This study examined parental and professor attachment as buffers against acculturative stress and as predictors of college adjustment of 210 Asian international students (AISs). Moderated hierarchical regression analyses revealed that acculturative stress negatively and secure parental and professor attachment positively predicted academic integration. Secure professor attachment positively predicted grade point average. Mother attachment may buffer against acculturative stress on academic integration; father attachment may exacerbate it. Counselors may use these findings to enhance AISs' attachment functioning for their college adjustment.
