Undesirable migrants can include asylum-seekers believed to have committed crimes before arriving in the host State, immigrants who had their status revoked for having committed crimes in the host country, or immigrants who were not granted a status, or had their status revoked because they are considered to pose a current or future security concern. These undesirable migrants can be unreturnable because of different legal and practical reasons. This article describes the size and characteristics of this group and discusses which policy measures the Dutch Government takes to deal with this group, in particular in relation to access to permits, return, relocation, and prosecution. It concludes that the Dutch approach to bar Article 1F-excluded persons under the Geneva Convention and Protocol Relating to the Status of Refugees from all residence permits is in certain circumstances at odds with European Union law.

荷兰不受欢迎但无法返回的移民

不受欢迎的移民可能包括被认为在抵达东道国之前犯罪的寻求庇护者、因在东道国犯罪而被撤销身份的移民、未被授予身份的移民，或因他们的身份而被撤销身份的移民被认为构成当前或未来的安全问题。由于不同的法律和实际原因，这些不受欢迎的移民可能无法返回。本文描述了这一群体的规模和特征，并讨论了荷兰政府采取哪些政策措施来应对这一群体，特别是在获得许可、返回、搬迁和起诉方面。
