With the development of globalization, people in all parts of the world have more opportunities than ever before to connect with each other for a variety of purposes. Given that English is a lingua franca in the world, many researchers have emphasized the importance of enlarging students’ intercultural competence in the process of second language acquisition (Hall, 2002; Stahl, 2003; Arabski, & Wojtaszek, 2011). Thus, the researcher examined students’ intercultural competence (IC) through experiential learning in this study. Thirty-five students in the “Study Away from Home” program participated in the study in the spring semester of 2020. Intercultural Competence Scale (ICS) was administered to explore students’ intercultural competence before and after the program. In addition, a semi-structured interview was applied in the end of the program to probe the correlation with the quantitative results. The results showed that, except for affective orientation to intercultural interaction, there were significant differences in the knowledge of intercultural interaction, self-efficacy in intercultural situations, behavioral performance in intercultural interactions, and the display of intercultural consciousness. Specifically, students’ self-efficacy decreased because of the tension and conflict happening in intercultural contexts. This investigation suggests that, apart from teaching customs or traditions of different cultures, language teachers should also teach the values behind the cultures, which should be experienced and practiced by students as well.
