quadraphonics:
Thanks for the informative reference, but it was published in 2002 and most recent data mentioned in it that I found was:
“In April 1999, 27 percent of doctorate-holders in S&E in the United States were foreign born.”
The following is a more recent report, from a more authoritative source, but it also contains some 5 year data old. Things are changing very rapidly*
A few quotes from
Physics Today, page 30, March 2005 issue:
(1) "From 1994 to 1998 the number of Chinese, South Korean and Taiwnese students who chose to pursue Ph.Ds in their own countries nearly doubled... and those coming from there to US dropped 19%..." {Billy T insert: If more recent data were available, it would be much worse. - The US "terror fear" immigration policy has made the net influx near zero, if not negative. Korean IT workers now in US on work permits, must wait 7 years before they can apply to become US citizens. Many advanced degree foreign students are having difficulty to avoid deportation. US policy tryng to keep terrorist out is IMHO very crude, non selective, and counter productive.}*
(2) "The ratio of college undergraduates degrees in natural sciences is 5.7 per 100 students in the US .... "Taiwan and South Korea each award about 11 per 100." {Billy T insert: For several other countries listed the ratio ranges between 8 to 13.}
(3) Between 1988 to 2001, East Asian papers in science and engineering have increased by 492% while US production has actually decreased slightly!
(4) From 1980 to 2001 the US share of worldwide high-tech exports fell from 31% to 18% and China and South Korea's share climbed from 7 to 25% {Billy T insert: I think
in his important area, China has already passed the US, but US has a clear lead in Rock Concerts, NFL football game contribution to GDP, Hollywood Movies, and other “entertainment items” that have no lasting value.

*China has recently announced a program to make 50 educational centers equal or superior to Harvard. They will be staffed / lead by many first-rate imported western-world professors, now being “bought” by offering them salary increases. A large budget has been provided to the new department in charge of this. The article I read named three US professors, from Harvard, Princeton and MIT. Two of 3 had Chinese sounding names and all three were stated to be internationally recognized experts in their fields. - I posted a summary of that article in some thread about a month ago, but can not find it now to repost. - (Not this thread as I have just looked at the last 17 pages for it.)
The other point in article that impressed me relates to item (4) above and the low cost of construction in China: These centers, in new buildings, fully equipped with the latest research instruments, will cost less than half what they would if built and equipped in the US. It is true (I think) that the US still has the lead in scientific research in many areas, but the trends look like this will change in about 5 years. (Especially if the dollar has collapsed and western world is in a depression, with no money to support research and US lacking even money to pay Baby Boomers their social security, except with inflation-producing “printing press dollars.”)
Thus, IMHO, it is highly likely that the western world will soon experience a "brain drain" to China. Compounding this problem is the following fact, quoted from the very biref "Conculsion & Summary" section of quadraphonics' reference:
"The age structure of the U.S. S&E labor force is likely to produce several major changes in the S&E labor market over the next decade. The number of individuals with S&E degrees reaching traditional retirement ages is expected to triple. "
