International student mobility is an important issue in many countries. In 2016, the number of international students reached 5 million worldwide. Turkey has attracted international students since the 1990s; however, the influx of such students has increased notably since 2009. In this study, we analyze factors affecting the social adjustment of international students studying at Usak University in Turkey. Participants' questionnaire responses were grouped via factor analysis, and pertinent factors affecting social adjustment were revealed through logistic regression analysis. Results indicate that feeling safe and communicating with counseling services and university lecturers can facilitate international students' social adjustment at Usak University.
