The female mainlander spouses in Taiwan suffer from treatment as ambivalent citizens with incomplete citizenship rights. On the one hand, this study examines how national and gender factors work together to exploit mainlander spouses’ citizen rights, including civil, social, and political rights. This study emphasizes that citizenship is a multi-dimensional concept that contradicts with national identity and patriarchal order. On the other hand, this study stresses that the exclusive effects of national identity and the discriminatory effects of patriarchy on mainlander spouses are not independent; rather, national border controls often rely on the patriarchal order for maintenance, justifying and deepening national domination. By analyzing the existing documents and law texts, as well as conducting interviews, this study shows that in the process of attaining citizenship, national sovereign and hierarchical patriarchy together deploys a dual domination. This dual domination system deploys different ways of mixing effects on different dimensions of citizenship, which could be summarized as: the inside-and-outside division of civil rights, the more-or-less discriminatory distribution of social rights, and the public/private division of political rights. In comparing the three kinds of citizenship rights of mainlander spouses, their political rights have been most seriously and almost completely deprived; next, their civil rights have been restricted in many ways, and lastly, their social rights have been vested with prejudice.
