International graduate students have been a sizeable segment of the student body in the U.S. higher educational system. However, this student population has not completely been understood by higher education administrators and faculty and their diverse needs have not been met by existing services on campuses. This study examined factors associated with the students' academic performance in the United States. The findings indicated that factors associated with masters and doctoral students' academic performances were greatly different. This study suggests policies, services and programs to meet this population's unique needs and to assist in their academic success in the United States.
