you cannot get around, still have to file 140!!

Schedule A, Group II is not an immigrant visa classification. It is only a waiver of the alien employment certification requirement certification requirement imposed on most employment-based second preference and third preference immigrants. Any Schedule A, Group II request must be filed with the BCIS with an immigrant visa petition under one of those two classifications.
