Theoretically embedded in the migration/social policy nexus, this paper investigates cooperation with return (CWR) as a policy tool to remove practical deportation barriers for third-country nationals pending removal. Based on legal and policy documents and expert interviews with stakeholders in Austria and the Netherlands, the paper asks how CWR is implemented and what influence it has, both on migration control aims and on access to social rights. We argue that the politicization of the issue and diverging interests between policy networks of welfare and migration affect the regulation and implementation of the tool. By comparing the use of CWR within two country contexts, the analysis presented here adds valuable insights on features of governmental instruments in response to the “deportation gap”. The paper further adds to the literature on sanction-oriented, personalized migration policies.
