This paper focuses on transformations of the EU migration space in the period that goes through the 1990s, until the 1 January 2007, the day that sanctioned the sixth EU enlargement with the accession of Bulgaria and Romania. The last date is actually a starting point to try to identify the empirical form and political features within today’s migration scenario in the enlarged EU.
