The present paper focuses on transnational families of lesbian, gay and bisexual (LGB) migrants and addresses their peculiar absence in sociological and geographical perspectives across migrations, families and sexualities research. It draws from a study of middle-class LGB migrants who are married or raising children with a same-sex partner in Belgium and the Netherlands and their parents still residing in select Central and Eastern European (CEE) countries with constitutional protection of heterosexual marriage. The goal of the study is to examine how intersections of class and sexualities shape CEE LGB migrants’ trajectories and transnational family practices. The analysis is based on one life story, situated in a comparative framework. The present study approaches the middle-class experiences and non-normative sexualities of CEE migrants as continuously reappearing and disappearing privileges and disadvantages. From this viewpoint, the study highlights class advantages as consistently alleviating the disadvantages of non-normative sexualities, but also simultaneously bringing both further restrictions and additional benefits to the married CEE LGB migrants, particularly those with children. These restrictions are best reflected in the limits to further mobilities that stem from the risk of losing extensive legal protection of same-sex partnership and parenting. The benefits further extending class advantages are identifiable in the intensification of transnational family practices following planned same-sex parenthood. These not only transform and strengthen the intimacies of CEE LGB migrants with their families-of-origin, but they also contribute to shifting assumptions of ‘normal’ familyhood, particularly in relation to technology-assisted reproduction, social parenthood and the nurturer roles.
