European countries have been erecting thick walls aimed at preventing unwelcome guests from entering. The institutional, legal and even physical barriers are have the intention of stopping flows of political and economic migrants who try to make their way to the imaginary dreamland of a welfare state. All these regulations carry the label of 'New Policy', and the continent itself has been called 'Fortress Europe'. At the same time states of the European Union are consolidating their powers in creating a common unified immigration policy. This paper analyses both: the 'new policy' and the process of unification of the immigration regulations in the EU. It goes back in time showing the emergence of immigration policy regimes. Moreover, it tries to bring to light the barely existent 'tackling of root causes'.
