Our appointment was at 8:40 am. They called us at 10am. We left at 10:45. The interview was about 30 mins. The female officer asked when and how we met, how the relationship developed, who proposed and where. She asked about the wedding and how many people. She asked K2 Child (10) how she liked California. Then then asked if there were any changes to the answers to the questions on the I 485. She asked for vaccination records, looked at our photos and some photos in an album from our wedding. She then said I will approve you now and had my wife and her daughter sign a paper. She said you should get your cards in the mail within 90 days. She would not give a specific time frame. They arrived 6 days later. We had the interview in San Bernardino.
