Most short-stay business visitors from the United States, European Union, United Kingdom, Australia and Canada enter South Korea without a visa for meetings and trade-fair attendance of up to 90 days, but visa-waiver nationals must hold an approved K-ETA (Korea Electronic Travel Authorization) before boarding — apply at k-eta.go.kr at least two weeks ahead. Nationals without a waiver agreement, including much of South and Southeast Asia, Africa and the Middle East, need a C-3 short-term business visa issued by a Korean embassy or consulate in 5–10 working days. Carry the KPEX invitation from the organiser, a return ticket and proof of accommodation; all visitors should hold six months' passport validity.
Estimated cost: Varies by visa type and nationality (check official site).
Processing: Varies by nationality; apply several weeks before travel.
Apply only through the official k-eta.go.kr portal; authorisation is valid for two years with multiple entries and is verified by the airline at boarding. Requires the KPEX invitation letter, company registration documents and proof of accommodation; single-entry validity is up to 90 days.
