01 1. [Key Takeaways] Korea Entry & Stay Declaration Matrix at a Glance
All travelers entering South Korea must fulfill specific pre-departure digital declarations or in-flight paper forms depending on their citizenship, stay duration, and visa type.
Short-term visitors (<90 days for tourism/business) require Q-CODE health clearance, an approved K-ETA (or paper Arrival Card if not holding K-ETA), and a Mobile Customs QR code only if exceeding the $800 USD duty-free allowance.
Long-term foreign residents (>90 days for study, work, or residency) are legally mandated to register for an Alien Registration Card (ARC / Residence Card) within 90 days of arrival and report any change of address within 14 days to avoid severe fines up to ₩3,000,000 KRW.

02 2. Short-Term Travelers (<90 Days): The 3 Pre-Entry & Arrival Steps
1. Q-CODE (Quarantine Information Pre-Entry System): Visit qcode.kdca.go.kr 48 hours before boarding. Input your passport info, flight number, stay address, and health status (fever, cough). Save the generated QR code to your phone photo gallery to scan through quarantine gates in under 3 seconds upon landing.
2. Arrival Card (입국신고서): Foreigners with an approved K-ETA or registered ARC holders are EXEMPT from filling out paper arrival cards. Visa-waiver tourists from the 22 K-ETA-exempt countries who choose not to apply for K-ETA must fill out the yellow paper Arrival Card distributed by cabin attendants during the flight.
3. Customs Declaration (여행자 세관신고): In South Korea, travelers with 'Nothing to Declare' (goods under $800 USD, up to 2 bottles of alcohol under 2L total, 200 cigarettes, and 100ml perfume) do NOT need to write any paper or mobile form; simply walk through the Green Channel. If carrying excess items, scan your Mobile Customs App QR code at the automated tax gate.

03 3. Long-Term Residents (>90 Days): Essential Immigration Post-Arrival Protocol
