“…On the other hand, the ever-increasing complexity and diversification of these various policy regimes explain some of the conceptual difficulties surrounding contemporary migrant irregularity, which a growing number of scholars are trying to overcome by questioning the strict dichotomy between 'legal' and 'illegal' migratory status. While some have suggested alternative concepts that capture a more fluid range of in-between statuses (Goldring et al, 2009;Kubal, 2013;Ruhs and Anderson, 2010), others emphasise the increasing diversity of potential paths into and out of irregularity (Black et al, 2006;Calavita, 2003;Cvajner and Sciortino, 2010a;Düvell, 2011), as well as a certain hierarchy among different kinds of irregular status (Chauvin and Garcés-Mascareñas, 2012;Cvajner and Sciortino, 2010a). It has also been shown that irregular migrants are often incorporated into some spheres of society (whether formally or informally) but simultaneously excluded from others (Castles, 1995;Chauvin and Garcés-Mascareñas, 2014;Cvajner and Sciortino, 2010b;Mezzadra, 2011;Ruhs and Anderson, 2010).…”
