The aim of this paper is to test new indicators about integration. The more integrated people are, the more the relations they have with the State will be normal. These relations can be a sign of normalization in the new society. Legal Residents have very accurate data. Amnesties are rather the same. On the other side, Census and Padrón are voluntary. People do not equally trust the State. A greater trust in the State matches with greater success rates in the regularization processes, for people carrying out voluntary registration. The more immigrants relate voluntarily with the State, the more possibilities will they have of getting residence permits.
