A mixed-methodology approach was employed to gain a better understanding of international graduate students' perceptions of academic and social isolation, both in traditional and online environments, to see if these differ, and to explore suggestions for improving their sense of engagement within their learning communities. A survey was completed by 54 respondents and ten individuals participated in focus group sessions or individual interviews. The results show that international students, both in traditional and online programs, experience/perceive high levels of isolation, academically and socially. However, online international students may feel even more isolated than their traditional counterparts. The independent variables gender, type of degree, and family presence appear to also have some influence on some of the respondents' answers. Participants suggested several types of potential interventions they would find useful.
