Adjustment of Status - I-485

Hi everyone, i check this site everyday and learn a lot by reading your posts. I'm married to USC. we got married in AUG 5, 2015. We filled combo package at Chicago locker box on 8th of July 2016. It's been 64 days but still all case status is on Case Received on 8th of July. I'm wondering about my EAD. Getting good job offer's but can't work until i receive my EAD. Here is my timeline:

Jyly 7, 2016: - Sent package with I-765, I-485, I-131, I-130.

July 8, 2016: - Package received by USCIS

July 21, 2016: - Received I-797 for all applications

July 27, 2016: - Received notice for bio metrics scheduled on 2 Aug, 2016

Aug 2, 2016: - Bio-metrics done at Fairfax, VA

Sice then i have no update on EAD or anything else. We are from Virginia and all of my application numbers starts with MSC. I don't know exactly what that means. I have seen few post where they mentioned the query. I tried to raise query for my EAD update but it didn't let me do so. It says the application is withing processing time. Please help me with that. And also we don't know which service center or field office our case is in. Thanks to everyone for sharing there experience ere. It's really helpful.

Have a great day friends!
