There is now a large literature discussing how mobilities are part of contemporary everyday power geometries and is a resource to which people have unequal access. This body of work has, thus, valorised mobility as a desirable good. Why some people choose immobility and what has to be mobilised to enable this immobility has received much less attention. This paper draws on interviews with international distance education students in Namibia and Zimbabwe studying at the University of South Africa (UNISA) to explore the spatio-temporal underpinnings to why students choose to remain at home while studying abroad and how this is arranged. It outlines the infrastructures of reach that enable student immobility and how their incomplete nature means that students have to rely on extensive systems of mobilities of other people and objects to ensure that their study progresses without their own educational mobility. In doing so we move away from considering immobility as a result of limited access to mobility. Instead, we set out a new research agenda on why and how the infrastructures of immobilities are important in mobility research.
