The AoS is a series of steps that have to happen, starting with submission of your I-485 package.
According to the spreadsheet you have completed the biometrics, so the next thing is the interview itself. Your cases is moving nicely. So it makes sense to keep the infopass and ask them when they will schedule your interview - it could well be in November - and you should push for that to avoid it clashing with the December date.
There are two other things your case needs:
The FO to request your file from KCC (you can phone KCC to ask if/when that happened, if not bring that up at the infopass).
The other thing is the background check. When you go for the infopass you can check that they have the background check.
With regards to the FO requesting the file from KCC I have a question.
I was told by the FO they are waiting on our file(s) from KCC, after the conversation with the FO I called KCC and they told me that the FO has not requested the file. Seems to be a disconnect, any experience with who to "believe"?
