Migrations are a global wave that societies and governments will face and manage with new policies and instruments. When we say Migrations, we refer to a complex and global phenomenon whose conditions, connotations and outcomes can be ambivalent for the countries of origin and the countries of destination. We define Migration as ‘the geographic movement of people across boundary with the purpose of establishing a new permanent or semi-permanent residence’. There are multiple reasons for migration. The contemporary international migration trends are the latest repetition of many population movements which reshape states and cultures. But we distinguish these migrations by the fact that states developed their administrative apparatus and tools for managing the migration flows.
