Here's a sample i used when we file our k1 last year:
Note: replace the following according to the color.
Red = Replace with the petitioner's name
Green = Petioner's address
Purple = Replace with your fiancee's name
All in all you can change all the content depending on how the two of you meet up but that's exactly the format of the letter. Don't forget the signature over your printed name
Hope that helps!
