VISA RETROGRESSION OF MEXICO AND PHILIPPINES CUT-OFF DATES for JUNE 2015 VISA BULLETIN.
Family-sponsored Fourth preference: It has been necessary to slightly retrogress this cut-off date to March 1, 1997 in an attempt to hold number use within the annual limit.
Family-sponsored First preference: This cut-off date had been advanced very rapidly during the past year in an effort to generate sufficient demand to fully utilize all available numbers. The resulting increase in demand has required the retrogression of this cut-off date for the month of June, in an attempt to hold number use within the annual limit for this preference category.
Employment-based Third and Third Other Worker preference: Continued heavy applicant demand for numbers has required a second retrogression of these cut-off dates. Further corrective action cannot be ruled out.
