Quotas and Quality: The Effect of H-1B Visa Restrictions on the Pool of Prospective Undergraduate Students from Abroad
研究发现2003年美国大幅削减H-1B签证数量后，国际申请者的SAT成绩下降约1.5%，高分学生减少，表明限制性移民政策会降低高能力国际学生赴美求学的意愿。
In October 2003, the United States drastically reduced the number of H-1B visas available for foreign-bornworkers. Such restrictions could make U.S. colleges less attractive to foreign students considering an American education as a pathway to U.S. employment. Citizens from five countries are de facto exempt from the visa restrictions, however. Our difference-indifference estimates show that restrictive immigration policy reduced SAT scores of international applicants by about 1.5% and decreased the number of SAT score reports sent by international students at the top quintile of the SAT score distribution. Restrictive immigration policy disproportionately discourages high-ability international students from pursuing education in the United States.
