Hello,
I wanted to thank everyone in this forum, and moderators in particular for this amazing resource. I learned a lot here, and it is very supportive to see people going through the same situation.
I know that many people are initiating congressional/senator inquiries and I wanted to share my experience - I contacted one senator by email and phone (twice) and got no response in 8 days. My lawyer said that I may contact another senator (in case their office is less busy), and miraculously they responded in two hours. Knowing time is running out, maybe it will be of use for people who have no response from senators.
About my case: I am from Boston (Revere), my interview did not get waived and not yet scheduled. My number became current in April, me and my husband applied then. Biometrics done at 6/1 and 6/2, EAD/AP approved 7/29, no news since. Lawyer requested expedited processing ~10 days ago, called USCIS today, and they said interview may be scheduled within 10 days (they read the response to request but reception was bad I barely got anything).
Our case might take longer than others in Boston office because our wedding was between winning lottery and application, and because of my background check (I am russian and work on one of areas that trigger administrative processing).
