Assisted Voluntary Return (AVR) is a central component of European Union (EU) member states migration management policies and has grown in popularity over the past two decades. At present, all EU member states have active AVR programmes, however, despite the growing prevalence of these programmes there has been a dearth of research and evaluation on AVR. In addition, a common goal of these AVR programmes is to achieve a sustainable return, but this term lacks a commonly used definition, making sustainable return an ambiguous policy objective. This paper takes stock of the most recent research on AVR focusing on decision making in the uptake of AVR, reintegration, and sustainable return. It is argued that it is time for a fundamental shift in our underlying assumptions regarding sustainable return in the field of AVR policy and practice. The working paper addresses key research gaps in the field and poses recommendations on how to move the agenda forward on AVR.
