The article deals with the analysis of specifics of researcher emigration from the post-socialist Central European countries to the USA in the context of the discussion on different approaches to the 'brain drain' phenomenon and its forms. The extent and structure of researcher migration from the Central European countries to the USA are compared to migration from the Western European countries using several data sets. The findings show among others that the intensity of researcher migration from the Central European countries to the USA was higher than from Western European countries in the early 1990s but it decreased significantly afterwards. Brain waste of highly qualified migrants from Central Europe persists.
