Jeju Island, South Korea's most popular domestic and international destination, welcomes millions of visitors each year with a relatively straightforward entry process. As a Special Autonomous Province, Jeju benefits from its own visa waiver program that is more permissive than mainland South Korea's general immigration policy, allowing citizens of most countries to enter directly through Jeju International Airport (CJU) or Jeju seaports without a visa for short stays. This makes it one of the most accessible island destinations in Northeast Asia, and a natural starting point for exploring South Korea before or after planning a jeju itinerary. Travelers arriving directly into Jeju from abroad are subject to Jeju's special visa-free program, which permits stays of up to 30 days for tourism. However, if you plan to visit Jeju as part of a broader South Korea trip, entering through Incheon (ICN) or Gimpo (GMP) first and then flying or taking a ferry to Jeju, the standard South Korean immigration rules apply to your initial entry. In that case, many nationalities enjoy 90-day visa-free access to all of Korea, including Jeju. Regardless of entry point, all visitors must hold a valid passport, carry proof of onward travel, and have sufficient funds for their stay. South Korea's immigration officers conduct professional and efficient checks. Understanding the distinction between Jeju's local waiver and mainland Korea's visa policy is the single most important thing to clarify before you travel, if you plan jeju day trips to nearby islands or a broader Korean itinerary.

Visa Requirements

Entry permissions vary by nationality. Find your category below.

Jeju Island operates under a dual-layer visa framework. Its own Jeju Visa Waiver Program (JVWP) grants visa-free entry directly into Jeju for citizens of most countries. Separately, South Korea's national visa policy governs entry through mainland ports and applies when Jeju is part of a broader Korean trip. Both systems are generous by regional standards. But they are distinct, and knowing which applies to your itinerary is essential.

Visa-Free Entry, Jeju Special Waiver (Direct Arrivals)
Up to 30 days

Citizens of most countries worldwide can enter Jeju without any visa when arriving directly at Jeju International Airport (CJU) or via Jeju seaports. This Jeju Visa Waiver Program is a deliberate policy to support Jeju's tourism economy and its status as a free international city. Visitors under this program are permitted to stay in Jeju only, if you wish to travel to mainland South Korea during the same trip, you must meet mainland visa requirements.

Includes
United States United Kingdom Canada Australia New Zealand Germany France Italy Spain Netherlands Belgium Sweden Norway Denmark Finland Austria Switzerland Portugal Ireland Luxembourg Greece Czech Republic Poland Hungary Japan Taiwan Hong Kong (SAR) Singapore Malaysia Thailand Indonesia Philippines Vietnam India Brazil Mexico Argentina Chile South Africa and most other nations

The Jeju waiver applies ONLY when arriving directly into Jeju (CJU airport or Jeju seaports). It does not permit onward travel to mainland Korea unless you separately qualify under South Korea's national visa policy. Visitors must hold a return or onward ticket and proof of accommodation. Stay is limited to 30 days for tourism. Work and study are not permitted.

Visa-Free Entry, South Korea National Policy (90 Days, All Ports)
Up to 90 days (tourist/short-stay)

Many nationalities benefit from South Korea's bilateral visa-free agreements, granting 90-day visa-free entry through any Korean port of entry, including Incheon International Airport (ICN). Travelers in this category can visit both mainland South Korea and Jeju freely within their 90-day allowance. This is the most flexible entry option for planning a complete South Korea and Jeju trip.

Includes
United States United Kingdom Canada Australia New Zealand All EU/Schengen member states Japan Singapore Hong Kong (SAR) Taiwan Israel Brazil Mexico Chile and approximately 110 total countries

Visa-free stays are for tourism, business visits, and transit only. Employment, study, or long-term residence require appropriate visas. The K-ETA (Korea Electronic Travel Authorization) requirement for visa-free travelers was introduced in 2021 and then suspended for many nationalities, check immigration.go.kr for current K-ETA status for your passport before travel.

K-ETA (Korea Electronic Travel Authorization)
Valid for 2 years or until passport expiry. Each stay up to 90 days

South Korea's K-ETA is an electronic pre-travel authorization required for certain visa-exempt nationalities entering through mainland Korean ports. It is NOT required for the Jeju direct-arrival waiver. The K-ETA requirement has been subject to multiple temporary suspensions, many Western nationalities have been exempt from the K-ETA requirement during suspension periods. Always confirm the current status for your nationality before booking.

Includes
Applies to select visa-exempt nationalities entering via mainland Korean airports, check k-eta.immigration.go.kr for the current country list
How to Apply: Apply online at k-eta.immigration.go.kr. The process is fully digital: upload a passport photo, provide travel details, and pay the fee. Most applications are approved within 72 hours, though the system typically returns decisions within minutes.
Cost: Approximately KRW 10,000 (around USD 7, 8)

K-ETA is not required if you are entering directly into Jeju under the Jeju Visa Waiver Program. It may be required if you enter mainland Korea first (e.g., via Incheon) and then fly to Jeju. Check the current suspension status at the official K-ETA portal, as of early 2026, the suspension covered many OECD-member nationalities.

Visa Required
Varies by visa type. Tourist visas typically 90 days

Citizens of countries not covered by Jeju's waiver program or South Korea's national visa-free agreements must obtain a visa before travel. Certain nationalities are explicitly excluded from the Jeju Visa Waiver Program for security reasons and require a visa regardless of entry point.

How to Apply: Apply at the nearest Korean embassy or consulate in your home country. Required documents typically include a completed application form, valid passport, passport-sized photograph, proof of financial means, travel itinerary, and accommodation details. Processing typically takes 3, 10 business days. Online visa applications are available for some nationalities through the HiKorea portal (hikorea.go.kr).

Countries excluded from the Jeju Visa Waiver Program (and therefore requiring a visa even for direct Jeju arrivals) include Afghanistan, Iraq, Iran, Libya, Syria, Sudan, Yemen, Nigeria, Kosovo, and several others designated by the Korean government. Citizens of these countries must hold a valid South Korean visa before travel. Check the Korea Immigration Service website for the current exclusion list.

Arrival Process

Arrival at Jeju International Airport is generally smooth and efficient. The airport handles both domestic and international flights, and the international arrivals hall is compact and well-signposted. Peak travel periods, during cherry blossom season (late March, April), summer holidays (July, August), and the autumn foliage season, see significantly higher passenger volumes, so budget extra time. For the best time to visit Jeju for crowd management, spring and autumn arrivals are popular. Arriving early morning on weekdays moves the fastest.

1
1. Aircraft Arrival and Disembarkation
After landing at Jeju International Airport (CJU), follow signage to the international arrivals area. Jeju's airport is a single terminal building. The walk from gate to immigration is typically under 10 minutes. Quarantine checks may be in place for travelers arriving from certain regions, these are usually quick health declaration screenings.
2
2. Health and Quarantine Screening
Proceed through any active health screening checkpoints. As of 2026, South Korea does not require COVID-19 vaccination certificates or testing for entry. However, travelers showing symptoms of infectious illness may be subject to additional screening. Complete any required health declaration forms, these may be submitted digitally via the Visit Korea mobile app before arrival.

3. Immigration (Entry Inspection)
Present your passport to an immigration officer. Korean immigration officers are thorough but efficient. You will have your photograph taken and fingerprints scanned at the counter (part of South Korea's standard biometric enrollment for foreign visitors). Have your boarding pass, return ticket, and accommodation details ready. Most entries are processed in 1, 3 minutes per traveler.
4
4. Baggage Claim
Collect your checked luggage from the baggage carousel. Carousel assignments are displayed on screens throughout the arrivals hall. If luggage is delayed or missing, report immediately to the airline's baggage service desk before leaving the arrivals area.
5
5. Customs Declaration
Pass through customs inspection. Travelers with nothing to declare use the green channel. Those carrying goods above duty-free limits, currency exceeding USD 10,000 equivalent, restricted items, or commercial goods must use the red channel and complete a customs declaration form. Random inspections are conducted in the green channel as well.
6
6. Arrivals Hall, Transportation
Exit into the public arrivals hall where you will find taxi ranks, bus stops, car rental counters, and tourist information. The Jeju Tourist Information Center at the airport can provide maps, transportation guidance, and accommodation assistance.

Documents to Have Ready

Valid Passport
Must be valid for the duration of your stay. South Korean immigration recommends at least 6 months of remaining validity beyond your intended departure date, though the formal requirement is validity through your stay. Ensure the biographical data page is undamaged and readable.
Return or Onward Ticket
Immigration officers routinely ask to see evidence that you intend to leave Korea before your permitted stay expires. A printed or digital confirmation of your return or onward flight is sufficient. Travelers entering under the Jeju 30-day waiver should ensure their ticket shows departure within 30 days.
Proof of Accommodation
A hotel booking confirmation, Airbnb reservation, or letter of invitation from a Korean host. Having this ready, either printed or on your phone, speeds up the immigration process. Officers for Jeju entries occasionally ask, for travelers arriving without a pre-confirmed hotel.
Proof of Sufficient Funds
Immigration may ask for evidence that you can support yourself financially during your stay. A credit card in your name plus a small amount of cash is generally sufficient. No specific minimum amount is formally defined. But KRW 100,000 (approximately USD 75) per day is a reasonable guideline.
K-ETA Approval (if applicable)
If your nationality requires a K-ETA for your specific entry port (not applicable for direct Jeju arrivals under the Jeju waiver), carry the approval confirmation. Airlines may check this at check-in. The approval is electronic, screenshot or PDF is acceptable.
Visa (if required)
Citizens of countries excluded from both the Jeju waiver and Korea's visa-free agreements must have a valid Korean visa stamped or affixed in their passport before travel. Electronic visas (e-Visas) issued through HiKorea are printed confirmations, carry the printout.

Tips for Smooth Entry

Complete the Korean immigration arrival card (if distributed on your flight) neatly and in English or Korean. Some airlines distribute these on board, fill it out before landing to save time at immigration.
Download the Visit Korea app before departure. It can store your travel details, health declaration information, and is a useful reference during the arrival process.
Have your hotel confirmation and return ticket accessible on your phone before joining the immigration queue, fumbling for documents is the most common cause of delays at the counter.
Korean immigration maintains separate lanes for Korean nationals, diplomatic passport holders, and foreigners. Use the 'Foreigners' lane clearly marked in English. Automated e-gate kiosks may be available for eligible passport holders enrolled in the fast-track program.
Jeju's airport is compact. Even during peak periods, the full arrival process from landing to exiting the terminal rarely exceeds 45 minutes for straightforward cases. Budget more time during major Korean holidays (Chuseok, Seollal) when the airport is exceptionally busy.
If you are planning to use Jeju as a transit point and then continue to mainland Korea, verify that you meet South Korea's national entry requirements, the Jeju 30-day waiver does not automatically grant permission to enter the mainland.

Customs & Duty-Free

South Korean customs regulations apply uniformly to all international arrivals, including those entering through Jeju. South Korea uses a two-channel customs system (red channel for declaration, green channel for nothing to declare) and employs X-ray screening and detector dogs. Jeju has no special customs zone separate from South Korea's national customs system, the island's 'free international city' designation refers to its visa policy, not a duty-free import regime for residents. Travelers should be aware that South Korea enforces strict agricultural and biosecurity controls, and the importation of certain food items is heavily restricted to protect domestic agriculture.

Alcohol
1 bottle (up to 1 liter) duty-free. Value must not exceed USD 400.
Must be for personal use only. Travelers under 19 years of age (Korean age system, check your eligibility) are not entitled to the alcohol allowance. Amounts above 1 liter are subject to customs duty and liquor tax.
Tobacco
200 cigarettes (1 carton), or 50 cigars, or 250g of other tobacco products, one category only.
The allowance applies to one category, not combinations. Travelers under 19 years of age are not entitled to the tobacco allowance. E-cigarette liquids and heated tobacco products are subject to specific regulations, declare if unsure.
Perfume
60ml (2 oz) of perfume
Part of the general personal effects allowance. Larger quantities should be declared.
Currency
Amounts of KRW 10,000,000 (approximately USD 7,500) or equivalent in foreign currency must be declared.
There is no limit on currency you can bring in or take out of Korea. But amounts meeting the declaration threshold must be reported at customs. Failure to declare is an offense subject to confiscation and fines.
Gifts and Personal Goods
Goods with a combined value of USD 800 (approximately KRW 1,000,000) are exempt from duty.
This allowance is for personal use items and gifts, not commercial goods. Items purchased duty-free at your departure airport or on board count toward this limit. Goods above the threshold are subject to customs duty at applicable rates.

Prohibited Items

  • Narcotics, psychotropic substances, and cannabis (including CBD products from countries where cannabis is legal, Korean law applies regardless of origin)
  • Firearms, ammunition, and explosives without prior authorization from the Korean National Police Agency
  • Counterfeit currency, forged documents, and fraudulent credit cards
  • Publications, films, or media that threaten public order, national security, or public morals as defined by Korean law
  • Items infringing intellectual property rights (counterfeit goods, pirated media)
  • Live animals and animal products without valid health certificates and import permits, strict for poultry and pork products due to avian influenza and ASF concerns
  • Raw fruits, vegetables, seeds, and soil without phytosanitary certification, South Korea enforces strict agricultural biosecurity at all entry points
  • Products made from endangered species listed under CITES without documentation

Restricted Items

  • Prescription medications, bring a doctor's letter in English for any controlled substance or injectable medication. Quantities exceeding a 90-day personal supply require import approval from the Ministry of Food and Drug Safety
  • Hunting rifles and sports firearms, require advance import permits from the National Police Agency. Contact the Korean embassy in your country before travel
  • Communication equipment (satellite phones, specific radio devices), may require prior approval from the Ministry of Science and ICT
  • Cultural properties and antiques, items of potential historical or cultural significance may be subject to export/import controls. Obtain certificates of origin where possible
  • Certain food products from animal sources (dairy, meat), subject to strict biosecurity controls. Declare all food items at customs even if you believe they are permitted

Health Requirements

South Korea, including Jeju, currently imposes no mandatory vaccination requirements for entry from most countries. The country successfully managed its COVID-19 response and has removed pandemic-era entry restrictions. Jeju's subtropical climate and developed healthcare infrastructure mean health risks for visitors are low by international standards. That said, travelers should ensure their routine vaccinations are current and consult a travel medicine specialist for personalized advice based on their health history and specific activities planned.

Required Vaccinations

  • Yellow Fever vaccination certificate required only for travelers arriving from Yellow Fever endemic countries (primarily sub-Saharan Africa and parts of South America). If your journey originates from or transits through an endemic country, carry your International Certificate of Vaccination or Prophylaxis (ICVP, 'yellow card').

Recommended Vaccinations

  • Hepatitis A, recommended for all travelers. Transmission possible through contaminated food or water
  • Hepatitis B, recommended for travelers who may have medical procedures, close contact with locals, or sexual exposure
  • Typhoid, recommended for adventurous eaters or those staying in less-developed areas. Risk is low but present
  • Japanese Encephalitis, recommended for travelers spending extended time in rural areas of Korea, during summer months (June, September)
  • Influenza, recommended year-round given Korea's temperate climate and indoor social culture
  • COVID-19, not required for entry but recommended to be up to date on current boosters per your home country's guidelines
  • Routine vaccinations, ensure measles-mumps-rubella (MMR), diphtheria-tetanus-pertussis, and varicella are current

Health Insurance

South Korea does not require travelers to carry health insurance as a condition of entry. But it is strongly recommended. Medical care in South Korea is of high quality but costs can be substantial for uninsured foreign visitors. Emergency room visits, hospitalization, and specialist consultations are significantly more expensive without the National Health Insurance system that covers Korean residents. Purchase complete travel insurance that includes emergency medical evacuation before departure. Some credit cards offer travel medical coverage, verify limits and exclusions before relying on them.

Current Health Requirements: As of early 2026, South Korea has no COVID-19-related entry requirements, no vaccination proof, testing, or quarantine is required for international arrivals. Requirements can be reimposed during outbreaks of novel respiratory illnesses. Travelers should check the Korea Disease Control and Prevention Agency (kdca.go.kr) and their home government's travel advisory within 72 hours of departure for any last-minute health requirement changes.

Special Situations

Additional requirements for specific circumstances.

Traveling with Children

Children traveling with both parents require no additional documentation beyond their own valid passport. Children traveling with one parent should carry a notarized letter of consent from the absent parent, translated into English or Korean, authorizing the child's travel to South Korea, while not always checked, immigration officers may request this for solo-parent entries. Children traveling with neither parent (e.g., with grandparents or on school trips) require a notarized authorization letter from both parents or legal guardians plus the guardian's identification. Child passports must be valid; South Korea does not accept children listed on a parent's passport for entry.

Traveling with Pets

Importing pets into South Korea requires advance planning and can be complex. Dogs and cats must have a microchip (ISO standard 15-digit), a valid rabies vaccination (administered at least 30 days before arrival and within the last 12 months), and a health certificate issued by an accredited veterinarian within 10 days of travel. Pets from non-rabies-free countries (including most of the world) are subject to a quarantine period of 10 days at the Animal and Plant Quarantine Agency facility at Jeju airport, at the owner's expense. Pets from designated rabies-free countries (e.g., Australia, New Zealand, Japan, Taiwan, Hawaii) are exempt from quarantine with correct documentation. Contact the Korea Animal and Plant Quarantine Agency (qia.go.kr) at least 2 months before travel to verify current requirements for your pet's country of origin.

Extended Stays Beyond Tourist Allowance

The Jeju 30-day waiver and standard 90-day visa-free entry cannot be extended by leaving and re-entering Korea (visa runs are not accepted). Travelers wishing to stay longer than their permitted period must obtain an appropriate long-term visa before traveling. Options include: D-2 (student), E-series (employment), F-series (family), or D-10 (job-seeking for certain graduates). Apply through the Korean embassy in your home country. Overstaying your permitted period, even by one day, results in a fine, deportation, and a ban on re-entry to South Korea (typically 1, 5 years). There are no grace periods. If you have a compelling reason to remain beyond your permitted stay (medical emergency, natural disaster), contact the Korea Immigration Service at 1345 before your stay expires.

Travelers with Criminal Records

South Korea may deny entry to travelers with certain criminal convictions, those involving drug offenses, violence, or fraud. There is no formal pre-clearance system (unlike some countries), the entry decision is made by immigration officers at the border. Travelers who have been previously deported from or denied entry into South Korea are likely to face scrutiny. If you have a criminal record and are uncertain about your admissibility, consult a Korean immigration attorney or contact the Korean embassy in your home country for guidance before booking travel.

Media, Journalists, and Content Creators

Journalists and media professionals visiting Jeju for reporting purposes should enter on a tourist visa if conducting casual travel journalism or social media content creation related to activities like jeju beaches, jeju food, and jeju hotels coverage. Formal news gathering requiring press credentials or official interviews may require a C-1 (short-term) visa with a letter from a media organization. South Korea has no formal pre-accreditation system for tourist-category journalism. But carrying press credentials may invite additional immigration scrutiny. When in doubt, contact the Korean embassy or Korea Tourism Organization's media relations team in advance.

Frequently Asked Questions

Does Jeju Island require a visa?

Jeju Island operates a special visa-free zone, meaning nationals of most countries — over 100 in total — can enter without a visa for stays of up to 30 days for tourism purposes. This exemption applies specifically to Jeju and is separate from South Korea's general visa policy, so even nationalities that would normally need a Korean visa can often enter Jeju visa-free. However, a small number of nationalities are excluded from this arrangement and must obtain a standard South Korean C-3 tourist visa before travelling. Always confirm your eligibility on the Korea Immigration Service website (www.immigration.go.kr) before booking flights.

What are the entry requirements for Jeju Island?

To enter Jeju Island, you need a valid passport with at least six months of remaining validity, a confirmed return or onward ticket, and proof of sufficient funds for your stay — though proof of funds is rarely checked for short trips. Most visitors arriving for tourism who qualify for the Jeju visa-free zone simply clear immigration at Jeju International Airport with no prior paperwork. If your nationality is excluded from the visa-free arrangement, you must apply for a South Korean C-3 tourist visa at a Korean embassy or consulate before departure.

What documents do I need to enter Jeju Island?

The minimum documents required are a valid passport (6+ months validity), a return or onward flight ticket, and — if applicable — a South Korean tourist visa. If you are entering under the Jeju visa-free exemption, no advance visa application is needed; the exemption is granted at the border. It is a good idea to carry your accommodation details and travel itinerary, as immigration officers occasionally ask, particularly for first-time visitors.

How does immigration work when arriving in Jeju?

Immigration at Jeju International Airport follows the same process as any South Korean entry point: you join the arrivals queue, present your passport, have your fingerprints and photo taken (first-time visitors and most foreign nationals), and receive an entry stamp. The process is typically smooth and fast — expect 10–30 minutes depending on flight loads. There is no separate immigration line for the Jeju visa-free zone; the exemption is automatically applied based on your nationality.

How does Jeju immigration differ from mainland South Korea?

The key difference is Jeju's standalone visa-free policy: nationalities that require a visa to enter mainland South Korea can often enter Jeju without one, for up to 30 days. However, this exemption is island-specific — if you plan to travel onward to Seoul or anywhere on the mainland, you will need a valid South Korean visa for that leg of the trip. The physical immigration procedures (biometrics, passport control) are identical to those at Incheon or Gimpo airports.

Do Indian passport holders need a visa for Jeju Island?

Indian nationals are currently not included in Jeju Island's visa-free exemption list, which means they must obtain a standard South Korean C-3 tourist visa before travelling to Jeju. Applications are made through the nearest South Korean embassy or consulate in India (Seoul processes them quickly, typically within 5–7 business days for a single-entry visa). The situation can change, so always verify the current rules on the Korea Immigration Service website or with the Embassy of the Republic of Korea in New Delhi before making bookings.

How long can I stay in Jeju on the visa-free exemption?

Eligible visitors under Jeju's special visa-free zone are permitted to stay for up to 30 days per visit, for tourism purposes only. Extensions are not granted under the visa-free arrangement — if you wish to stay longer or for non-tourist activities, you would need to apply for the appropriate South Korean visa. Note that the 30-day limit is strictly enforced; overstaying results in fines, deportation, and potential future entry bans.

Which nationalities cannot enter Jeju visa-free?

While the Jeju visa-free list covers the majority of nationalities, certain countries are excluded — these have included India, China (with some exceptions for group tours via specific channels), and a number of others designated by Korean immigration authorities. Chinese nationals have had a more complex arrangement involving approved group tour packages, so it is worth checking the latest rules specifically if you hold a Chinese passport. The full exclusion list is maintained by the Korea Immigration Service and is updated periodically.

Can I travel to mainland South Korea from Jeju without a visa?

Not automatically. If your nationality already has a general visa-free agreement with South Korea (for example, most EU, UK, US, Australian, and Japanese passport holders), you can travel freely between Jeju and the mainland. However, if you entered Jeju under the island-specific visa-free exemption but your country does not have a broader Korean visa-free agreement, you will need a South Korean visa to travel to Seoul or elsewhere on the mainland. Plan accordingly if your itinerary includes both Jeju and mainland South Korea.

Is travel insurance required to enter Jeju Island?

Travel insurance is not a legal entry requirement for Jeju Island or South Korea more broadly — you will not be turned away at immigration for lacking it. That said, South Korea has excellent but expensive private healthcare, and a single hospital visit can easily cost ₩200,000–₩500,000 (roughly USD 150–375) or more without coverage. Given Jeju's outdoor activities — hiking Hallasan, water sports, cliff trails — comprehensive travel insurance with medical evacuation cover is strongly recommended.

Can I enter Jeju by sea, and do different entry rules apply?

Yes, Jeju is accessible by ferry from several mainland South Korean ports including Mokpo and Wando, and previously from some Chinese ports (check current schedules, as sea routes change seasonally). Immigration and customs are handled at Jeju Port using the same rules as air entry — the visa-free exemption applies regardless of whether you arrive by plane or ferry. If arriving from China by sea, confirm current route availability and any specific immigration requirements with the ferry operator before travelling.
