Every fiscal year (October 1st – September 30th), approximately 140,000 qualified applicants (principals and their dependents) receive employment-based immigrant visas under the provisions of US immigration law. This number is roughly divided among the preference categories as follows:
EB-1: 40,000 or 28.6%
EB-2: 40,000 or 28.6%
EB-3: 40,000 or 28.6%
EB-4: 9,940 or 7.1%
EB-5: 9,940 or 7.1%
If the quota from a category is not filled, it is transferred to another category. You can visit Travel.State.Gov to review The Visa Bulletin.
