After submiting our I-129F application, I realized that my fiance's Letter of Intent to Marry said he was asking for a V-1 visa instead of a K-1! I'm not sure why or how that mistake happened, but it made me extremely nervous. So, I decided to go to my field office to ask them if it would be a big problem. I had a 9am apointment and got right in. The office was pretty easy to find and well marked. The staff was friendly and efficient. And the officer I spoke with was very nice and reassuring!
