This document discusses the challenges facing the EU in attracting and retaining high-quality researchers and scientists. It notes that while science is becoming more globalized, the economic benefits of research are measured locally. It also discusses Germany's inconsistent policies around restricting immigration of high-qualified researchers, and argues that facilitating the immigration of researchers should be a priority for the EU. Finally, it examines the mobility of researchers as dependent on both individual desires and circumstances as well as policies in home and destination countries.
