Arrivals declined sharply with the closure of the Balkan migrant route in March and the subsequent agreement between the European Union and Turkey to stem the flow across the Aegean Sea to Greece. The Federal Office for Migration and Refugees, which has been beefed up in the course of Europe's migrant crisis, decided last year on more than 695,000 asylum applications, more than twice as many as in 2015. Chancellor Angela Merkel, who faces a national election later this year and still draws criticism for her welcoming approach to migrants in 2015, has promised a "national effort" to ensure that people who aren't entitled to stay go home.
