I've not seen it happen yet, but if you're worried about this then you may have some issues to speak to an attorney about before going to USCIS for your interview. You can find an experienced immigration attorney near you at www.aila.com, the website for the American Immigration Lawyers Association. I would advise a consultation and, depending on your situation, hiring someone to accompany you to the interview.
