When ask did anyone help you prepare for this interveiw?? I told her it should be Yes becuz your partner has to bring things for him to show at interview I think that's called helping So yes Am I right??

I'm no expert, but I would think yes. What wife isn't going to try to help her husband prepare for such an interview? "Don't forget to bring this document, and do you remember my mother's maiden name? Remember to tell them about . . . " Etc. I would call that helping and the important thing is to be honest, so I would say, yes.

My answer would be, yes my wife/husband/fiance and I went over all neccessary documents together and discussed the supporting evidence, other than that no one prepared me.
