The brain drain: Old myths, new realities

OECD Observer article:

"The United States is the main pole of attraction for foreign skilled workers; 40% of its foreign-born adult population have tertiary level education. Since the early 1990s, some 900 000 highly skilled professionals, mainly IT workers, from India, China, Russia and a few OECD countries (including Canada, the UK and Germany) have migrated to the United States under the H1B temporary visa programme. The United States also takes in 32% of all foreign students studying in the OECD countries. Indeed, higher education is an important channel for US firms recruiting highly skilled migrants; some 25% of H1B visa holders in 1999 were previously students enrolled at US universities."
