The Department of State has once again released the demand data used to determine the July cut-off dates for the EB-2 and Eb-3 category. It is important to note that there are additional cases outside of these numbers that have not been counted (those who have already filed an I-485, for instance, are not included. Nether are any new cases that have been filed as of the cut-off date they have used (June 7, 2013) to determine the July Visa Bulletin).
Currently, the DOS lists the following demand in the EB-2 category (please note, this is cumulative demand as of January 1, 2013):
India: 43,100 cumulative demand
China: 5,100 cumulative demand
All Other: 200 cumulative demand
For the EB-3 category, the following is the demand (same dates):
All Other: 400
This will give you an idea as to why the July Visa Bulletin has the cut-off dates that it does.
