PASSAU, GERMANY - JANUARY 27:  Migrants and refugees arriving from Austria wait to be registered at a processing center on January 27, 2016 in Passau, Germany. The flow of migrants arriving in Passau has dropped to between 500 and 1,000 per day, down significantly from last November, when in the same region up to 6,000 migrants were arriving daily. German police only allows migrants to enter who say they will apply for asylum in Germany. Those who say they want to continue to other countries, such as Denmark or Sweden, are denied entry and brought back to Austria.  (Photo by Johannes Simon/Getty Images)
