The interview was smooth. We answered a few questions about how we met and were married. I spoke, my husband filled in some. We ave been married for four years, my son was with us, and I am pregnant. We brought many thing they didn't ask to see. Dad will co-sponsor and submitted more documents on grandmother's health..she s living with us from US, and technically that is our proof of domicile (a bit different).
Awaiting finalization of AP (which he had for his B1 as well, it took 6 weeks, and we will see! Inshallah Khayr.
