ABSTRACT Current literature on internal bordering has suggested understanding health care as a key migration control field. This article takes a closer look at the humanitarian medical offices in Frankfurt am Main, Germany, and patients from Romania and Bulgaria in precarious life circumstances. It addresses the strategies identified in the accounts of frontline workers beyond the mere provision of access to free and anonymous medical attention. Based on 16 interviews with medical staff, social workers and administrative officers, two approaches emerged. One clearly strives for the formalisation of the human right to health care in close collaboration with, or by challenging the local bordering actors; the other insists on bypassing any point of contact with them, focusing exclusively on informal and direct solutions. The interviews showcase how the resulting strategies can contribute to internal bordering and debordering on an urban scale, and affect the individuals’ trajectories as patients and as migrants.
