The article try to contribute to the immigration "debate", pointing out that an overall approach to the problem of "social integration" in sociological studies and policies planning in Europe and more in Italy along with an over evaluation of ethnic - national - religious background of migrants, not rarely "polluted" with "national" stereotypes, have limited the impact of analysis on multicultural societies. Shakespeare’s Othello is the tragic figure of an "immigrant" made stranger in a society where he had been successfully "integrated". Integration itself is an "umbrella concept" containing different social processes in different social environments. Social studies on stranger psychological background in migrants biographies, are presented along with very well known study cases of second generation migrants as Rushdie’s "Satanic Verses" story. The modest "thesis" of contribution emphasize that a "stranger perspective" in a social context of full citizenship system, could help to build a real multicultural society.
