SIDEBAR: Foreign Graduate Students: Stayers and Leavers
Of foreign students who graduated with science or engineering doctorates in 1984, fewer than half remained in the United States in 1992  (Finn et al. 1995). About 41-42 percent of students on temporary visas (48-49 percent of those on all visas) were still working in the United States 8 years after earning their doctorates. The study also found that "stay rates" varied by
- field-engineering had the most stayers and social and life sciences the most leavers.
- country of origin-many students from India, the People's Republic of China, and Iran stayed, and many from Korea, Japan, and Brazil, left.
They found no significant variation by
- salary or
- prestige of departments where students earned doctorates.
 The study used social security numbers to match doctoral graduates from abroad with U.S. earnings. If the Social Security Administration did not find evidence of an individual's having earned at least $5,000 in employment covered by social security, the researchers classified him or her as a "leaver." They made adjustments, however, to take into account individuals working in jobs not covered by social security.
