回複：I-485 Questions: Second Fingerprint and "Earlier Approval"

"Tian You"We have the same situation as yours. We got 2nd FP notice and also had the same notice email from USCIS today. We called. The customer service told us there is a welcome package to us. But I am confused. If our 485 cases were approved, why should we do 2nd FP? "Tian You" Please update what you got after you receive your letter. I really appreciate!
