Like many others we have been waiting for our AOS application to be approved for over 2 years. But the strange thing is, I did get an EAD approved but they never called me in for fingerprinting and Biometrics. I know I had to do the non-immigration "registration" that was initiated a few years ago and they had taken my fingerprints and biometrics, is that why they didn't call me in again? since they already have it?
