 In particular, one of the main factors inflating the number of student visas issued to students from China was that the visa issued was a single-entry visa valid for one year, so a student visiting family every year had to renew the visa.The United States and China switched to a 5-year validity multiple-entry visa in November 2014 and the corresponding reduction in the number of F-1 visas issued should therefore be seen in the statistics starting Fiscal Year 2016 (since the first multi-entry five-year validity visas will be issued in Fiscal Year 2015, there will be less need for visa renewal starting in Fiscal Year 2016).In the table below, the columns are arranged in decreasing order of F-1 visa usage in FY 2015.
