This article explores the use of online social networks for seeking and sharing information about marriage migration. In Europe, since the 1990s, this migration has faced heightened scrutiny. Laws and administrative practices have added complexity to immigration procedures. Manifold screening methods gauge the authenticity of relationships aligning with the host nation’s concept of a suitable family for integration. In this context, informal self-help groups emerged to offer support to those facing burdensome formalities and local administrative intricacies. Based on extensive qualitative fieldwork, this article examines the significance of these support groups, drawing on the concept of intimacy as a shared competency. Here, intimacy is conceived as an active relational skill that counterbalances the limitations of migration policies. The analysis transcends the division between online and offline modes of living, shedding new light on intimacy and extimité – the sharing of one’s intimate self with others for validation – in doing family.
