I had the same situation I do not think they can complete processing our applications in 6 months when we even had not clear eligibilty stage this is kind of first stage after on ip2you are Inland or Outland applicant?
I just call them and agent first told me that my back ground check in progress and then I ask regarding my eligibility and she mention that it is still progress. I do know what is going on they are still working on eligibility after 4 months. My AOR is 4th Oct 2018, is there any one who has same status?
