Transnational mobility has become a ubiquitous phenomenon. Yet it is inherently transient and unstable. How then can we analyse it ethnographically? This special issue presents a number of methodological experiments that explore the interfaces between individuals migratory experiences that are always context specific and can never be fixed, and institutional, structural and historical forces that are themselves constantly changing. The articles respectively explore multi-scalar, tandem, multi-media, centripetal, and lateral ethnographies as new modes of field research, writing, and analysis.
