We interviewed October 5, 2016 and we're told to wait. After 4 months, we were denied for "abandonment": because we did not reply to an RFE they said they sent to us - but we never received.
Later, a lawyer said that had we been using a lawyer, any correspondence to us would have also gone to his office - and we would have known about the RFE.
So, you can only wait ... there is nothing else you can do. I am guessing it is in background check, though somebody else might know better.
