In 2019, 33,523 North Korean refugees were granted citizenship and lived in South Korea. There is growing concern that rather than guaranteeing participation, their citizenship is associated with marginalization, alienation, and isolation. Guided by an occupational science perspective and Straussian grounded theory, this study explored how they participate in society through engaging in everyday activities using 10 semi‐structured interviews that were analyzed using open, axial, and selective coding. It found that the South Korean governmental stance toward reunification, compounded by ethnic homogeneity, eased the participants' transition to the host society. In response, participants engaged in or pursed activities they hoped would prove useful for the reunification of Korea. Readying for reunification encapsulated a meaning participants attached to their everyday activities while pursuing citizenship of South Korea. This article concludes by recommending the urgent need for social outreach initiatives, where North Korean refugees utilize their trans‐national knowledge for the reunification.
