I had an appointment scheduled for 4:45am this morning at SFO and my wife's appointment was scheduled for 6:30am. We left Sacramento at 2am and were at the Global Entry office at SFO before 4am.

There was one woman outside the office waiting for her 4am appointment. She was taken in a few minutes early and was in and out within 10 minutes at the most. After that, both my wife and I were taken in together (there were two agents working at that time) and we were out in less than 10 minutes as well. There was no one else around after we left.

While in the interview, I asked about these overnight appointments and was told that not many people show up to them and things have been very quiet during the overnight hours. They said that some people don't realize that the times are military times and are showing up at 2pm when their appointment is at 2am and are getting turned away.

I am posting this for anyone who may need or want to get an interview quicker at SFO. If you are willing to take a chance and show up in the middle of the night and the current no-show trend continues, you may have a good chance of getting your interview done at that time. You can always call the office ahead of time and see what they say as well.
