Visa policies in the United States restrict job opportunities and job mobility for U.S.‐trained PhDs who hold a temporary visa, a group that accounts for 40 percent of newly graduated PhDs in science and engineering. The Chinese Student Protection Act of 1992 (CSPA) allowed Chinese students to be eligible for permanent residence in the United States. Many CSPA beneficiaries, Chinese students who became permanent residents, did not pursue postdoctoral training and instead entered the public or private sector directly. This supply shift increased the relative wage of native postdocs to non‐postdocs. Four to eight years after graduation, CSPA beneficiaries earned 9 percent more than the comparison group, were less likely to work in academia, published fewer research articles, and produced more patents.
