Congratulations!!! I’m so happy for you!
I think I interviewed at the Las Vegas office the same day you were. Same great experience! The security guard at the front would not let my husband in, but then again, I did not press it and so he went to wait in the car for me. And he did not have to wait for long. I was done in something like 11 minutes, lol. The best, easiest interview I could ever ask for. I brought a very large folder with lots of evidence that I spent a while preparing… in the end, was not asked for a single thing (just my driver’s license and green card). The officer was super nice, asked 6 simple questions, did the English test, asked a few yes/no questions, a couple of very basic questions about my marriage, and she approved me at the end of the interview.
I also got the date of the oath ceremony the same day I finished the interview. So relieved to be almost done with my immigration journey! A nice early Christmas present
