The Office of International Affairs (OIA) provides strategic direction for Yonsei University’s global endeavors in its mission to become Asia’s World University.

Since its establishment in 1966 as the first international office among Korean universities, the OIA has developed significant partnerships with leading universities around the world to develop collaborative global strategies, initiatives, and programs and ensure a culturally rich environment for students and faculty on campus. The office consists of three teams: the International Affairs Team, International Student and Scholar Support Team, and International Admissions Team.

The International Affairs Team is in charge of international partnerships, exchange programs, international visits and protocol, and non-degree programs including Yonsei's international Summer and Winter Schools.

The International Student and Scholar Support Team provides international faculty support and is in charge of government scholarships for international degree-seeking students.

The International Admissions Team oversees international students' admission to the undergraudate degree program.
