Employment Based Greencard

Hi,
I would like to share my timeline and interview experience for my case EB2 - ROW (Europe), and I hope it's useful for some of you:

03/30/18 PERM Approval DoL
05/07/18 Receipt of I-140/ I-765/ I-131/ I-485 (at Nebraska Service Center)
05/10/18 Approval I-140 (Premium Processing)
06/04/18 Biometrics
06/19/18 Transfer to Processing Center
07/06/18 Approval I-131
07/12/18 Receipt of EAD/AP Combo Card in the mailbox
07/23/18 Notification - Ready to schedule the interview
08/28/18 Interview at USCIS Detroit

Interview:
IO was very professional, and the interview lasted for around 35 min. IO asked for identification (passport, driver’s license, and EAD combo card), originals of birth certificate, marriage certificate, EVL. She didn't want any copies of my documents. She asked for my most recent residencies in the U.S. and in Europe, and I had to briefly explain my professional and educational vita (What?, When?, Where?). She asked some basic questions (e.g., SSN, wedding date/place, kids names/birth days, parents names/birth days). Then we went through all I-485 Yes/No questions. My mandatory military service (both of myself and also of my father) was briefly discussed, as I had indicated this in the I-485 already. I explained my role/functions in the military, and she took notes. At the end, she explained that nearly all Visa categories are in retrogression at this point. When I asked about a potential approval at the beginning of the new fiscal year in October, she was very cautious and basically stated to wait and see. Shortly after the interview, my case was placed in the "interview completed, your case must be reviewed" status.

Good luck to everyone, I wish you all the best!
