The interview was in February. Our interview time was at7:30am, but we got there around 5:30 or6am to try and avoid lines. There were already people lining up in front of the building. They have you line up in order and based on your reason for being there. This was the longest wait. Once they open the doors you go through security,pull a ticket and take a seat until they call your number.
It was really quick once we were called and had the actual interview. At most it took 5 minutes for us, but there were some people that were there way longer. I took a bunch of evidence to show, but they didnt ask for any of it. The questions they asked were how long we knew each other, what happened with my previous marriage,where we worked, and how we met. They approved him then, but wanted him to bring in a copy of his sons birth certificate so he did and he officially got approved two weeks later
