We had a Labor certification case filed for an IT professional. The requirements were Bachelor's degree and 5 years of experience. We filed I-140 under EB-2 category. After approximately 8 months, USCIS sent us an RFE saying Bachelor's plus five years would not qualify under EB2 unless the experience required is progressive in nature. We knew that USCIS was wrong under the circumstances of the case, but an argument with the government was unnecessary because the EB-3 priority dates were then current.
USCIS confirmed that all I-140 petitions filed concurrently with an I-485 application for adjustment of status are to be filed with the Dallas Lockbox, unless the I-140 is accompanied by a request for premium processing, Form I-907. Concurrently filed applications that include a Form I-907 attached to the I-140 should be filed with the NSC or TSC, depending on the location of the petitioner.
