Shelter services are offered to vulnerable migrants who need protection, and to migrant men, women and children in a situation of homelessness. Shelters can be open for all migrants and/or for a specific nationality or a certain category. As a matter of example, shelters can be offered exclusively for victims of trafficking (VoTs), survivors of sexual and gender based violence (SGBVs), children and un-accompanied minors (UMC). Shelters can also be gender-specific.
