The Department of State (DOS) posted the Visa Bulletin for May 2019, which provides the visa number availability for family-sponsored and employment-sponsored preference categories, as well as for the diversity visa lottery cut-offs. USCIS has not announced that in May 2019 it will accept adjustment of status applications based on the filing dates chart for family-based cases and the final action dates chart for employment-based cases.
The following information is the for the final action dates chart. The EB1 worldwide category is at March 1, 2018 and is at February 22, 2017 for China and India. The EB2 worldwide category remains current and for India is at April 16, 2009, and for China is at May 15, 2016. The EB3 worldwide category remains current and the EB3 category for China is at August 22, 2015, and at July 1, 2009, for India. This is unusual that the EB3 date for India is more current than the EB2 date, but it is not recommended that those from India attempt to downgrade their Form I-140 immigrant visa petitions to the EB3 category yet.
