South Korea to Thailand visa requirements

Visa-free up to 90 days for Korean ordinary passports under the Korea-Thailand bilateral agreement. TDAC is required before arrival. Official Thai sources list South Korea in both Thailand's 60-day general visa-exemption list and the separate 90-day bilateral ordinary-passport agreement. The Korea-specific Royal Thai Embassy Seoul tourist-visa notice updated on 16 June 2026 and Korea MOFA's visa-exemption table both state that Korean ordinary passport holders may visit Thailand visa-free for up to 90 days. Treat 90 days as the current ordinary-passport visitor ceiling, check the stamp issued at entry, and use the correct visa or Thai Immigration approval for work, study, or any stay beyond the permitted stamp. All non-Thai nationals must submit the Thailand Digital Arrival Card (TDAC) online before entry, no more than 3 days before arrival.
