The concept of «other-ethnocultural neotraditionalism», which implies the reproduction of ethno-cultural traditions and behavioral practices in a different cultural and geographical space is introduced. An analysis of the features of this process, using the case of migrants, led to the conclusion that the stereotypes and misconceptions of the host community regarding migrants, including those based on the rejection by this community of other-ethno-cultural neotraditionalism of migrants, hinder their successful sociocultural adaptation to the new environment, and stimulate the process of enclavement. The heuristic potential of the concept of other-ethno-cultural neotraditionalism lies in the possibility of fixing various strategies for sociocultural adaptation of migrants to a new environment, based on the actualization and reproduction of ethnic identity on non-traditional grounds.
