A large body of work has demonstrated the substantial intergenerational mobility experienced by children of immigrants, yet the institutional determinants of incorporation are poorly understood. Building on insights from neo-classical assimilation theory, this article analyzes in-depth interviews with 62 high-achieving children of labor immigrants from Pakistan, Turkey, India, and Morocco and investigates how they maneuvered through Norway’s educational system and reached their current positions as medical doctors, lawyers, and business professionals. We show that these children of immigrants from low-income households capitalized on a series of institutional opportunity structures provided by Norway’s egalitarian welfare state, such as a school system with high standardization and low stratification, free higher education, and a cultural and institutional context that supports women’s employment. In line with neo-classical assimilation theory, we argue that the specific institutional structures and cultural beliefs in the Norwegian context shape the strategies and forms of adaptation chosen by ethnic minority groups. However, our analyses suggest the need for careful consideration of how such strategies and adaptations vary across national contexts.
