This paper examines the impacts of state policies and NGO advocacy on female sex workers’ identity and how they manage stigma. Comparing three groups of sex workers – those born and working in mainland China, those born and working in Hong Kong, and those born in mainland China who later migrated to Hong Kong and entered the sex industry – this paper suggests that differences in state policies on prostitution and the different degrees of visibility of NGOs campaigning for sex workers’ rights are related to three strategies used by sex workers to construct a positive self-image to counteract the stigma they face: gendered obligation fulfilment, professional work and responsible citizenship. The paper illustrates that stigmatized-identity management involves complex relationships among individual interpretation, selection and mobilization of gender, work and citizenship scripts, which are contingent on structural features of the environment and may change during migration and relocation.
