This study examines the dynamics of interpersonal communication among migrant students at Raden Wijaya State Buddhist College in their social and academic lives in Wonogiri Central Java. Migrating for higher education places students in a simultaneous adaptation process involving language, culture, and academic demands. This qualitative study used a case study method and involved six migrant student informants from the 2025 cohort who were selected purposively based on regional background variation. Data were collected through semi-structured interviews, direct observation, and documentation, then analyzed using the interactive model of Miles and Huberman. The results of the study show that interpersonal communication goes through a gradual adaptation process. In the early stage, language differences and communication norms encouraged students to stay close to their home-background peers, later, Indonesian became the main medium for cross-cultural relations. In the academic setting, communication with lecturers remained formal and cautious, while peer group discussion became the most effective strategy for overcoming comprehension barriers. These findings show that interpersonal communication functions as a foundation for social adaptation, emotional stability, and academic success among migrant students in a multicultural campus environment.
