Sure, our field office was the Boston Field Office, interview lasted about 25 minutes in total. They interviewed my US Citizen spouse first then I was asked to join the interview. The interviewer asked me our full names, husband's date of birth, if he has any siblings, asked me if I had ever met his family, when last I entered the US (never traveled out since I was brought here as a child). I was also asked details about our apartment, asked how I met my husband, asked whether my husband has ever met my parents and siblings, I was asked their names, I was asked if we had ever taken any trips together. The interviewer asked us to leave some pictures from our photo album and also provide any documents that shows comingling. We had bills with our names on them as well as insurance documents. We were thankfully approved on the spot.
