Overview
Taiwan and South Korea maintain no formal diplomatic relations, so Taiwan's presence in Seoul takes the representative-office form: the Taipei Mission in Korea, on the 6th floor of the Gwanghwamun Building on Sejong-daero, performs the consular and visa functions an embassy otherwise would. For Korean travellers the practical picture is simple — Taiwan grants them 90 days visa-free — which leaves the mission handling long-stay cases, document work, and one of Northeast Asia's busiest informal relationships.
Visa Services
Korean passport holders enter Taiwan visa-free for up to 90 days with a passport valid six months; the online Taiwan Arrival Card (twac.immigration.gov.tw) can be filed from seven days before arrival and speeds the airport queue. The mission's visa section — consular windows weekday mornings 09:00–11:30 and afternoons 13:30–15:30 — handles what the exemption does not: work and study visas, joining-family stays, and applications from third-country nationals in Korea whose passports need a Taiwan visa, coordinated with Taiwan's Bureau of Consular Affairs online systems.
Consular Services
The mission provides passport, document-authentication, and emergency services for Taiwanese nationals in Korea — students, businesspeople, and long-settled residents — with an emergency line for after-hours cases, and a branch office in Busan serving the southeast. Document legalisation between the two jurisdictions runs through the mission's authentication desk.
Trade & Export Support
Taiwan and South Korea are simultaneously competitors and indispensable partners across the semiconductor supply chain, and the trade relationship — machinery, chemicals, electronic components in both directions — ranks among each side's largest. The mission's economic division supports Taiwanese businesses in Korea alongside TAITRA's Seoul office.
Investment Opportunities
Cross-investment concentrates in technology: Taiwanese component and materials firms hold Korean positions, while Korean electronics and battery players source deeply from Taiwan's ecosystem. The mission's economic division is the first policy-level contact for Taiwanese investors in Korea.
Business Support
Taiwanese companies operating in Korea route practical support through TAITRA Seoul and the mission's economic division; Korean firms exploring Taiwan work the mirror path through Seoul's own representative channels in Taipei — the informal structure changes the letterhead, not the volume of business.
Cultural & Educational Programs
People-to-people traffic is the relationship's loudest channel: direct flights link Seoul and Busan with Taipei and Kaohsiung year-round, Taiwanese food and travel content saturates Korean social media, and Mandarin-language study sends Korean students to Taiwan's universities. The mission's cultural division runs Taiwan-culture programming and study-in-Taiwan fairs in Korea.
Appointment Information
Tourists need no contact with the mission — the 90-day exemption plus an optional pre-filed Taiwan Arrival Card covers the trip. Visa and consular matters: Taipei Mission in Korea, 6th Floor, Gwanghwamun Building, 149 Sejong-daero, Jongno-gu, Seoul 03186; phone +82 2 6329 6000 (consular menu option 1); windows weekdays 09:00–11:30 and 13:30–15:30; forms and requirements at roc-taiwan.org/kr_ko.
Special Notes
The Taiwan Arrival Card is free at twac.immigration.gov.tw and can only be filed within seven days of arrival — earlier submissions are not accepted, so calendar it into the final packing week. The 90-day window cannot be extended for tourism; long stays need the right visa before travel. The mission is a representative office, not an embassy — its consular powers cover the practical needs travellers and residents actually have.
