Culture and heritage language (HL) preservation are crucial to developing children of immigrants’ ethnic and social identity, creating a sense of belonging, and fostering family and ethnic community support. However, numerous challenges permeate the experiences of underrepresented ethnolinguistic groups like Brazilian immigrants who are largely invisible in the United States. Therefore, this study investigated the lived experiences of second-generation Brazilian adolescents with culture and HL preservation. In-depth interviews and a focus group were conducted with 13 participants. The findings highlighted the participants’ embrace of their Brazilian ethnic identity and rejection of their American citizenship, and emphasized HL in affirming their identities and confronting discrimination.
