need some advice for my wife's interview

[tway22 0]

Any advice would be greatly appreciated. My wife's interview is coming up in a week. I am getting nervous by the second. Our interview for K-1 failed last year. They said it was a sham because we haven't met each other very long before I propose to my wife. My wife kinda screwed up during that interview, but I don't think it would have made a difference. The said we met May 28th instead of May 24th. I propose to her on the 28th. I knew after meeting her and hanging out with her the first day that I wanted her to be my wife. Now, if she is asked that question again, does she stick with what she said during the K-1 interview or should she tell them May 24th. My biggest concern is that they have records of what she said during the K-1 and will asked her during the CR-1 interview. It's only a few days extra that we gain but is it advisable to tell her to use the actual date instead? I think our case should be stronger since I have been back to see her a total of 4 times since we got engaged. But you never know with these people. Thanks for your help. Hope I didn't confuse anyone.
