This qualitative study examines the experiences of undergraduate, foreign-born immigrant women pursuing STEM careers. Eighteen students from two different institutions were interviewed. Employing a science identity framework, we explored how internal and external recognition influenced women’s identities as future STEM professionals. Data were analyzed using constructivist grounded theory approaches. Results include three main categories: identifying positive sources of external recognition and support, encountering discriminatory classroom environments, and incorporating altruistic and familial goals. We synthesized our findings in an emerging grounded theory model of science identity development for foreign-born immigrant women in undergraduate STEM programs. This model leads to several implications for how student affairs professionals can support immigrant women in STEM.
