Should multiple nationalities with both foreign and Korean passports also K-ETA application?

If you hold Korean nationality, you cannot exercise foreign nationality in Korea, so you will be screened with a Korean passport when entering or leaving Korea

Therefore, multiple nationalities must present their Korean passports at the time of immigration, and K-ETA application is also not required

However, you must submit both passports to issue a flight ticket

At this time, if the personal information on the passport is inconsistent, boarding may be denied due to K-ETA misrepresentation

In this case, please contact your airline
