Pjiang,
My current status is 485 pending as PD is not current, and 140 was approved long time ago.
I just noticed that my 140 approval notice does NOT have the A# (Alien number) shown in my 485 receipt. I checked with a few of my friends, and their 140 approval notice does show A#. In the meantime, my 485 receipt does not show my priority date either. My question is that will this be a problem? When my priority date becomes current, how does USCIS know that I am current since the 485 receipt does not show my priority date, and since my 140 approval notice does not have A#, I am NOT sure how they could link 140 case and 485 case together.
Thanks for your insights
