The English language has become an essential means for communication and studies for international students globally. With the increasing number of international students trooping to China to study diverse courses which are taught in the English medium, there is a need to address challenges faced by international students from non native English speaking countries. The study adopted an embedded mixed method approach where face to face interviews and focus group discussions were conducted on freshmen international students taking English for Academic Purposes (EAP) in a specific faculty of a university in China. The interviews were supplemented by the Questionnaire of English Self Efficacy (QESE) to measure their perceived English self efficacy after the course. An online questionnaire on English Course Evaluation (ECE) was used to measure the students' assessment of the course.The findings of the study offer insights into the effect of the intervention, challenges faced by students during the course, and suggestions on things to consider during the implementation of English courses for non native English students in the future.
