It was actually pretty cool. Officer asked us to take oath which we did.Can you please share your interview experience?
He asked my father his name, date of birth, his current address. How many times he came to USA before, has he ever overstayed his visa or ever been deported, has he ever been convicted, member of communist party blah blah. He asked me where I work, why I have changed my last job, how many kids I have. He only asked for our passports and mine naturalization certificate and nothing else though we got two RFE-s. He also asked if I have aplied for my mother and when is her interview scheduled.
He asked for our I-130 NOA and I gave him both NOA and approved I-130 letter and he said " oh !..it has been approved already"..then after few more check marks in his file, he said
"good news" and finished his paper works and escorted us where we were
given a formal approval letter and told we will get card in next 10 days. I just got LUD as "card has been ordered"..
