Social integration represents "the process, through which an individual becomes a part of a social system, accepting the values that define the normative order (..) through the conveyance of cultural models and dominant behaviour patterns provided by family school and primary groups" . According to such understandings however, the idea of integration is a concept, which can be related to "assimilation" (which does not entail the mutual exchange), that according to Castle and Miller: "can perpetuate the sense of marginalization and conflict" . According to what is stated by the Common Basic Principles for immigrant integration Policy in the EU, integration is ‘a dynamic, two-way process of mutual accommodation by all immigrants and residents of Member States' , accompanied by respect for the basic values of the European Union on the one hand and guaranteeing the practice of diverse cultures and religions under the Charter of Fundamental Rights on the other hand.
