Finally had the GC interview today at the SF office. Whole process took about 10 months since application was submitted in March of 2017.
Interview went okay and the questions were definitely rapid fire type questions:
"Where'd you meet?"
"How'd you meet?"
"Have you met the parents, and have the parents met each other?"
It was definitely nerve-racking in the beginning when she was asking about my passport and why the surname didn't match my last name on my current DACA EAD. Once we cleared that tiny issue out with her, she was able to be more opened and friendly to whatever else we answered and provided. It seemed like the interviewing officer was checking to see how my wife and I handled some of the the questions she asked our way. Quick answers would have seemed too "rehearsed", so we definitely had mini-conversations while we came up with the correct answers. All in all, it felt like the officer was more friendly towards the end of the interview once my wife took the lead on a few answers.
As for evidence, we provided our wedding pictures, current bank statements, utility bills, and honeymoon tickets at the interview which led to her approving my 485 on the spot. USCIS case tracking hasn't shown my 2-year GC as approved yet, so I wasn't sure how long before the system updates. Has anyone else faced this beforee if/when they were approved on the spot?
