The migrant sex worker character can be interpreted in multiple ways according to the interests, moral views and political goals of relevant stakeholders within this context. This work analyzes how the perspectives of security, gender and resistance, respectively promoted by government actors, associative agents and the subjects themselves reverberate in the empirical practice, that is, through the interactions of Brazilian cisgender and transgender sex workers with the other actors surrounding them and with whom they together configure the moral economy of the mobility of sex workers. More specifically, this thesis aims to investigate how the label of vulnerable and naive victim on the one hand, and the labels of criminal, pimp, illegal and transgressive on the other are produced and mobilized by the different actors involved in the regulation of sexual labor migration. The analysis carried out in this work is based on ethnographic-inspired research, describing the field of Brazilian prostitution in the French cities of Paris, Lyon and Toulouse. From this immersion, the thesis demonstrates how the articulations between the category of victim - of trafficking, of sexual labor exploitation, of patriarchy, of unequal capitalism - and the category of criminal - for pimping friends, for being clandestine, for feeding the black market, for exercising an immoral activity - are mobilized in this context. It reveals a highly nuanced and ambivalent reality, since Brazilian prostitutes are often simultaneously victims and autonomous, manipulated and opportunists, pimps and exploited.
