Objective: To identify stressors affecting international students' mental health during the COVID-19 pandemic. Participants: Twenty-two international students from 10 countries and 17 US institutions participated. Methods: Participants were recruited from a larger study examining the wellbeing of young adults during the pandemic. Results: Four main stressors were identified: (1) Uncertainty and anxiety induced by decisions and policies in response to COVID-19; (2) Fears regarding xenophobia; (3) Limited understanding by educators and school staff of international students' unique challenges; (4) Greater awareness of racial and cultural identity. Conclusion: The pandemic has contributed to additional stressors for international students. Educators and mental health professionals may help support international students' mental health by gaining basic knowledge about common stressors and directly acknowledging the challenges, educating international students on race and racism and supporting anti-racism efforts, and encouraging the creation of shared affinity spaces and increasing psychoeducation to promote resilience.
