Drawing on biographical and migratory experiences gathered from Chinese marriage-migrants in Taiwan, this paper investigates the link between migration, subalternity and emotion. We examine how emotions are socially, temporarily and situationally constructed by migrant women, positioned in a condition of vulnerability during migration. Conceptually, we advance that emotions can be turned into resources, practices and competences that sustain migrants' social, economic and cultural positioning in the society of arrival. Through the identification of three empirically-rooted states of emotionsimaginative, implosive and mutualwe claim that, in a context of social contempt, familial exclusion and economic marginalisation, migrants' individual and collective performance of emotions contributes to 'undo' a condition of subalternity. Such states are purposely experimental and incomplete. Whilst they are as temporary and mutable as migrant women's emotional experiences and practices, this paper proposes that they could serve as a methodological and analytical tool for future research on migration and emotion.
