South Korea offers a unique experience for travelers, combining vibrant major cities with tranquil natural landscapes. But before you pack your bags, it's important to understand the entry requirements for South Korea, since these determine whether you'll need a K-ETA, a visa, or nothing at all depending on your nationality.
This guide explains what documentation is required, how to prepare your trip, and what options exist for managing entry authorization depending on your nationality and purpose of travel. Highlights along the way include Gyeongbokgung Palace and Jongmyo Shrine in Seoul, Jagalchi Market and Haeundae Beach in Busan, and the Manjanggul Caves on Jeju Island.
Entry requirements for South Korea
Passport
To enter South Korea, travelers must hold a valid passport with at least 6 months of validity.
Important if a K-ETA is required: it is valid for up to 3 years or until the passport's expiration date, whichever comes first. If the passport is renewed, a new K-ETA will usually need to be obtained.
Visa
Many travelers do not need a traditional visa for South Korea for short stays. Instead, they can enter with a K-ETA (Korea Electronic Travel Authorization), an electronic travel authorization valid for up to 3 years from approval, or until the passport's expiration date, whichever comes first.
South Korea also maintains a temporary K-ETA exemption for certain nationalities and regions until December 31, 2026. Travelers from these countries can enter without applying for a K-ETA during the exemption period, although obtaining one remains optional.
Travelers from other nationalities will need to apply for a South Korea visa instead. For a full breakdown of visa types, required documents, and the K-ETA application process, check out our complete South Korea visa guide.
If your nationality and purpose of travel allow it, you can apply for your K-ETA with Visagov by completing the form, attaching the required documentation, and making the payment; you'll receive approval by email within a few days.
Once you have your K-ETA or visa, you can enter and exit South Korea multiple times during its validity period. The permitted length of stay on each entry depends on your nationality and the admission conditions.
Since February 2025, South Korea has allowed travelers to submit the e-Arrival Card (an online entry declaration), which is free of charge and must be completed within the 3 days prior to arrival. Most travelers must submit it, except in certain cases, such as those holding a valid K-ETA or a residence card.
Upon arrival, travelers must present their passport along with the K-ETA or visa, as applicable. To avoid issues, it's advisable to keep supporting documentation on hand, such as an accommodation booking, onward or return ticket, itinerary, or a letter of invitation if applicable.
Travel insurance
Travel or medical insurance is not mandatory to visit South Korea, but it is highly recommended. Hospital services in Korea are high quality, but they can be expensive.
Medical care is typically provided only after a prior deposit covering the foreseeable cost of services. In some cases, a guarantee declaration from a Korean citizen is required. Comprehensive travel insurance is especially recommended if you're planning higher-risk activities.
Vaccines
South Korea does not require mandatory vaccines to enter the country. Yellow fever is only considered in specific cases linked to the traveler's origin (for example, arrival from areas with known risk), so it's worth checking this based on your itinerary.
Even so, it's advisable to review health recommendations before traveling and make sure your routine vaccines are up to date:
- Chickenpox
- Diphtheria-tetanus-pertussis (DTP/Tdap)
- Influenza (flu)
- Measles-mumps-rubella (MMR)
- Polio
- Shingles
- COVID-19
Depending on the type of trip and traveler, the following are also usually recommended:
- Hepatitis A and B
- Typhoid fever: recommended for most travelers, especially those visiting rural areas or small towns, or staying with residents.
And depending on the specific case:
- Rabies: if contact with animals or higher-risk activities is expected.
- Japanese encephalitis: for long stays or travel to rural areas with greater mosquito exposure.
Malaria is not common in South Korea, though there is a limited seasonal risk in rural areas near the border with North Korea. If you're traveling to a risk area, it may be worth consulting about prophylaxis, and in any case, mosquito-avoidance measures (repellent and long clothing at dawn and dusk) should be applied.
Currency
South Korea's currency is the South Korean won (KRW). Card payment is accepted almost everywhere, but carrying some cash is a good idea for markets, street stalls, or small shops. To obtain won, withdrawing cash from ATMs that accept foreign cards or exchanging at currency exchange offices is usually the most convenient option, since exchange rates at the airport tend to be worse. Some banks may request a passport when exchanging money.
Lastly, keep in mind that tipping is not customary in South Korean culture and may even be considered impolite. With all these requirements sorted out, all that's left is getting the paperwork done ahead of time: if you haven't already, you can start your K-ETA application with Visagov and have everything ready before you board.
