Undergraduate Muslim international students in American universities continue to grow in large numbers, however, this population of students face several challenges related to their racial/ethnic, religious, and gender identities. These challenges tend to influence their academic and social experiences and, ultimately, their overall integration on campus. Yet, much of the research has not focused specifically on this population of students even though their experiences are unique and worthy of exploration. Therefore, the purpose of this qualitative phenomenological study was to understand and describe the lived experiences of degree-seeking undergraduate Muslim international students on American campuses. Specifically, the study explored the racial/ethnic, religious, and gender experiences of this population, as well as the influence of those experiences on their academic and social integration. This phenomenological study included semi-structured interviews with eight students who attended four-year public national universities in the Western region of the US. The concept of Islamophobia and the Campus Climate Framework were employed to uncover how this population of students experience and perceive their campuses. Eight themes emerged from this research study and represented the undergraduate Muslim international students' experiences. First, students' faced classroom challenges related to linguistic abilities and other's perceptions of their academic performance based on their racial identity. They reported that the expression of their Muslim identity through the hijab and the thobe result in exclusion and feelings of resistance. These students encountered microaggressions, overt prejudice on campus, and hostility off campus due to their racial and religious identity. The national political climate also caused feelings of intimidation, marginalization, fear, and discrimination. Although students received institutional, faculty, and individual support, as well as perceived the Muslim Student Association as a strong support system, they advocated the need for religious and cultural integration.
