Possible EB-2 Priority Date Movement in the Coming Months
Cite as "AILA InfoNet Doc. No. 11040563 (posted Apr. 5, 2011)"
Following-up on his earlier observations on EB-1 demand and "spill-down" to
EB-2 reported on InfoNet on March 29, 2011 (InfoNet Doc. No. 11032960),
Charlie Oppenheim discussed scenarios for EB-2 movement in the coming months
. In preparation of the May 2011 Visa Bulletin, DOS will consider the
approximately 12,000 unused EB-1 numbers that will "spill-down" to EB-2, EB-
2 demand and possible unused numbers, and will consult with USCIS on its
processing potential. A quick look by DOS at this point indicates that there
is the possibility for greater advancement of the India EB-2 category than
had earlier been thought. Doing so will give DOS better visibility into EB-3
upgrade demand in the pipeline, and will better ensure that all visas
allowed annually are used. However, a rapid advance could spur a surge in
demand that could impact the cut-off dates later in the year. The May Visa
Bulletin, generally issued mid-April, will contain a discussion of visa
availability projections for the remainder of the year.
