Adjustment of Status - I-485

Hello my interview was at the Norfolk VA office on May 2. The interview went well and the officer said she would recommend us for approval however she kept saying that she needs to first find the paperwork with all my DACA documents they have since they should be in that file. She kept saying it was weird that it wasn't in the file. She mentioned that the A number immigration gives is like a SSN , you only get one . So then I told her that all of my DACA documents are under one A number but my application for the green card had a different A number . She looked at it and she said I was right so that she first needed to get the other file for DACA and then once she gets it she will recommend for approval. She said she has to order that file from where they keep all of these files and it will take longer than just the two weeks she early said it would take for me to get the approval. Has anybody gone through the same and do you know how long this can take? She gave me a piece of paper saying that they need to review my documents and then she wrote at the bottom "getting other A file. She did go ahead and explain how to the the condition out of my GC once I get it since I will get the two year one . She also said my GC will have the A number I have under DACA since I got that A number first. She made copies of all my DACA approval and renewal letters and took my I-94 as well. I'm just wondering how long this will take now ???
