In the scientific work, some problems of adaptation of students who arrived from far abroad to the process of studying in higher educational institutions of Russia are considered. Examples of living together in dormitories with Russian students are demonstrated, and the positive and negative aspects of conducting a common life are shown. Such difficulties usually arise due to different cultures, lifestyles, food preferences, religions, and attitudes to learning.
