One of the core aims of higher education internationalization is to cultivate cross-culturally competent college students. Previous research has investigated various factors that can contribute to college students' cross-cultural competence (CCC). Nonetheless, most of these factors tend to be shaped in the physical environment. By contrast, little is known about the role of social media in achieving this goal in the virtual environment. According to the Uses and Gratification Theory, social media can enrich college students' cross-cultural experiences through social, cognitive and hedonic usage. Hence, this study has two objectives. The first objective is to discuss the roles of social media usage patterns in improving college students' CCC by reviewing prior literature. Further, since culture and language are intertwined, there is a growing consensus that intercultural teaching methods should be incorporated into teaching English as a foreign language (EFL). Thus, the second objective is to discuss implications for redesigning EFL curriculum aimed at improving college students' CCC.
