Cite as “AILA InfoNet Doc. No. 12031639 (posted Mar. 16, 2012)”
On March 16, 2012, at the AILA Midwest Regional Conference in Chicago, Charlie Oppenheim, Chief, Visa Control and Reporting at DOS, informed participants that he will likely retrogress India and China-mainland born Employment-Based Second Preference priority dates to around August 2007, effective with either the May or June 2012 Visa Bulletin. He also advised that he projects that all EB-1 visas available in FY2012 will be used this year, resulting in no “spilldown” to EB-2.
