<p>If genre approaches have highlighted how women are protagonists of migration processes, they also have shown the continuity of the reproductive role, related with care, in the definition of those trajectories in global scale. On our qualitative research with Paraguayan migrants dwelled in an Argentinian city (Gran Rosario), between 2010 and 2014, we confirm that point in their forms of insertion and relations, related with domestic work and care practices. We propose to deepen the bases of those forms of participation, considering&nbsp;different parts of our ethnographic register and thinking about them in terms of inscription and belonging. Such aim is approached from exchange category, classical anthropological tool, in the production of specific social relations and the value representations intervening in the role of genre and care. Our aim is to review the mechanisms presents in the structuration and agency of genre in these trajectories.&nbsp;</p>
