I called NSC yesterday using PoJ method trying to verify if they indeed have connected my cases, and found out my 485 case still shows Eb2/second preference category. I then mentioned I have an approved EB1, and it took a while for the IO to find the EB1 through my A #. The IO also mentioned it seems that the congressional unit is working on it, as they have requested for my file. But he also told me my case hasn't been assigned yet.
I am very confused about the whole situation. It seems that the IO at congressional unit did nothing to my case and to resolve the issue, except for issuing an request for my file. Do you think he has already got my file? What will he do with my file, since I guess he could just correct CIS record and relink my cases electronically? Also, what is the exactly meaning of "Case has been ordered to review"? Does congressional unit has the right to adjudicating a 485 case? Your suggestions and comments are highly appreciated, and I need some analysis and advice on what to do.
