Every year, a considerable number of Sri Lankan students migrate overseas to further their studies. In comparison to previous years, the total number of students emigrating has increased significantly. Especially, in such countries, many migrant students are able to find new opportunities for their career development other than furthering their education. This qualitative research aims to examine the language alienation of Sri Lankan students studying overseas and how it has hindered the achievement of their academic outcomes. Ten migrant students studying in Canada and Australia for more than six months were selected as participants in the study. Semi-structured interview was administered to gather data and Thematic Analysis (TA) was used to arrange, analyze and interpret the data. The findings of the study revealed that 90% of the participants experienced language alienation upon arrival in these countries. They could not complete many of their daily tasks, such as making friends, understanding lectures, and participating in classroom events, due to the language barrier. Participants reported that the inadequate opportunity for enhancing their English communication skills in ESL classrooms in Sri Lanka is the key reason for this situation. As they claim, Sri Lankan primary and secondary education should give equal significance to all the English skills in the English curriculum rather than prioritizing writing and reading in examinations. This claim points to the need of practising speaking and listening in ESL classrooms without focusing only on examination-oriented teaching.
