Yeah, I can't identify a point that he will be beneficial.In my opinion, if you cannot actually identify a way in which the attorney will be beneficial /needed for your case, why bother bringing him? He has already given you bad information about what you need to bring, which makes me think he might complicate things. He clearly is not familiar with DV based interviews. (Surely the service paid for by your company is for employment based AOS?) If best case is he says and does nothing... what’s the point?
Yes, it is employment based AOS.
