In the globalized world of the 21st century, we can consider multiculturalism as an inevitable element in everyday life, which encourages us to notice the differences between our own culture and the cultures of other nations. Communication, appreciation, and acceptance of differences are just some ways of suppressing prejudices toward others, which is why developing one's intercultural competencies is important. In order to create an interculturally competent society, it is necessary to start with the educational system as a prerequisite for removing intercultural borders. To achieve this goal, teachers and students should develop cultural intelligence, focusing on the cognitive, metacognitive, motivational, and behavioral dimensions. The aim of the paper was to investigate the connection between learning foreign languages and the cultural intelligence of young people. The results showed that female respondents are more successful in the behavioral and cultural dimensions compared to male respondents. Surprisingly, the results showed no correlation between age and cultural intelligence, while the results of the final grade in English and cultural intelligence showed a correlation. Also, students who spent time abroad as part of projects, student exchange, or private travel proved to be more successful in the behavioral and cultural dimension compared to students who did not have this experience, which was expected.
