This study targets international students immersed in the host culture of Asian countries and identifies the potential effects of such immersion on these students by drawing upon the review of literature. An overview of the results in this study shows that international students immersed in the host culture of Asian countries can be affected by such immersion and undergo different challenges such as culture shock. Those effects are found to be reflected from daily activities of intercultural communication which leads to the emergence of English as a lingua franca (ELF). When international students are also found to be affected in their motivation of foreign language acquisition and attitudes toward native speakers and the target culture, it is thus concluded that regardless of which language international students immersed in the host culture of Asian countries adopt for intercultural communication, they are definitely affected by such communication which is part of intercultural education and beneficial for them in developing worldviews and the competence of responding to world affairs in the global society of the 21st century.
