It explores heritage language maintenance and education in Korean communities, with a focus on perspectives from three different countries.Heritage languages refer to the languages spoken by immigrant communities and their descendants, which are often passed down through generations (Hornberger & Wang, 2008;Ndhlova & Willoughby, 2017;Valdés, 2001). Research around heritage languages investigate a variety of sociolinguistic and educational issues, such as heritage language maintenance and shift, heritage language education, and parental attitudes towards children's language maintenance.Heritage language maintenance refers to the process of preserving and continuing to use the heritage language of one's ancestors or cultural community (Clyne & Kipp, 1996;Pauwels, 2004), while heritage language shift refers to the process of losing the heritage language and adopting the dominant language of the community they reside in (Tran et al., 2022;Zhang et al., 2023). Heritage language maintenance is especially important for immigrant families or communities who may have migrated to a new country where the majority language is different from their heritage language. In many cases, the maintenance of the heritage language helps to maintain cultural or ethnic identity, values, and traditions (Brown, 2011;Escudero et al., 2022). The decision to maintain or shift from heritage languages can have significant implications for the individual and the community, including loss or shift in cultural identity, challenges in intergenerational communication, and gains or losses in educational and economic opportunities (Pauwels, 2005;Romanowski, 2021).
