This study is a descriptive correlation study to investigate the mediating effect of familiarity and social support in the relationship between grit and academic continuity for Mongolian students. A survey was conducted from May 1 to June 30, 2021 on 124 Mongolian students from universities across the country using Google questionnaires. As a result of the study, grit had a significant effect on the familiarity and social support of Korean culture. The intention to continue school was significantly influenced by grit, familiarity with Korean culture, and social support. Grit directly had a significant effect on academic continuity, and familiarity with Korean culture and social support had a partial mediating effect in the relationship between grit and academic continuity. Based on the results of this study, it is necessary to increase grit and seek counseling and education programs to help using Korean cultural familiarity and social support systems.
