US passport holders enter South Korea visa-free for up to 90 days under the K-ETA (Korea Electronic Travel Authorization) exemption. As of early 2026, the K-ETA requirement is waived for US citizens through December 2025 (check for extensions beyond this date).

At Incheon International Airport (ICN), immigration uses automated gates for repeat visitors or stamps your passport at the counter.
