Incheon Airport and Immigration: how it works in South Korea — first-hand

Requirements may include proof of accommodation, return tickets, and length of stay. While the process is generally smooth and efficient, having necessary documents ready is advisable. Some travelers may be asked for additional information or documentation based on their profile (e.g., age, employment status, nationality). An arrival card may be required, but is not always. Be calm and cooperative during the process.

An immigration officer meticulously examined their passport, questioning details like the birthplace designation (province vs. region). While some travelers pass quickly, others, like the user's husband, faced significant delays and scrutiny. Confiscation of items like lighters and yogurt was also mentioned. Lack of a smoking lounge in the transit area was noted as inconvenient.

If communication is required, the Papago translation app is highly recommended over Google Translate. Papago is widely used in Korea, supports voice, photo, and text translation, and is generally more effective for Korean language interactions.

Completing the Arrival Card online beforehand can streamline the process. Having your itinerary readily available in your backpack is recommended. Generally, the procedure is efficient, even with significant queues.

K-ETA is accepted, fingerprints are taken, and a QR code is placed in the passport. No unusual questions were asked regarding finances.

Be prepared for questions about return tickets. Some travelers may pass without issues, while others might be interrogated.
