Practical tips for a smooth, safe, and enjoyable conference experience!

Attending the World Conference on Lung Cancer (WCLC) 2026 in Seoul is both exciting and enriching. Proper planning — especially when travelling with health, energy, or mobility in mind — helps ensure a smooth and comfortable experience.

Key Conference Details:

• Conference Dates: September 12 – 15, 2026

• Venue: COEX Convention & Exhibition Center, Gangnam-gu, Seoul

Below is a practical guide to help you prepare for your trip.

Step 1: Understand Korea’s Entry Requirements (Visa, K-ETA, e-Arrival Card)

South Korea has recently updated its entry process. Even if your nationality is visa-exempt, you likely still need to complete a digital step before you travel. Please review the three possible requirements below.

1. Check if you need a Visa A visa is formal permission to enter Korea for a specific purpose (e.g., conference attendance).

• Who needs it? Travelers from countries that do not have a visa-waiver agreement with Korea.

• How to check: Visit the official website of the Korea Immigration Service : https://www.immigration.go.kr/immigration_eng/index.do or your local Korean embassy/consulate.

• How to apply: Apply well in advance through your local Korean embassy or consulate. Required documents typically include your passport, a completed application form, a conference invitation letter, travel itinerary, proof of funds, and a visa fee.

2. Check if you need K-ETA (Korea Electronic Travel Authorization)

The K-ETA is an electronic travel authorization for travelers from visa-exempt countries. It is not a visa, but it is mandatory for many visa-exempt nationals to obtain approval before boarding a flight or ship to Korea.

• Official Website: https://www.k-eta.go.kr

• When to apply: At least 72 hours before your departure.

• Who needs it? This depends on your nationality. Some visa-exempt countries are temporarily exempt from K-ETA. You must check the official K-ETA website for the most current list. Do not assume you are exempt.

3. Complete the e-Arrival Card (All foreign visitors) The e-Arrival Card is a mandatory online arrival declaration for all foreign visitors (with very few exceptions). It replaces the old paper arrival card.

Official Website:

https://www.e-arrivalcard.go.kr (⚠️ This service is FREE. Beware of fake websites asking for payment.)

When to complete

You can submit it within 3 days before your arrival in Korea.

Who needs it?

All foreign visitors must submit an e-Arrival Card unless you hold a valid, approved K-ETA.

Even if you have a visa or are from a visa-exempt country, you will likely need to submit this form.

Step 2: Visa Application Process (If a visa is required for your nationality)

If your nationality requires a visa to enter South Korea, please follow these guidelines. Check visa requirements early Visa rules vary by nationality.

Check with the Korean embassy or consulate in your country. Some nationalities can enter visa‑free for short stays; others need a visa in advance. Apply at least 6–8 weeks before travel Processing can take 2–4 weeks, sometimes longer during peak seasons. Starting early reduces last‑minute stress.

Prepare required documents (typical list)

• Valid passport (with at least 6 months validity and 2 blank pages).

• Completed visa application form.

• Conference invitation letter from WCLC / IASLC.

• Travel itinerary (flight booking, hotel reservation).

• Proof of funds (recent bank statement, or a sponsor’s letter).

• Travel insurance (covering medical expenses).

• Letter from your organisation (if applicable) confirming your role and purpose of travel.

Submit your application

Attend your visa appointment with hard copies of all documents, neatly organised. Biometrics (fingerprints, photo) are usually required. Keep a copy of the application receipt or tracking number.

Track and collect your visa

Most embassies allow online tracking. Once approved, check that all details on the visa sticker are correct (name, passport number, validity dates).

Travel with both your passport and visa (printed or digital copy) at all times.

Note: For most individuals, the invitation letter you receive from IASLC through the registration process will suffice for your visa application. For a small number of people or countries, you may need an additional requirement to confirm a local host (in Korea). The WCLC meeting endorser, Korean Association for Lung Cancer, will provide this. Please reach out to our conference registration team wclc2026-registration@icsevents.com if you require information from a local host organisation in Korea.

Step 3: Important Travel Guidelines

Passport and immigration

Ensure your passport is valid for at least 6 months beyond your departure date. Upon arrival in Korea, your passport will be stamped. Keep your conference invitation letter and hotel booking handy – immigration officers may ask for proof of purpose of visit.

Travel insurance

Strongly recommended, especially for attendees with ongoing health conditions. Check that your policy covers medical emergencies, hospitalisation, and trip interruption.

Bringing medications into South Korea – Important restrictions

South Korea has strict regulations on importing medications, particularly those that could be classified as controlled substances (e.g., strong painkillers, sedatives, ADHD medications, benzodiazepines).

Before you travel

All travelers, regardless of nationality, must obtain advance approval from the Korean Ministry of Food and Drug Safety (MFDS) before bringing medications that contain controlled substances into the country.

This includes some common prescription drugs. You can apply online through the MFDS website: https://kr.usembassy.gov/services-controlled-substance/ or email narcotics@korea.kr for current information.

For non-controlled medications: You may generally bring up to a three-month supply for personal use. You should carry your original prescriptions and a letter from your doctor (in English or Korean) specifying your medical condition and listing your medications.

Prohibited items: Marijuana, CBD oil, hemp-derivative products, and even food products containing poppy seeds (e.g., certain bagel seasonings) are heavily regulated and should not be brought into Korea without express written approval. Possession can lead to arrest and deportation.

General advice

Keep all medications in your carry-on luggage with original pharmacy labels. When going through customs, if you are uncertain whether a medication is restricted, declare it to the customs officer. The final decision is made by Korean Customs at Incheon Airport.

Health preparations

Carry a list of your medications, dosages, and generic names. Bring enough medication for the full trip (plus a few extra days).

Local SIM / roaming

Consider purchasing a local SIM card or e‑SIM at the airport (e.g., KT, SK Telecom). Free Wi‑Fi is available in most hotels, conference venues, and many public areas.

Local Emergency Numbers (save these in your phone)

• Police: 112

• Ambulance / Fire: 119

Step 4: What to Pack (Travel Essentials)

Travel documents (must always be handy)

• Passport (with visa if required, and K-ETA approval if applicable)

• e-Arrival Card confirmation (digital or printed)

• Conference invitation and registration confirmation

• Flight booking and hotel reservation (printed or digital copies)

• Travel insurance certificate

• Doctor’s letter and prescriptions for medications

• Emergency contact numbers (embassy, conference help desk, hotel)

Money & currency

The local currency is the South Korean Won (KRW). Carry some cash in small denominations for taxis, street food, or small shops. Credit/debit cards (Visa/Mastercard) are widely accepted. Notify your bank before traveling to avoid card blocks.

Electronics & power needs

Plug type: Type F (two round pins) – same as most of Europe. Voltage: 220V – check that your device chargers support it. Recommended: Universal travel adapter + power bank. Most hotels and the conference venue have free Wi‑Fi.

Clothing & weather readiness (Seoul, September)

September is mild to warm during the day, cooler in the evenings. Rain is possible.

• Pack layers – a light jacket or sweater for indoors and evenings.

• Bring comfortable walking shoes – conference halls and subway stations involve a lot of walking.

• One outfit per day + one smart‑casual option for evening events or receptions.

• Use a lightweight suitcase with smooth‑rolling wheels for easier movement.

Health & personal items

• Bring enough medication for the whole trip (plus a few extra days).

• Simple first‑aid items: plasters, pain relief, hand sanitiser, face masks. Any mobility aids you rely on (walking stick, cane, foldable stool).

• Carry a refillable water bottle and small snacks for energy between sessions.

Step 5: Travel & Arrival Tips At the airport (before departure)

Arrive at least 3 hours before your international flight. Keep all travel documents (passport, visa, boarding pass) in an easily accessible place. Upon arrival at Incheon International Airport (ICN) Follow signs to immigration – have your passport and visa/K-ETA (if required) ready.

After baggage claim, you can exchange money, buy a T‑money card, or pick up a local SIM.

Getting from the airport to Seoul

• AREX Express Train – fast (approx. 43 minutes to Seoul Station).

• Airport Limousine Bus – comfortable, stops at major hotels.

• Taxi / ride hail – more expensive but door‑to‑door. Official taxi stands are clearly marked. Getting around Seoul

• Subway – clean, efficient, signs and announcements in English.

• T‑money card – rechargeable card for subway, bus, and even convenience stores. Buy at any subway station or airport convenience store.

• Taxis – use the Kakao T app or official taxi queue.

• Navigation apps: Google Maps works less reliably for walking/driving in Korea. Download Naver Map or Kakao Maps (English version available) before you go.

At the conference venue (COEX, Gangnam)

• Wear your name badge clearly.

• Study the floor plan – locate restrooms, rest areas, water stations, and the first‑aid room.

• Ask for help – conference volunteers and staff are there to assist.

• If you feel tired, dizzy, or unwell: sit down immediately and ask a volunteer to call for medical help.

Step 6: Making the Most of Your Trip

Pacing yourself at the conference

1. You do not need to attend every session. Pick 2–3 sessions per day that matter most to you.

2. Take breaks – step outside or find a quiet corner when you feel tired.

3. Carry a small notebook or use your phone to note down one or two key takeaways each day. That is enough.

Networking & connection

Carry a few business cards or have a digital contact‑sharing method ready (e.g., LinkedIn QR code). Short, genuine conversations are more valuable than collecting many contacts. Do not feel pressured to network for hours – one good conversation is a success.

Food & local culture

Korean food is diverse and widely available. Common dietary needs (vegetarian, halal, gluten‑free) can be accommodated – you may need to ask clearly or use a translation app. Conference venues usually provide coffee/tea breaks and sometimes lunch.

Cultural tips

• Say "An‑nyeong‑ha‑se‑yo" (안녕하세요) for “Hello”.

• Say "Kam‑sa‑ham‑ni‑da" (감사합니다) for “Thank you”.

• Receive items with both hands – a sign of respect. Koreans appreciate small efforts to speak a few words or bow gently. A smile works everywhere.

Staying healthy & energised

Drink water regularly – conference air can be dry. Rest when your body tells you to – there is no award for attending every session.

If you have a pre‑existing condition, wear a medical ID or carry a short health summary in Korean (ask your hotel or a local contact to help translate).

Enjoying Seoul responsibly

Explore local attractions only if you have energy – do not overplan. Keep your passport, visa, and valuables in a hotel safe or a secure hidden pouch.

Always know the location of your embassy and the conference help desk.

Final Words

An international conference can feel overwhelming, but you do not have to do everything. One good conversation. One useful session. One rest when you need it. That is already a successful trip.

With proper planning – from understanding the new entry requirements to packing smart, pacing yourself, and preparing for cultural differences – you will have a safe, stress‑free, and memorable experience in Seoul. See you there 💚
