This exploratory study investigates the transnational identity formation of second-generation Iranian young adults living in Montreal. Within a conceptual framework emphasizing the relational nature of identity formation, the article seeks to shed light on the multifaceted impact of dynamics within and outside the family institution on my respondents’ identity construction. From the dozen of interviews conducted so far, I have outlined the effects of the family’s internal dynamics, the transnational networks developed by my informants, as well as the multiple effects of the local socio-political environment, on the latter’s identity formation process.
