INGELHEIM, GERMANY - AUGUST 27: Afghan migrant seeking political asylum pictured at the registration center on August 27, 2015 in Ingelheim, Germany. German Vice Chancellor and Economy and Energy Minister Sigmar Gabriel visits the registration center, where refugees stay only for some weeks. Germany is expecting to receive at least 800,000 migrants and refugees this year, and though those from war-torn countries like Syria will likely asylum, German politicians are seeking means to expedite the return of migrants from countries deemed safe, most notably those in the Balkans.
