This paper examines how visa policy affects international student migration. Using administrative data oncommunity colleges in Canada, we evaluate a reform that introduced a new visa stream - the Student PartnersProgram (SPP) - with shorter processing times and higher approval rates for student visa applicants able todemonstrate that they have the financial resources and language skills to succeed academically. Using a tripledifference estimator, we find that SPP increased student migration from treated countries by 33% relative to whatwould have occurred without the reform. In line with our theoretical model, we further show that SPP had a largeand positive effect on international enrollment only in countries where migration fraud was a major concern, andthat higher enrollment was driven by an increase in both the approval rate and the volume of applications to studyat treated institutions. We also leverage the SPP reform to investigate potential crowding-out effects. While wefind no evidence that the enrollment of international students took place at the expense of domestic students, ourresults indicate that the recruitment of students from countries eligible to SPP had a crowding-in effect on noneligible foreign students.
