South Korean passport holders enter Thailand visa-free for up to 60 days (extended from 30 days in 2024). No fee, no advance application. Passport must be valid for at least 6 months beyond the date of entry. You need a return or onward ticket and proof of funds (THB 20,000 per person or THB 40,000 per family, though this is rarely checked in practice).
The 60-day visa-free stay can be extended once for 30 additional days at any Thai Immigration office for THB 1,900 (about $55). The Chaeng Wattana office in Bangkok and offices in Chiang Mai and Phuket handle extensions in 1 to 3 hours. For longer stays, a 60-day tourist visa from the Royal Thai Embassy in Seoul costs KRW 40,000 and is extendable for another 30 days in Thailand. Multiple-entry tourist visas (METV) cost KRW 200,000 and allow 60-day entries for 6 months.
