“No more Korean at Home.” Family language policies, language practices, and challenges in Korean immigrant families: Intragroup diversities and intergenerational impacts

•This study explores the cases of Korean immigrant families who have different transnational life trajectories. Despite the fast-growing research interests in family language policy, the intragroup diversity of Korean immigrant families and their daily interactions are not yet widely discussed. The goal of this study is to explore intergenerational impacts and intragroup diversities among Korean immigrants. Throughout two years, I conducted several interviews with the families of the 1st generation, consisting of short-term stayers and long-term stayers, and 1.5 generation. I collected language profiles and background questionnaires in addition to family interactions over the dinner table.•Though the field of FLP research has been gaining attention, it still lacks in many aspects. FLP is an important area where much remains to be explored in terms of the different types of families, diverse languages, and distinct research methodologies. In addition, despite Korean transnational families’ various implementations of FLP to promote family's bilingualism, not many empirical studies examine intragroup diversity among the same ethnic group and their diverse language practices. To attempt to fill this gap, the current study will explore intragroup diversity among Korean transnational families residing in the same geographical region, who have different immigrant backgrounds, future orientations, and motives for pursuing bilingualism. It also captures the context-specific nature of family language policy, and the complex relations between parental language ideologies and the actual implementation of their FLP in language practices in each group. The findings show the parents’ educational and linguistic choices for their children are based on the family's socio-cultural background, attitudes towards bilingualism, and future orientation. This study reinforces the understanding of how multiple linkages in transnational experiences are orchestrated, and how they may or may not conflict with immigrant families’ language practices.•This study reinforces our understanding of how the multiple linkages between transnational life experiences and language ideologies are orchestrated, whether it is in harmony or in conflict, with immigrant families’ language practices. This study also contributes to the existing FLP field by extending the scope of FLP research to not only “what” the particular family's FLP is, but also “how” they construct their FLP in daily interactions.
