There is a widespread concern on issues of acculturation due to diversity in the world. More and more students go abroad for higher education recently. Students come into contact with different cultures in their study abroad experience. Students would also encounter troubles and obstacles because of culture shock. The present study aims to investigate and compare academic integration, social integration, and language integration of two groups of international students in Taiwan. Group 1 included Malaysian and Chinese international students who can speak mandarin Chinese. Group 2 included international students from other countries who cannot speak Chinese. A total of 110 international students participated in this study. A questionnaire was used to measure students’ academic, social, and language integration. In addition, interviews were carried out to understand students’ opinions on academic relationships, academic participation, friendship, and activity attending. The results showed that both groups integrated well in Taiwan. Group 2 was significantly higher than Group 1in terms of friendship. The results indicated that the acculturation of international students in Taiwan was good. In academic aspect, international students benefited from local students and teachers, and were more interested in different classroom environment. In social aspects, the international students felt that local students were friendly and willing to help others, and they enjoyed extracurricular activities. In terms of language, Chinese native speakers mentioned that there are slight differences in Mandarin used in Taiwan, but the differences did not influence communication. For other international students, using English most of the time had no influence on their life and study in Taiwan.
