Drawing on Kaplan and Baldauf's framework for language policy and planning, this study was designed to shed light on the English as a medium of instruction (EMI) policy in higher education programs in Vietnam. Three groups of participants, including administrators, teachers, and students, were invited to join the study. The data obtained from questionnaires and semi-structured interviews were analyzed and categorized following Kaplan and Baldauf's framework using major aspects related to access, personnel, curriculum, methods, learning materials, resources, community involvement, and student assessment. The study results highlight a stratum of opinions and comments from those involved in the implementation of EMI policy, as well as the challenges they had to deal with. The study speaks to the literature on EMI policy in developing educational contexts and the nexus between global mandates and local constraints.
