The priority dates in the employment based 2nd preference category, also known as EB-2, moved up an entire year for China and India. Beginning on February 1st, 2012 USCIS will now accept I-485 applications for individuals in the EB-2 category from China or India with a priority date of 1/1/2010 or earlier. The January 2012 Visa Bulletin indicates that this month USCIS is working on applications filed on 1/1/2009 or earlier, which had a 9 month jump in the India/China EB-2 category from the December 2010 Visa Bulletin (which indicated USCIS was working on cases filed on 03/15/2008) .
The large jumps in the visa numbers indicate a large reduction in labor certifications during 2008 through 2010, which not surprisingly corresponds with the economic downturn.
Priority dates can retrogress so we recommend that anyone who is eligible to file does so as soon as an immigrant visa is available. If you need assistance, please contact an immigration lawyer.
