In line with international and national legislation, the Netherlands offers certain services, including a temporary residence permit, to third country nationals who have fallen prey to human traffickers. Over the years, concerns have been often expressed about the perceived misuse of this regulation by foreigners who aim at legalising their stay. Based on interviews and file analysis the present article seeks to provide insight into to what extent it is possible to measure this misuse and the policy implications of the findings. In addition, the authors take into account non-use of the programme. The article confirms existing worries about misuse, provides indicators for misuse, but also concludes that at the level of individual cases practitioners cannot discern misuse from rightful use. At the same time, there are also groups that fall outside the reach of the programme. The article concludes with some policy recommendations on the basis of the findings.
