Thanks! We updated and uploaded it before the interview, but they didn't ask at the interview. They asked for original birth certificate, married certificate & police clearance and 1 passport size photo.
Yes, I was approved. Process went smoothly. They asked few basic question. Who is your petitioner? How did you met? do you have kids together? where is he live in US and what he so for living? illegal entry or overstayed in US? any criminal records? That's all. I would highly recommend to upload all tax and i-864 prior to interview.
