big big bless! There were many RFEs on birth certificate in the last couple of months, and if it is this, you only need to resubmit it again. 485 RFE is easy, and getting an RFE means that they touched your case, and you will get yours soon! Big Bless!
真心祝福! We've waited 13 years (Eb3 PD 2/2006), both hold US master degree, but unfortunately our employers only filed EB3 no exception, right now they even stop sponsoring GC. Sometimes, I am thinking if it is worth.
