This research focuses on how Indonesian Chinese mothers define their layered identity as new residents in Taiwan where they practice their citizenship. In Taiwanese multicultural society, an enormous number of Indonesian Chinese women migrated to the country through marriage. Using the concept of "self definition," this research examines how Indonesian Chinese mothers recollect their multiple identities after migrating to Taiwan and interacting with Taiwanese society. Interviews were employed to identify and interpret Indonesian Chinese mothers' identities. This research finds that Indonesian Chinese mothers had to contend with their identity when they began to integrate into Taiwanese society, which is referred to as Chinese society. The contradictory identities they faced in their native country brought up recollections of the ambiguous identities they encountered while they were threatened as a foreigner in a place where they ought to be accepted as members of society.
