Our interview was at 8 AM and we were out by 11:10. We reached there at 7:43 AM and went right in. The actual interview only lasted about 3 minutes. We are an interracial couple with a 14 year age difference (me being elder). We also eloped with only 2 friends at the wedding because we didn't think his parents would approve (we have since told them and they are cool). The interviewer didn't ask about either of these things. He only asked how we met (at work. My company sent me to train his team. When I returned to the US, he would message me with work questions and we would then start talking personally). We also have a 2 year old son and most of the questions were about him. The interviewer wanted to see pics of our wedding, pics of the 2 times I brought our son to India, and our son's birth certificate and passport (he was currently at the hotel with my husband's sister). My husband was then told he was approved. It was a great experience.
