Is it always USCIS update about case is ready to be schedule ??

[Aryan16586]

My PD is April 4 th Marriege based GC file.
Sent out 485,130,131,765 on 1 st April
Received by USCIs on 4th April 2016
Biometric on 5/12/2016
Service request made on 6/27/2016
EAD and AP status got approved on 6/29/2016
Received EAD and AP card on 7/7/2016

Question is my 485 online case status still same like "fingerprint fees was received on 8th April"
So is it always USCIS change status before they schedule interview or they may not change and just send a letter with scheduled interview date?? Because I m following with few falks who are Maryland filers but even though tgeir PD is later den mine,their status has changed to "ready for the schedule I interview or some got already scheduled interview...so I m worried why my status s not changed..is there any thing we can do about it except waiting ??
Feedback is accepatable and appreciated please suggest me
Thank you and good luck to all of us

USCIS is so annoying with updating their website. they may not update the website but delivered ur mail. just watch the mail box instead of the website because if u missed that appointment it will be hell to reopen the case. my friend got her letter less than 60 days after the work permit. they gave her 2 weeks notice.
