In recent years, especially during the l960s, there was much discussion about “the brain drain (排干, 流失),” which dealt with the problem of students and learned people who left their own countries for other countries that offered better chances for study, research, and employment.For example, according to a report from U.N., between 1962 and l966 more than 50 percent of all engineering graduates of Iran and 14 percent of Iranian scientists left their country for work abroad.Over 30 percent of Chilean engineers and 15 percent of Turkish physicians also went to work in other countries.Probably the greatest brain drain occurred among young scientists who had gone abroad to study.Many of them had planned to return to their countries to teach but chose to remain in more industrialized nations where they were able to continue their work and their research in fields in which there were no job possibilities at home.The countries that attracted most of these scientists were the United States, Great Britain, Germany, France, Canada, and Australia.

  Recent studies show that the brain drain to the United States may be decreasing.Many foreign scientists are going home again, and in some cases American scientists are leaving the United States for employment in other countries.The main reasons are that good jobs are becoming fewer here, money for national research has been sharply cut, and university fellowships reduced too.However, in the field of medicine the drain to the United States still goes on.Today more than one of every five American doctors is foreign - born, and several thousand foreign doctors immigrate to the United States each year.Over eighty countries have asked the State Department to send students who are skilled in important fields such as medicine back home when their study programs are over.
