Now, transnational migration is not a special phenomenon limited only to particular areas. As globalization accelerates, human transnational migration has become a universal phenomenon. Some migrants retain their original nationality living in their new countries they migrated to out of the territorial boundary, or some become naturalized citizens of the new country. Since 1990, Korean society has suffered multicultural transformation through a fast growing migration. As various types of foreign migrants continue to come in, the issue of nationality or citizenship is being magnified as an important controversy. In particular, unlike migrant workers who are classed as temporary migrants, marriage immigrant women organizing a family which is a standard unit of Korean society and taking charge of reproduction are able to settle permanently. But marriage immigrant women are immigrants, and they lie concurrently in a position of minority. So they are doubly an object of exclusion. Although they are an important member of Korean society, they still stay in an unstable and dependent position. Therefore, a review on the citizenship of marriage immigrant women is significant in that it makes reflective introspection on awareness about foreign immigrants and a social integration method possible.
