Experience with the I-485 Interview:

Arrive with spouse for the interview on the day, waited 30 minutes to go in but only ask me (Principal applicant) to go in because did not have my spouse file.

In and out of the interview within 10 minutes. Name and ID check, Yes/No Questions and for medical report (I-963). Did not ask for anything else. No approval on the spot, I guessed she wan't in great mood or felt the IO just want to get out of the office. Was told to hear from USCIS in 2 weeks (which didn't happen). I guessed it was retrogression then.

Update:

Made several calls to the USCIS hotline in Sept and Oct for my spouse pending case and the IO mentioned all normal and just wait.

Fast forward to 12/18/2018

Went for a 12/18/2018 infopass on the my spouse case which is stuck on status for 04/2018 Biometrics Completed. Had not receive interview notice.

The IO at the windows told me my spouse file is already in National Records Center (NRC), read carefully not NBC (National Benefits Center). She mumbled herself saying something like "a mistake" etc and apologetics and said she will request for my spouse file to be transferred back to SNA field office for processing. Does anyone has similar experience on this? I guessed if your case pending too long, go get an infopass to check, your pending I-485 might have been mishandled and sent to NRC for storage for good. So it's pretty unheard of but my spouse pending I-485 file was stored away in NRC. (That's NRC!, not NBC)

Other issues:

The category printed on my green card was wrong. Supposedly it should be E18 for EB1C Adjustment but instead I got one with E10 (Child of a priority worker). so you got to check if this info is also correct. (Rookie mistake?)
So need to file I-90 to get new green card and possibly an I-551 for now.

Booking your Infopass online will be a thing of the past beginning from Jan 2019 (sometimes in Jan, don't know the exact date). So you can't book your infopass yourself anymore, you have to get and convinced the IO on the phone to help you if he/she thinks you are worthy of an infopass at the local field office.

Overall Experience so far:

It's messy process as you can see from my experience full of simple and rookie mistakes everywhere and depending on the your "LUCK", I guessed.

So, good luck !
