8. Online payment carries a separate 3% payment fee, and the fee is not refunded if the application is refused. An approved K-ETA is valid for three years or until the passport expires, whichever comes first. Processing usually takes under 72 hours, and no expedited service exists.

A Korean news report from September 2025 described lookalike websites that charged more than 10 times the official fee. Apply only through the official government site.

Filing the e-Arrival Card

The e-Arrival Card is the form every short-stay visitor files, and it costs nothing. The e-Arrival Card guide reports that short-stay foreign visitors without a K-ETA have used the online e-Arrival Card since February 24, 2025. You can file it on a computer or a smartphone.

Submit the card up to three days before your arrival. The Korea Tourism Organization uses Korea Standard Time (GMT+9) for the deadline, so count the window from the arrival date in Korea. If you will stay longer than 91 days, you do not need the card when you hold a valid residence card, a K-ETA, or an e-Group visa. U.S. citizens on the 90-day visa-free allowance are outside that group, so they still file the card, though they do not need a K-ETA.

What border officers check

At the immigration counter, present your passport and your arrival card. Foreign and Korean nationals use separate queues at most entry points, so look for the signs that direct you to the foreign line.

Foreign visitors aged 17 and older must complete fingerprint and facial recognition registration. The Korea Tourism Organization lists exemptions for foreign government officials, representatives of international organizations and their families, and visitors who hold an official invitation from the Korean central government.

Officers may check your face against your passport and ask questions about your visit. Incheon International Airport advises travelers to cooperate with these checks even when they feel inconvenient, because the checks help prevent entry with forged or altered passports. Answer questions about your hotel, the length of your stay, and your purpose for visiting directly and consistently with what you entered on your arrival card.

Duty-free allowances and declarations

The customs limits apply to goods you buy abroad, including duty-free purchases and gifts. Your general allowance is US$800 in total value per traveler. The Korea Customs Service FAQ sets the separate limits below. Travelers under 19 do not receive the liquor and tobacco allowances.

Duty and value-added tax are charged on the value above your allowance. A Korean tax report from October 2025 explains that you must file a customs declaration if you carry goods above US$800 or goods that require separate declaration. If you have nothing to declare, you do not need to fill out a form.

You can submit the declaration through the official app or website before you arrive. The app works on the plane without internet access. The form must be completed in Korean or English, and one form covers your family. Declare alcohol, tobacco, and perfume even when they fall within the allowance, because customs guidance for travelers lists them separately from the general allowance. Travel guidance for Korea makes the same recommendation.

Cash and other payment instruments worth more than US$10,000, or the equivalent in another currency, must be declared. A Korea airline and customs guide lists the same threshold.

Prohibited goods and penalties

Some goods are banned outright. The prohibited list includes narcotics, firearms, ammunition, explosives, obscene material, and counterfeit money and securities. Wildlife, species listed under CITES (the international treaty that restricts wildlife trade), and cultural properties need prior permission or a clearance procedure. You cannot clear these at the counter on the day you land.

Food, medicine, animal and plant products, and commercial goods can require review even when their total value is below US$800. Pre-arrival customs guidance for Korea covers these categories in detail. Two items catch many travelers off guard: beef jerky and fruit. Restricted medications also must be declared. Carry prescriptions and check each medication’s status before you pack it.

Failing to declare dutiable goods adds a 40% surcharge on the tax due, and a repeat offense within two years adds 60%. The Korea Customs Service’s traveler guidance sets these rates. Declaring goods above the limit on your own before the officer finds them reduces the duty by 30%, according to a customs guide published in 2026. Narcotics offenses receive the most serious treatment, so do not bring any controlled substance, even a small amount, without verifying its legal status first.

Entry rules for other nationalities

The rules depend on your nationality. Japan and Taiwan nationals are temporarily exempt from the K-ETA, but they still file the e-Arrival Card. The e-Arrival Card guide also names the United Kingdom, Canada, Australia, Hong Kong, Singapore, and many European nationals among the exempt countries and regions. Those travelers also file the arrival card.

Nationals who need a visa must apply through the nearest Korean embassy or consulate, and the K-ETA does not replace that visa. Holders of a valid Korean visa do not need a K-ETA. Korean citizens, residence-card holders, and aircrew are exempt from the arrival card. Check the exemption list for your own passport on the official Korean government sites before you depart, because the lists change.

Key Takeaways

• Carry a passport valid for at least six months past your arrival date, with at least one blank page for the entry stamp.
• Confirm the K-ETA exemption on the official K-ETA site before you book, since the exemption for U.S. citizens is listed through December 31, 2026.
• File the free e-Arrival Card online up to three days before arrival, even though U.S. citizens are exempt from the K-ETA.
• Declare goods above US$800 and cash above US$10,000, because undeclared dutiable goods carry a 40% surcharge on the tax due.
• Apply for a K-ETA only through the official site and before boarding, since lookalike websites charge far more than the KRW 10,000 official fee.
