Foreigners represent an increasing part of people who move their residence from one to other Italian municipalities. This article aims at explaining this feature of internal migration phenomenon, trying to answer some main questions. Are there any differences in the internal migration phenomenon, concerning intensity, migratory typologies and directions, between foreigners and Italians? Are there any differences even between foreigners depending on their nationalities? To which extent personal conditions or different migratory contexts influence the internal migrations? In this pattern, is Campania region still a transition area for migration flows or its role has changed over time? The number of foreigners who moved their residence in 1998 was less than 70.000 and in 2006 it became more than 200.000 as a consequence of the general increasing of immigrants presence. The internal migration level of foreigners has always been three times more than the Italians one. The recent immigrant communities are more mobile than the ancient ones, especially if we consider the ancient communities living in the metropolitan areas.
