Taipei Mission in Seoul

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.

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.

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.

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.

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.

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.

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.

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.

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.
