This dissertation research investigates the experiences of international student-athletes competing in NCAA Division I schools in the Southeastern United States. The study explores the challenges and successes these athletes encounter as they navigate academic and athletic pursuits in a new environment. The purpose of this dissertation research study was to research the experiences of international student-athletes competing in NCAA Division 1 schools across the Southeastern United States. A particular focus is placed on the impact of varying English language proficiency on their academic experiences, as well as the broader influence of language and cultural differences on their overall integration. The unique cultural and historical context of the Southeast, with its complex history and potential for social tensions, may present additional challenges for international student-athletes. By examining how these factors affect athletic performance, social participation, and cultural acclimation, the study aims to inform college and university leaders and coaches on how to better support the well-being and success of international student-athletes within the NCAA Division I system. The research posed two questions. First, how did international student-athletes acclimate to their schooling and athletics at NCAA Division I schools in the Southeastern United States? Second, what are the lived experiences of international student-athletes at NCAA Division I universities in the Southeastern United States, as shaped by the interplay of language, cultural background, and the demands of academic, athletic, and social life? The research questions address how international student-athletes acclimate to schooling and athletics and what their lived experiences are shaped by the interplay of language, cultural background, and academic, athletic, and social life. The findings and qualitative data suggest international student-athletes face heightened challenges, potentially hindering their acclimation process. Findings emphasize the need for a holistic support ecosystem addressing English proficiency, cultural needs, financial constraints, and overall well-being. Recommendations include culturally competent support services, financial aid programs, and opportunities for social integration. By fostering a more welcoming environment, institutions can empower international students to thrive academically, culturally, and personally.
