"While it has been estimated that there may be from 5 to 8 million undocumented migrants in Europe, they largely remain invisible in the eyes of policy makers. This situation puts enormous strain on local actors such as NGOs, health care and educational professionals, and local authorities, who often work with limited resources to defend undocumented migrants’ fundamental rights ...These local actors are confronted on a daily basis with situations confirming that irregular legal status is an obstacle for a sizeable part of the population in accessing basic social services. Professional groups experience clashes between what their professional ethics tell them to do and the incriminatory discourse regarding undocumented migrants." (Quoted from paper)
