Using data from a 2-year qualitative study, the author examines how East African Muslim immigrant youth experience and become shaped by the environments of U.S. mainstream schools compared with a culturally specific charter high school. Results from this study reveal that East African Muslim immigrant youth are affected by religious and cultural discrimination in mainstream schools and that attending a culturally specific charter school promotes positive intercultural competence in which students are able to build a good self-concept and find comfort in who they are as East African immigrants, as Muslims, and as American citizens.
