Most short-stay visitors from the EU, UK, US, Canada, Australia and many other visa-waiver countries may enter South Korea visa-free for up to 90 days, but eligible travellers generally need a valid K-ETA (approx. USD 8 / KRW 10,000, valid 2 years) approved before boarding unless their nationality is under a current exemption. Nationals without a waiver need a C-3 short-term visit visa (consular fee roughly USD 40, apply 4-6 weeks ahead). Carry an invitation letter or exhibitor confirmation for business travel and verify your own status on the official portals (visa.go.kr / k-eta.go.kr) before booking.
Estimated cost: Varies by visa type and nationality (check official site).
Processing: Varies by nationality; apply several weeks before travel.
Fee KRW 10,000 (~USD 8), valid 2 years for multiple entries. Exemptions have been applied to some nationalities on a rolling basis - check the official portal for your passport before booking. Single-entry consular fee is approximately USD 40 and varies by country and reciprocity. An invitation letter or exhibitor confirmation from the organiser materially helps a business-purpose application.
