This ‘state-of-the art’ article on the role of deservingness in governing migrants’ access to social services situates our themed section’s contribution to the literature at the intersection between the study of street-level bureaucracy and practices of internal bordering through social policy. Considering the increasing relevance of migration control post-entry, we review the considerations that guide the local delivery of social services. Among others, moral ideas about a claimant’s worthiness to receive social benefits and services guide policy implementation. But while ideas of deservingness help to understand how perceptions of migrants’ claiming play out in practice, we observe limited use of the concept in street-level bureaucracy research. Drawing on theorisations from welfare attitudinal research, we demonstrate the salience of deservingness attitudes in understanding the dynamics of local social service delivery to migrant clients.
