This study addressed the challenges encountered by Iraqi graduate students at both the Intensive English Program (IEP) and the regular academic degree programs at U.S. Universities. Using a case study approach, the study focused on five Iraqi graduate students studying at the University of Cincinnati to address those challenges and seek solutions that help both current and future students adjust to an American college campus culture. Two questions guided the research: 1) How do Iraqi graduate students perceive their challenges in a new setting with English as the medium of instruction for the first time, and 2) what social, psychological, and linguistic factors are behind those challenges. Study results revealed the linguistic, social and psychological challenges as experienced by the participants. This study is significant as it describes the types of challenges encountered by the students and offers recommendations to improve the practices of the intensive English programs and better meet students' needs.
