This chapter is a review of the literature concerning the individual factors that help international students thrive in their ‘host' countries. Convergent findings indicate that being independent, participating in extra-curricular activities, having self-efficacy, cultural empathy, maintaining relations, and being open-minded are the most significant individual factors related to the adjustment of international students. However, in this study on Asian Indian international students, four unexplored factors, namely, being polite, professionalism, showing gratitude, and thinking positively, were also found crucial in cross-cultural adjustment. Such a finding warrants identification of hypothetical connections that are informative, but empirically unexplored. Based on a synthesis of current literature, the author presents the novel hypothesis that being polite, professional, showing gratitude, and thinking positively all facilitate the general international student population to thrive in the host countries. The objective of this review is to provide relevant resource material to international student counselors and university administrators to help international students succeed during their time abroad.
