I had my interview today in San Fernando Valley FO. It was such an easy and pleasant experience, I didn't expect that! The entire interview felt rather a conversation. It lasted only 20 minutes. I answered 6 civic questions and that was enough. Then reading and writing test. Then the officer went through my application, asking to confirm my work and travel history (btw, one of my trips was 5,5 months long, no problems with that). Then he asked about my traffic ticket. I said that I had paid the fine and was lucky to avoid a point and he laughed. No proof was asked. The only documents he asked for were ID, Green Card, passports and an interview invitation, nothing else. I brought my application but wasn't allowed to use it during the interview, however my friend in LA FO was allowed to use his. So, just in case, you can bring the application and ask for permission to use it.
I'm changing my name, so same day Oath ceremony wasn't an option for me. Now I have to wait for an oath invitation in mail. Does anyone know how long does it take when changing the name?
