Did biometrics today - I had 2 appointments as I mentioned in my above comment, it went well (will go into detail due to the weird situation of having I765 filed online and seems separate processing)
USCIS ASC Alexandria (Virginia), super busy, first app was 1pm, arrived at 12:45. Huge line and wait, first lady checked my docs and sent me to second line, second line the employee reviewed my docs took my ID and stamped my appointment notices - both of them, giving me a number to wait for that number to be called then proceed to the worker to get my prints done etc. After almost 2hr wait (super busy), made it clear I had 2 appointments, she took 1 set of fingerprints but 2 pictures, 1 signature (assuming signature and prints just attached to both apps), after getting in car both I765 and I485 statuses updated to "Case Is Being Actively Reviewed By USCIS" (assuming normal/automatic after biometrics completed.
Fingers crossed for a speedy EAD approval
