The COVID-19 pandemic has exerted a profound impact on numerous facets of our daily lives, including in higher education. International students have encountered unique challenges due to their vulnerability stemming from living abroad, including cultural adjustments, language barriers, and separation from families and friends. This review aims to examine the educational, financial, sociocultural and psychological impacts experienced by international students in the context of the pandemic and identify areas requiring support for this group. A systematic search of eight databases yielded 78 relevant papers for inclusion. Through a systematic qualitative synthesis, this review presents an increased understanding of the multifaceted impact of COVID-19 on international students, encompassing five key themes: 1) unprecedented learning barriers, 2) stalled transnational mobility, 3) heightened financial, social, and cultural challenges, 4) exacerbated racism and racial discrimination, and 5) increased mental health risks. By systematically synthesising the distinctive challenges faced by international students in the context of the pandemic, this review provides recommendations for evidence-based support for international students in the post-pandemic era.
