Abstract : Taking care to describe a board of the stranger immigration in FRANCE as it is existing nowadays, we connect to this descriptive work a definition of the integration in the contemporary french society. It is important after this to present the general context of the punishable acting out, and then to describe the subjacent psychic mecanisms of these. It authorizes us in this way to spread out reflexions about some importants dimensions in this clinical research, like for example, the "double cleavage". About psychics mecanisms, we accord a big place at rites, agressivity, violence, and of course at the ties between migration and juvenile delinquency. In the reflexion about the "double cleavage", we take a reflexion moment on the cultural appartenance and on the identity, and we also measure the ties between family 's history and the cleavage between "the inside" and "the outside", a bond on which take a big importance the notions of relationship, dependance and transmission, and the fact to navigate between two cultures. Then, we meet notions like the vulnerability of self esteem, the cognitive distorsion, individual violence, prejudiced people, etc. This leads us to consider the ties between immigration and assimilation, taking care to grasp the importance of the notion of honour for youg mens who are living in the slums, and who are coming from migrant people. This work leads us to be interested by the ties between delinquency and self esteem, and by the ties between delinquency and anxiety. The first review leads us to take care about the notion of the default of psychic elaboration and about its acting out so well-defined. The second review gives us the occasion to be interested by the analysis of the cognitive pattern of the treatment of the specific information of anxiety, so, we consider in this way the notions of vigilance and social phobia. A last review authorize us to evoke the influent place taken by the exile in the family story. This should have a tie with some violence forms or some punishable manifestations which are rising in the private space or in the public space.
