This document summarizes a presentation about researching multilingually at borders. It discusses working and researching multilingually in Bulgaria and Romania, with a focus on the influence of EU borders on identities. Specifically, it examines how EU borders influence the identity of those on the "wrong" side, like in Moldova, Serbia, and Ukraine. The presentation also explores issues that arise when using more than one language in sociological or anthropological research, such as how researchers learn new languages for fieldwork and how to critically reflect on language use in the research process.
