Yes, USCIS sometimes conducts field investigations into the bona-fide nature of the marriage, among other things. It is very possible that he was an officer checking up on you, but there is no telling for certain who the man was. Most women who are at home alone would be scared of opening the door to a stranger at that time in the evening, especially in plain clothes. If I were in your position, I would wait with your wife and see if the man returns tomorrow during the day and have him see the two of you there together. That said, you should go on with your normal everyday life, including your nighttime work schedule.
Best of luck to you.

We have definitely had clients that are visited by an investigative team at odd hours. The appearance of this person sounds suspect, and I would advise you to ask to see credentials, such as a badge or ID card. You can also call the police so they can investigate who the person is who is coming to your door. If you are in a legitimate, good faith marriage, do not worry about the investigation. They may be intimidating, but with good advice from an attorney and by living honestly, you will have everything you need to pass the investigation and nothing to hide.

Yes, USCIS continues to conduct field investigations. However, you probably should not just assume that this person is from USCIS and allow them to enter your home. If you are concerned about the individual who is knocking at your door, call the police department or neighborhood constable if you have one.
