Abstract: The article examines the issues of formation and legal regulation of the institution of administrative expulsion in the domestic legal system, as well as special institutions – temporary detention centers for foreign citizens of the territorial bodies of the Ministry of Internal Affairs of Russia. These institutions are, under the jurisdiction of the Ministry of Internal Affairs of Russia and possessing administrative legal personality, specialized regime law enforcement agencies established in order to comply with legal requirements in terms of: implementing the execution of administrative expulsion from the country, deportation or readmission, as well as isolation from society of immigrants subject to forced expulsion from the Russian Federation, deportation or readmission. The socio-economic and political changes that took place during the time period under consideration had an impact on the development of the democratization of society, manifested in respect and observance of human rights and freedoms in modern Russia, and led to the formation of legal norms governing the organization and activities of special institutions.  The analysis of legislative acts related to the legal regulation of administrative expulsion and special institutions was carried out, statistical data for 2022 were analyzed. The authors identify the current problems that arise in the activities of Temporary Detention Centers for foreign citizens, related both to imperfect interaction with other government agencies (FSSP), and personnel issues, and logistical support. In connection with the identified problems, the authors propose certain proposals for improving the activities of temporary Detention Centers for foreign citizens. In particular, it is proposed to increase the number of personnel; reduce or not involve civilians at all in the protection of temporary Detention Centers for foreign citizens; differentiate the activities of the Ministry of Internal Affairs and the Federal Bailiff Service so that this service is actually engaged in expulsion and deportation, that is, escorted foreign citizens from temporary Detention Centers for foreign citizens to places of official expulsion.
