Life as an ethnic minority (EM) university student: Comparing mental health challenges among local and international EM students in Hong Kong

open access: yesBritish Educational Research Journal, EarlyView.
Abstract University students globally face growing mental health challenges, with ethnic minority (EM) students—both local and international—being particularly vulnerable. Yet, limited research compares their experiences or identifies shared and distinct stressors, especially in non‐Western contexts.
