Abstract
Migration has existed since the beginning of mankind. The phenomenon has not been ceased in time, but it has changed and acquired new forms. Migration processes are conducted simultaneously and they are increasing in many countries. One of the long term results of this development could be the emergence of multicultural societies, tending towards new concepts of citizenship or national state. Most of the developed countries have become diversified and multiethnic societies, and those who have not reached this level yet, have turned decisively in this direction.
The social consequences of migration are as important as its influence on the economy. The regulation of the migration processes supposes the application of legal, administrative and socio-economic measures that are aimed to stimulate or limit the migration of population in or from the country, to ensure the respect of the migrants’ rights, to fight against both the illegal migration and illicit trafficking in human beings.
