This study investigates the transnational experiences of young Taiwanese-background children living in Australia, who sojourn to their parents’ homeland during the school holidays to improve their linguistic and cultural skills, as reported by their mothers. Although this appears to be a frequent practice in the Taiwanese diaspora, showcasing the agency of this community, little research has systematically investigated this practice, and in particular its impact on the children and their families. Data for this study were obtained through online questionnaires and semi-structured interviews with mothers who engage in this practice, to gather information on family histories and participants’ backgrounds, family language policies, and parents’ perceptions of children's experiences and challenges. The data show that parents aim to enhance their children's proficiency levels in the home language as well as their Taiwanese identity. Children, however, take an agentive role with regard to identity choices, so parents’ aims are not always fulfilled. Sojourning is presented as a clear example not only of enacted family language policy, but also as an explicit management practice, positioning the Taiwanese diaspora within both their new as well as their old homeland.
