But researchers from EU keep on coming.

According to a European Commission (EC) report on the continuing transatlantic brain-drain reveals that U.S. universities and research jobs are attracting growing numbers of European Union researchers. The EC paper voiced concern that 75 percent of European Union countries-born U.S. doctorate recipients have no specific plans to return to the European Union (EU), and more and more are choosing to stay in the U.S. The most important reason keeping EU-born scientists and engineers abroad has been quality of work. Better prospects and projects and easier access to leading technologies were most often cited as reasons behind plans to work abroad.
