Social workers are increasingly globally mobile, pursuing employment opportunities that combine professional and lifestyle projects. Social work skills and practice are embedded in cultural, linguistic and nation-specific legislative competencies. The current article engages with the interplay of a fast-moving social work and immigration policy context and the role of inter-European social workers, using England as a case study of destination. Based on registration data of non-UK qualified social workers (2003–2017), a survey of 97 stakeholders from 27 European Union countries and focus group discussions, it investigates trends and challenges of transnational social workers (TSWs) in England. The findings highlight a dynamic process of social work education and immigration policy reforms during the past decade that was associated with a significant change in the volume and profile of TSWs registered to work in England. Data from European stakeholders further highlight two key findings: first, there is evidence of an increased role of inter-European social workers in most of Western European countries; second, the process of social work qualifications’ recognition within Europe remains considerably variable. The implications of the findings are discussed within the context of continued inter-European policy and political changes.
