CCB

I use my married name in all forms including I-693. All my documents were still in my maiden name and once I received my EAD card with my married name I used it to change my name in my CA driver license. My maiden name is still on my passport.

Have you called and ask to speak to a tier 2 representative? You can also make an infopass appointment at your local office. Some people are not approve at the interview and have to wait longer for their approval, so maybe you should try to get your EAD just in case.

I was really bored and I had nothing to do, so for my office I checked the profile of the people that got approved recently and went to their posts to see if they have a signature with their timeline...there are not many people from my office, but I saw that it took about a month to received their appointment notice after testing and interview update. Also, the appointment was set for a month after they received their notice...if you are that bored you can do the same with your office
