Adjustment of Status - I-485

Hi All

I am very worried on my Green Card and hence decided to get some advice here.

I entered the country using a K1 visa and got married to a US citizen and after that applied for my EAD, Advance Parole and Adjustment of Status.

Receipt Date - Mar 6 2017

Field Office processing the application - Chicago

Bio-metrics - 14 Apr 2017

EAD & Advance Parole - June 2017 (combo card)

Till here all went as per schedule and we didn't face any issues. Now, its been over 13 months and we haven't heard back. By January of this year we started to get nervous. I called USCIS and placed a service request around Jan 16 2018. They told us we should hear back from them in next 2 weeks since their normal processing time is 8 months. I call after 2 weeks, they said, the maximum time for response on a service request is 30 days. However, our case is not outside of the processing time as they are currently processing for Feb 3rd week of 2017 (Feb 21 2017 was mentioned on the website). So, we decided to call once the date on the website changed. When they were processing for March 1st week (March 15th the dates changed on website) and we called them, they said our case is with an officer and we should hear back in a week. Its been 3 weeks and we haven't heard back. Today we check online. They have changed the way they give out statuses. They no longer give dates and only a processing time of 11 months to 29.5 months. When I asked them about all my previous correspondence, they said they only have this information that the processing time is now 11 months to 29.5 months and refuse to comment on anything else. The level 2 agents also say the same thing.

We haven't received any request for evidence or any other correspondence from them. Please advise on what we can do. We are very worried and no one us giving us any information. Has anyone else faced this? Does anyone know what is happening? Any information on this will be of great help.
