The Department of State published its Visa Bulletin for October 2016. The Visa Bulletin is a monthly report on visa availability. USCIS has determined that for the month of October 2016, applicants for all family-sponsored and employment-based preferences may use the Dates for Filing Visa Applications chart.
Congress annually sets the numbers of immigrant visas that may be issued for the family-sponsored and employment-based immigrant preference categories. If you are a prospective immigrant in any of these categories, the Visa Bulletin shows when a visa is available to you based on your priority date.
