« Exile » is presented in literature as an awful experience where the subject cries desperately after the lost object. Freudian psycho-analysis shows how important it is for the infant to get exiled from the primordial Wohl. The Lacanian definition of « exile » suggests to talk about « exiles », a plural, i.e as a structural disharmony. We have, therefore, wanted to examine the relationship between « exile », foreign langage » and their function for a foreign patient. The other side of our work is to examine the effects of exile upon the next generations. Actually, the main question is in what way both exile and foreign langage are symptoms when the father’s function is inefficient. We have based our everyday work with foreign patients upon a clinical approach which respects the psychic structure, the symptom and the various solutions or subjective inventions looking for a place in this world among men.Key words
