I had my interview in Las Vegas today. I was expecting a combo interview, since I am applying on the 3 year rule and took a stack of documents with me. However, it was all very smooth, passed the civics and English test and we chatted a bit about my marriage and life here, and that was it. I got the paper saying I was recommended for approval and to wait for notice of the oath ceremony, which he said is likely to be in about a month, but maybe sooner. I'm a bit confused as nothing was really said about the 751, but hey, I'll take it! Just the oath ceremony now and this long journey comes to an end.
