5. Registration and screening: A wheel of misfortune cases a re-screening or a correction of nationality took place. Representatives of the Nigerian embassy visited the detention centre for the authentication of Nigerian citizens. M.K. remained in detention for the full length of six monthswhile A.A., on April 12, was transferred together with a group of Nigerians to a detention centre in Athens. This group was scheduled for deportation from Athens to Lagos, Nigeria. A.A.’s whereabouts are unknown until today. In a second fax of Max 2011, the GCR-lawyer asked the authorities to inform her where A.A. was, if he was still in detention or deported. There has not been any answer so far.64 Such errors also have an impact on the duration of detention, which can vary from some days to months, since people with specific nationalities are usually being detained longer before their expulsion to Turkey or to the country of origin as registered. There are cases in which the authorities themselves question the screening result. In such cases, the period of detention and further implications remain unclear. When asked for more detailed information, authorities simply replied that the respective detainee had to wait in detention until Frontex could identify his/her »real« nationality in a second screening. Additionally, as they said, he/she could prove his/her claimed nationality by providing the authorities 23 with evidence such as copies of his/her identification papers from the country of origin. This whole procedure is not known to the detainees and, under the above described detention conditions it is not feasible for the detainees, without the help of a lawyer, to challenge the initial screening procedure. Furthermore, the number of detainees registered as of »unknown« nationality remains unknown. »Maybe somebody can survive three months in here, but nobody can survive six months«. H.A. was detained in a mixed cell.65 She had come to Greece on her own and spent more than one month in Tychero crying every day. Nobody was speaking her language. She was extremely afraid. In her screening interview reportedly she was told that she belongs to Al Qaida, thus she feared to be detained for a long period and she feared deportation. It is not clear, if she understood correctly what the interviewer had told her, since he was not speaking her language and there was no interpreter. She just remembers that the interviewer was dressed in civil clothes and that he had a laptop. He was speaking English with her. Halima had claimed to be from Somalia, but her nationality was questioned by the screening officers. As some officers informally told us, detainees whose identities remain questioned are registered as of »unknown nationality« and have to be re-screened.66 »Here they have no idea about the Palestinian exile!« A.M. from Palestine67 ■ A.M. from Palestine was registered wrongly as Iraqi citizen. He was arrested on October 6, 2011 and transferred to Fylakio. A.M. grew up in Iraq as a refugee together with his family. During the war in Iraq they escaped to Syria. He has a broken leg and bullets in his arm and his shoulder. The injuries stem from the conflict in Iraq. »During registration I said that I am Palestinian. The interpreter was a woman from Egypt. The officers took my mobile phone and checked my calls. The officer told me I should tell the truth so they could help me, otherwise they would put me in prison. Here they have no idea about the Palestinian exile!« Tyhero: Migrants are waiting sometimes for days outside without any sanitary infrastructure for their registration 64 GCR fax ref. no. 24/2011 65 H.A. from Somalia; November 19, 2010 – Tychero 66 N.M. from Afghanistan; November 19, 2010 – Tychero 67 A.M. from Palestine; October 10, 2011 – Fylakio
