Abstract: This study aimed to investigate oral communication problems among Yemeni high school English as a Foreign Language (EFL) students in Malaysia. The data was collected through a questionnaire and interviews. The questionnaire was adapted, as it dealt with possible problems experienced by EFL students. Therefore, 40 Yemeni high school students studying at an international Arabic school in Kuala Lumpur participated in the study. To triangulate the questionnaire data, six students were interviewed. The results revealed that the oral communication problems of Yemeni high school EFL students could be categorised into three factors. Firstly, teachers were focused on the grammatical aspect while neglecting the practical side of the language and they did not encourage their students to speak English in class. Secondly, the curriculum was not designed to promote and enhance oral communication since students had very limited drills to practise orally. Thirdly, most of the students were not confident using English as a means of communication both inside and outside the classroom.
