Introduction: the paper discusses some features of setting up the investigation of crimes involving foreign citizens as witnesses and victims, depending on their citizenship. The goal is to analyze the norms of international law and the legislation of the Russian Federation for the criminalistic significance and the influence of the citizenship of a foreign citizen involved in the criminal proceedings on setting up the crime investigation. Using the simulation method, the possible investigative situations were considered, during which the influence of citizenship of foreign citizens on the course of crime investigation was demonstrated. Conclusions: in practice, for the investigator and interrogator, the participation of a foreigner in the criminal process creates the need for additional organizational measures, which, first of all, are due to his / her citizenship to a specific foreign state. The efficiency of the investigation of crimes involving foreign citizens will largelydepend on the legal competence of the investigator in the matters of the migration legislation of the Russian Federation.
