Common Entry Types

Visa exemption (K-ETA currently suspended)
As a U.S. citizen, you can enter South Korea visa-free for tourism or short-term business, for up to 90 days. South Korea normally requires K-ETA (a pre-travel authorization) for visa-exempt visitors, but that requirement is temporarily suspended for U.S. citizens through December 31, 2026. You still need to complete the free e-Arrival Card online within 72 hours of arrival, even while K-ETA itself is suspended.

Overstay Consequences

  • Overstaying is an offense that can lead to fines, and in more serious or repeated cases, detention and deportation.
  • An overstay record can affect eligibility for future entry, including future K-ETA approval once that requirement resumes.

Renewal Path

  1. 1Extensions of a short-term visa-exempt stay are handled by the Korea Immigration Service and are not routine — approval depends on your circumstances and generally requires applying before your permitted stay expires.
  2. 2K-ETA becomes mandatory again on January 1, 2027, at which point airlines will enforce it at check-in — a fresh application will be required for any trip after that date.

The Gotcha

Right now, U.S. citizens don't need K-ETA to visit South Korea — but that's a temporary suspension, not a permanent policy change, and it's currently scheduled to end December 31, 2026. If you're planning a trip for early 2027, don't assume the current 'no K-ETA needed' status still applies — check k-eta.go.kr before you travel.
