Abstract
Arousing the passions and the divisions, the migration is apprehended by some Europeans as a danger for the national identity and is approved by the others as a source of cultural diversity. Many forms of illegal immigration are observed. The migrants can enter a member states by land, air or sea. Also a lot of these illegal entries are made thanks to the utilization of false or forgotten documents and organized crime networks. Nevertheless many people penetrate legally thanks to a visa but exceed the time authorized or modify the aim of their stay without the agreement of the government. Finally some asylum seekers do not leave the country even after a negative response. The Europeans have emigrated to places all over the world for centuries. Europe has received supplies from a lot of foreign cultures and populations during its history. The migration process is a huge part of the common history. It is a natural phenomenon of the exchanges and relationships between human communities.
