Hi
@HappyDV2021, sure.
Our interview was scheduled on 02/03/2021 in the New York USCIS office. My wife and I were already on our way to the interview when my wife got a call from the USCIS officer stating that her interview will be rescheduled because of some hiccups caused by the 2-day snowstorm just before. Since we were already on our way and I (the main applicant) didn't get any calls we decided to get there and find out what's happening (it's also stated on the interview appointment letter that failure to attend the interview will result in automatic case denial, so we wanted to double check the rescheduling in person).
We arrived to the USCIS office right on time and registered with our appointment letters (we tried to ask about the rescheduling at each checkpoint but we were told to go further). We received a ticket for the line and waited for someone to call us in. Eventually, after about 1h of waiting we were invited to the interview. The interview itself was nothing special – we took an oath and the officer asked us some basic questions from our I-485 forms (biographic information and all the "NO" questions from the end of the form). Then he also updated our address (we moved right after we sent the I-485 and we sent the Change of Address request, but apparently it didn't work as well as expected) and told us that he still needed to do some paperwork, but overall everything looked good, so we can expect to get the status updates soon.
Overall, it looked much more relaxed compared to the regular visa interview. If you have any other specific questions feel free to ask.
