Drawing on the findings from in-depth interviews with Vietnamese international students studying at Australian universities, this article presents insights into the sociological influences that stem from international students' social networks, at home and abroad, and how they impact on students' aspirations and engagement in international education. Underpinned by Bourdieu's social capital framework, this article critically challenges human capital ideology for its assumptions of individualism and utilitarian function of education as economic goals. The implication for international education providers is to create learning and living opportunities that consider students' social and cultural conditions so as to develop their capacity, self-determination and citizenship.
