There is one nation in Europe that could use immigrants: Serbia.

A parliament-appointed rights official in Serbia has suggested that the country, blighted by years of depopulation, should ask migrants flooding through the Balkans from the Middle East to settle in hundreds of empty villages.
Birthrates in Serbia have been falling for decades and, coupled with the departure of thousands of young people in search of work in western Europe and North America, the population has fallen more than five percent since 2002.
Hundreds of villages are largely devoid of people.
“We should consider offering them (migrants) to stay in the parts of Serbia that are empty,” Brankica Jankovic, Serbia’s Commissioner for Protection of Equality, told B92 TV on Tuesday.

Of course there are skeptics and problems with the plan that would have to be resolved. For instance, there are no jobs in those regions, which is why people have left.
What most people don't realize is that a large percentage of migrants into nothern Europe aren't from Africa or Asia. They are from the Balkans.

Of the 196,000 people who had filed an initial application for asylum in Germany by the end of July, 42 percent are from the former Yugoslavia, a region now known as the Western Balkans.
The exodus shows the wounds of the Balkan wars have not yet healed. Slovenia and Croatia are now members of the European Union, but Kosovo, which split from Serbia and became prematurely independent in 2008, carves out a pariah existence. Serbia is heavily burdened with the unresolved Kosovo question. The political system in Bosnia-Hercegovina is on the brink of collapse, 20 years after the end of the war there.

One thing is for certain: Europe has to do something about all the migrants.

“The political situation regarding migration and migration policies in the EU is completely out of control,” said Crepeau, who is a law professor at McGill University. “At the moment the debate is driven by fantasies and myths: ‘Migrants take jobs, change our values; we’re overcrowded.’”
“They are coming and they will continue to come, and there’s nothing we can do about it,” he said.
Crepeau added “There is no military solution" that would stop the smugglers paid by many refugees who want to enter Europe. “All we can do is organize the flow,” he said.
