The Legal Regulation of the EU Immigrant Integration Policy
... the EU immigrant integration policy: ‘soft law’ instruments adopted at the level of the EU; provisions on immigrant integration contained in the legal acts of the Union; relevant national legislation. I conclude that the system of legal regulation of immigrant integration in the EU is two-tier. General principles are established at the Union level and legally binding rules are formulated at national levels.
