MY SPONSOR IS MY MOTHER AND I HAVE MENTIONED THE SAME IN MY DS-160 FORM.SO I WANT TO KNOW IF THIS WILL BE A PROBLEM IN THE VISA INTERVIEW. WHAT SHOULD I TELL IF THE VO ASKS WHY IS IT MENTIONED THAT YOUR FATHER IS THE SPONSOR. I HAVE ALREADY PAID MY SEVIS FEE. PLEASE LET ME KNOW AS SOON AS POSSIBLE.
