The article develops three arguments: 1) collective regularizations, very visible and aimed to involve big numbers of immigrants, occur mainly in Southern Europe, where segmented labour markets have pulled huge volumes of irregular labour between the end of ’80 and the economic crisis started in 2008; 2) common regulations of entries in the European space (e.g., Schengen agreements) have demonstrated to be inadequate to give answers to labour market needs of Southern Europe: amnesties for irregular migrants can be seen as a solution post-hoc to contradictions between policies and markets; 3) mainly in Southern Europe, but not only, irregular condition from a legal point of view appears temporary and changeable, whereas legal norms appear selective and applied with different degrees of severity.
