Employers who wish to sponsor H-1B workers for Fiscal Year 2016 can begin filing petitions on April 1, 2015 for a start date of October 1, 2015. The H-1B visa is used by businesses who wish to employ foreign nationals to work in a specialty occupation requiring theoretical or technical expertise. For FY 2016, cases will be considered accepted on the date that U.S. Citizenship and Immigration Services (USCIS) takes possession of the petition, not on the date it was postmarked.
