The visa bulletin for April 2011 was released today. Not much good news to report. Below is a copy of the pertinent message regarding F1 retrogression.
D. RETROGRESSION OF FAMILY PREFERENCE CUT-OFF DATES
Continued heavy applicant demand for numbers in the Family First (F1) preference category has required the retrogression of the Worldwide, China-mainland born, and India cut-off date for the month of April.
Further retrogressions cannot be ruled out should demand continue at the current levels for some categories and countries.
