I-130 Approval Questions

Hi Guys!

I’m Canadian, my hubby is American. Our I-130 was just approved and I’m waiting to hear from NVC.

I’m most concerned about the interview process. Can someone PLEASE give me a list of what I need to know? I’m so so concerned ugh.

I can’t seem to find what kind of questions I’ll be asked. I’m not concerned about our relationship questions (we’ve been married 3+ years) but I’m more worried about questions I need to know regarding the history and ways of the USA.

Please give me any and all advice!
