It would never be an easy decision for a person to leave his country of birth and look for his fortune elsewhere. There are a number of reasons why migrants leave their countries.
These so-called push factors exist in the poorer or conflict-weary regions of the world and some of them are defined as:
• dissolution and disintegration of multicultural states, accompanied by religious and ethnic conflicts;

• comprehensive social security;
• positive economic situation;
• democratic systems of government, political and social stability;
• historical links;
• common languages;
• existing communities;
• expectations (EUROPOL, 2004).

This distinction came to clarify various categories of migrants and responsibilities of the host states towards these migrants. When it comes to economic migrants, it can be argued that the individual host states have had a higher leverage in the face of international
