U.S. Citizenship and Immigration Services (USCIS) has advised that, beginning with the November 2015 Department of State (DOS) Visa Bulletin, if it determines that there are more immigrant visas available for a fiscal year than there are known applicants for such visas, it will state on www.uscis.gov/visabulletininfo that applicants may use the “Dates for Filing Visa Applications” chart. Unless otherwise stated on USCIS’ website, the “Application Final Action Date” chart will be used to determine when individuals may file their adjustment of status applications.
USCIS further advises that it anticipates making this determination each month and posting the relevant chart on its website within one week of DOS’ publication of the Visa Bulletin.
