Employment Based Greencard

Here is my timeline:

EB1C category filed at NSC

9/12/2016 - I-140 submitted
9/19/2016 - received receipt for 1-140
10/12/2016 - I-140 got approved
12/02/2016 - filed I-765 and I-485 together
12/06/2016 - received receipt for for I-485, I-765
1/19/2017 - received notice for biometric
1/25/2017 - received EAD/AP combo card for my son
2/1/2017 - biometrics completed for all
2/18/2017 - received EAD/AP combo card for myself
3/2/2017 - received EAD/AP combo card for my wife

Status of I-485 remained as " Fingerprint fee was received" for two of us and "Case was received" for my son, since Dec 2nd.

I think I am still within the timeline and hope this info helps other EB1C/NSC filers from the month of Dec'16.
