This study examines the role of faculty in international students’ adaptation process to university life in Taiwan. In order to understand the perspectives of the participants, qualitative interviews were conducted from both faculty and international students. The business and engineering faculties were analyzed in this study. After the data collection process was completed, it was analyzed in order to look for similarities and differences among these four groups. The results show that the faculty plays an important role in the academic success of international students. The study identities that faculty members socially construct for international students both positively and negatively impact students’ academic performance. International students hold faculty in high regard, and their interactions with faculty can have a great influence over them. However, the issues of teaching styles and communication skills are viewed as moderators, which may significantly affect students’ performance in some ways. For this study, cross cultural management and adaptation theory explain how faculty perceptions influence international students’ adaptation and performance. Communication is key to students’ adaptation processes and vital to their academic success. The challenges of international students as reported by faculty, such as communication issues, language difficulties, insufficient knowledge of Asian teaching methods and cultural differences, can be addressed by providing additional educational opportunities for international students and training for faculty.
