Plan getting married

hello to everyone ,is there any possible to get denied  the interview to having  legal capacity of marriage?
is there any denied after the interview even both of us are  single?

We went to the US Embassy with my divorce decree and some of the letters we wrote to each other to show we were in constant contact for two years.  The official at the embassy gave us my capacity  to marry paperwork in 5 minutes,his only comment was that he also liked the Moody Blues, as I was wearing my In Search of the Lost Chord t-shirt.
