This chapter proposes a divorce between migration and culture. The relationship between migration and culture constitutes an epistemic marriage, within the study of human migration across national borders that has continued for over a hundred years. The proposal of a divorce proceeds through the articulation of a new analytical category—a new couple: the mixed Migration-Mobility couple. This couple's existence challenges the assumptions around the host country evident in social psychological acculturation studies. Within acculturation studies, this couple exists below the radar both as an analytical category and a policy category. Yet, this ordinary couple, whether legally married or co-habiting, presents the possibility to reflexively interrogate many of the central assumptions and allegiances of contemporary migration studies. Such as the maintenance of a series of binaries between migrant/non-migrant, between the national/transnational, between stasis/mobility and critically between the public and migrant. This couple have an avant-garde potential to reflexively ask, within migration studies, what epistemic, practical and state-centric purposes do these binaries serve? The chapter first reviews the epistemic assumptions of acculturation studies and the rise of public attitude formation. It then presents a dialogical analysis of two interviews with non-migrants in intimate relationships with migrants. To reveal the potential of novel categories the chapter explores their positions on current and future migrations and what category-use can reveal for the design of migration research. Finally, the chapter proposes that future theories of migration require a willingness to abandon the sedentary bias in acculturation studies. Adopting the new category of the mixed migration-mobility couple allows future possible migration studies which are reflexively aware of the extent to which acculturation studies assume a public in the sense of a rational observer who is assumed to take a protectionist attitude to migration, rather than being in an intimate mutual relationship with the migrant.
