The Catholic University of Korea (CUK) has clear postgraduate (graduate) application requirements for international students, focusing on eligibility, academic qualifications, language proficiency, and documentation. Applicants must qualify as international students, meaning both the applicant and their parents must be non Korean nationals, or the applicant must have completed all prior education outside Korea. For admission, students applying to a master’s or integrated program must hold (or be expected to obtain) a bachelor’s degree, while doctoral applicants must hold (or be expected to obtain) a master’s degree or equivalent qualifications recognized by law. In addition, applicants must demonstrate language proficiency, meeting at least one requirement such as TOPIK level 3 or above, completion of recognized Korean language programs, or submitting valid English proficiency scores (e.g., TOEFL, IELTS, or TEPS) if applying to English-taught programs. The application process typically involves submitting an online application, academic transcripts, degree certificates (or expected graduation proof), passport copies, and other supporting documents, followed by possible interviews or evaluations before final admission.
