Hi everyone. Does anyone know which kinds of questions in the interview day will be asked for a widow who had her approved I 130 converted into an approved I 360 self petition?!. I heard the interview officer will ask questions from the forms were submitted at USCIS, but after my husband passed away, NVC converted those forms to an i 360 and they will send the approved I 360 to the US embassy for the interview, so where will the officer get the questions from? From the I130 and i 130a forms before they were converted to an I 360 or from the I 360 form that was converted by NVC and sent to the US embassy?! Please help me figure out what kinds of questions a widow will be asked at the interview day. I searched a lot in the Internet but i never find any website that talks about kinds of questions will be asked to widows who applied for GC.
