Me and my wife had our AOS interview today and it was quick and painless. We got there early and were allowed in early. The adjudicator called us in and begin going through the normal application questions. Then we provided our proof of relationship and we explained a few trips we went on and then it was done. We were provided unofficial approval right at the interview and later this evening we are now at the green card is processing. So glad to have finished this process looking forward to not have to think about USCIS for at least 2 years.
