This article is about the present state of migration in the European Union. The fears expressed by some countries that after the last enlargement a big amount of migrants will enter on the Schengen area are not founded. The European economy is now dependent on cheap labor force offered by migrants. More than that many migrants that are now working in European Union old member states will return to their countries as a result of economic growth. The results of pools show that a little percent of people from new member states are ready to migrate to the old members. So in present, migrants are a necessary evil for European Union.
