Based on Berry's seminal work on the acculturation process, this study examines the pattern of acculturation attitude among international postgraduate students in Malaysia, an emerging education hub in Asia. It also investigates the influence of several demographic factors (gender, geographical region, marital status, and education level) and predictors (English language proficiency, media usage, intention to stay in the host country after graduation, and perceived positive stereotype image) on international postgraduate students' four acculturation attitudes "integration", "separation", "assimilation", and "marginalization". Our survey of a sample of 1,186 international postgraduate students reveals that the most prevalent acculturation attitude chosen by the international postgraduate students is integration. The identified predictors are shown to positively influence integration attitude while the demographic factors have no significant effect on international postgraduate students' acculturation attitude in Malaysia. Study findings provide valuable insights for education policymakers and university administrators to manage and address the needs of international students via effective acculturation programs.
