In principle, asylum seekers are not detained in prisons for the sole purpose of their asylum procedure. Asylum seekers may be detained during their procedure.
(Rejected) asylum seekers with psychological problems can be transferred to a specialised institution called Veldzicht, which offers psychological care. The transfer can be carried out voluntarily because the asylum seeker wants intensive psychological help, or involuntarily as a crisis measure. This option is also included in the Bill regarding the return and detention of aliens, which is still in the legislative process. This is only possible when the detention or the asylum seekers centre cannot offer adequate care and at the condition that the asylum seeker is kept separate from (foreign) criminal detainees.
Even though asylum seekers are not detained with criminals or in prisons, the facilities for their detention managed by the Custodial Institutions Service (Dienst Justitiële Inrichtingen, DJI) are very similar. During the border procedure, adults are detained at the Justitieel Complex Schiphol. They stay in a separate wing at the detention centre. Territorial detention takes place in Rotterdam for men and in Zeist for women and (families with) children. In November 2020 and July 2022, the Council of State ruled that DC Rotterdam was to be considered a special detention facility within the meaning of Article 16 of the Return Directive. The underlying intention of article 16 is to ensure that immigrants are separated from criminal detainees in detention.
