04/04/2012: Gosh, March 23, 2012 Was a Ominous Date for Indian & Chinese EB-2 485 Applicants or Waiters Whose Priority Dates Are Either 08/15/2007 or Later Date Regardless of April 2012 Visa Bulletin!
According to the AILA, State Department Visa Office stated that effective 03/23/2012, no EB-2 visas for Chinese or Indians have been authorized if the priority date is at least 08/15/2007 or later dates.
Next question is what then happens with the immigrant visa applicants whose applications have been pending pursuant to the April 2012 Visa Bulletin. Apparently, visa numbers have already been allocated for such cases. Accordingly the visa posts will continue to process and issue immigrant visas to such applicants. What about the new EB-485 applications or pending I-485 applications whose visa numbers are current for their priority dates in April 2012 Visa Bulletin? Apparently the USCIS will contine to receive and process EB-485 applications for those whose priority dates are within the cut-off dates in the April 2012 Visa Bulletin. However, their EB-485 cases with priority dates of 08/15/2007 or later dates will be held by the State Department Visa Office as pending files until new visas are available beginning from October 1, 2012, FY-2013. OUCH!!!
SO does this means that all applied before 03/23/2012 is allocated a visa Number and will be Issued GC!!!
