This requires a theoretical rethinking of the conceptual apparatus, not only in relation to the concept of integration of immigrants. Not only in terms of identifying indicators of this process. But also more broadly — in relation to the definition of the concept of population migration, in general. The article makes a methodological attempt to show that when considering integration, as an integral part, the final, third stage of population migration — adaptation, in accordance with the theory of three stages of population migration, most fully presented in the works of L.L. Rybakovsky, it seems possible more clearly to determine the tasks of the integration policy of the Russian Federation. Since this approach clearly separates the processes of adaptation, integration, arrangement at the stage of settling — in at the place of settling. Gives a clear understanding that integration is the prerogative of only migrants who belong simultaneously to the type of interstate and permanent migration. And only they, objectively, should be the object of integration policy, which should be an integral, integral part of immigration policy. But with its own specific tasks for its object — interstate permanent migrants. Such a methodological approach, to the greatest extent, corresponds to an individual approach to the regulation of the integration process, makes it possible to more effectively use the mechanism of integration con-tracts to increase the responsibility of the individual and society. Implemented at the local, municipal level, at the same time — the level of self — government in the Russian Federation, such an individual method of integration policy is most consistent with the figurative understanding of integration as a road with oncoming traffic, since it also contributes to an increase in the civic identification of immigrants and national solidarity of society. It implies a targeted mutual determination of rights and obligations.
