Since the 1986 Doi Moi reform, an increasing number of labor migrants and students leave Vietnam every year for better opportunities abroad. During the same period, members of the diaspora have been returning to the country. According to government estimates, over 500,000 Vietnamese return to Vietnam each year to work, live, and retire. Among these returnees are a group who have made Vietnam their home: the Western-born, second generation. This paper explores the significance of online community memberships in the construction of identity and belonging among Western-born Vietnamese who “return” to their ancestral homeland. Drawing on 32 online in-depth interviews with second generation Vietnamese living in Vietnam, from 11 disparate Western countries, it underscores how identity and belonging, state policies, and information communication technologies (ICTs) intersect to prompt and obscure the ethnic returns of western-born Vietnamese migrants.
