AC-21 does not require approved I-140. The fear is employer may revoke your I-140 before its approval. That is the reason sb_tiger is telling not to change the Job.Originally posted by sb_tiger
No. AC21 requires 140 approved and 485 pending > 180 days. However he can change jobs if his old employer continues to support 140- will not withdraw it and respond to RFEs.
