Online status was changing on time. Right now our status: interview completed and under review.

We were waiting for 1.5 hour and our interview was for 40 min.
Questions:
My husband: went through all information and Yes/No questions from I-485
Me(USC): All information from I-130. Questions about my previous marriage.
My husband: how he got here and when.
Both: how we met, when, where. When did we have second date, when we became boyfriend/girlfriend. When we moved together. Who proposed and when and where. When did we get married, where, did we have honeymoon. Questions about our kid, date of birth, name, place of birth.
After that she asked to give her evidence we brought:
Life insurance.
Medical insurance
Auto insurance
Rental insurance
Car lease

She was checking our affidavit of support, the one we sent in September last year. She said she has everything she needs. And I forgot to give her 2017 tax return. Now I am very worried about this.....

Also, she made 3 corrections on our I-485 application. 2 questions we answered incorrect, not sure how it happened. We were filing all papers with help of lawyer. Also, my name was incorrect. I asked her, if it's a really serious problem, but she said there is not too many people who have their application without mistakes. She said, do not worry about this....

So, now is again is waiting time, stressful, even more then before...
