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 two teams: the International Affairs Team, and Global One-Stop Service Center (GOSC).

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.

Global One-Stop Service Center is in charge of supporting the international community at Yonsei University, by providing various services from visa guidance to transition to a new environment.
