This study focuses on 15 foreign-born students majoring in physics who are also racial/ethnic minorities. We address the research question: What are the acculturation experiences of foreign-born Students of Color majoring in physics? Berry's (2003) theory of acculturation and Bandura's (1994) theory of self-efficacy were substantive frameworks for analyzing the data. The findings illustrate participants' cultural, educational, and social adjustments. Emphasis is placed on how participants navigate and achieve success in this process.
