A sample of 141 international students from different U.S. colleges completed surveys related to social support, demographic variables, and acculturative stress. Findings indicated that social support and English proficiency uniquely contribute to the variance in students' acculturative stress. Results also indicated that students who primarily socialized with non-Americans and that students from Asian countries experienced more acculturative stress compared with other subgroups, implications are discussed and suggestions for counseling practice are provided.
