Hello,
A few nights ago I was sitting in my bed and watching youtube when I came across an interesting channel. It pertains to visa officers. This in particular one I am pasting worked as an officer for like 20 years IIRC. https://www.youtube.com/watch?v=VwyHGb-oc64&t=3309s
What I am getting at is these people are trained professionals and know how to ask questions. So if you versed back exactly what the paper says they are going to want more detail. Being evasive isn't going to work. Whatever you initially told them you will likely want to stick to IMO. I haven't looked into the particulars of this case but I will say this: I petitioned for my wife then fiance about 12 years ago and filed a I-601(over stay). To prove hardship was extremely difficult, and looking back at it I probably got lucky winning the waiver. These officers are giving a lot of power, if I were you I would try to control the narrative of the interview to the best of your ability without over speaking and by sounding authentic. You're going have to sell yourself as you are your only advocate here. Make sure you make your intent of your initial visit known. Which was for "tourist" purposes (visiting family, sight seeing, etc.)
