Data Accuracy at Immigration: how it works in South Korea — first-hand

For travelers arriving on separate flights, it is not strictly necessary to list companions in the K-ETA, but be prepared to provide the companion's name and flight details to immigration officers at the border if questioned.

If your travel plans change after obtaining K-ETA, you must update the information, including travel dates, accommodation details (hotel name), and companions. If you are traveling on a D-2 visa, any existing K-ETA should be canceled. It's crucial that the information provided in your K-ETA application accurately reflects your travel purpose (e.g., tourism vs. visiting friends). Upon arrival, be prepared to show proof of funds (approximately $100 USD per day in cash), return tickets, and a confirmed accommodation booking. Having a planned itinerary can also be beneficial.

When filling out the K-ETA, ensure the information provided aligns with your actual travel plans. While the previous 10-day pre-travel update requirement for K-ETA has been removed, it's still advisable to review and save your application details, especially if your travel dates, accommodation, or return flight information changes. Accuracy in the K-ETA application is crucial, as discrepancies upon arrival (e.g., stating 'tourism' but intending to visit friends) can lead to entry refusal.

Only specific entry details (accommodation, flight, dates of stay) need to be updated. Consistency between K-ETA information and actual documents (hotel bookings, flight tickets) presented to the immigration officer is critical for entry.

Discrepancies between declared and actual income can lead to issues at customs and potentially a denial of entry. It's best to provide accurate information.
