-The main problem they face is the difficulty of renewing the "pink card", the document that certifies them as asylum seekers.
-Since the start of the operation Xenios Zeus in August of 2012, tens of thousands of people presumed to be undocumented migrants have been subjected to abusive stops and searches on the streets, and hours-long detention at police stations.
The main complain of the Nigerian community has to do with the "pink card". This is a document you get when you ask for refugee status, and certifies that you have applied for asylum. More than 30.000 asylum application including Nigerians’ are currently waiting to be examined, the mainly part of the process of obtaining refugee status. Some of them have been waiting up to 10 years just for having this interview, and meanwhile they have to continue renovating the "pink card" every six months. But this is not easy for them. They report trammels, abuse and misbehavior from the police. Some of them talked about police taking their "pink cards" away, for no reason, or just destroying them. As a result asylum seekers can be undocumented for long periods, with some serious consequences like losing their jobs.
Being undocumented also make them perfect victims of police operations like Xenios Zeus, an epic-scale sweep operation aiming at cracking down on irregular immigration in Athens. Xenios Zeus stigmatizes migrants and asylum seekers, and is a dangerous distraction from the real policing challenges the country faces.
