回複：kua, did you receive I-485 receipt? Thanks.

Not yet, although my USCIS page indicates that on Aug 23rd, a notice was sent out describing how they will process the case (to my lawyer). Then the 485 page was updated on Aug 29th, but no new message was posted. I got all the receipt number from the back of my cashed check images posted online by my bank (Wells Fargo) on Aug 25.

I will keep you posted about the progress of our applications.
