yes they are. a cr1 is an immigrant visa, a k3 is a non-immigrant visa. u must apply 4 the cr1 b4 u can apply 4 the k3. if u use the k3 u will hav 2 eventually get the immigrant visa, either thru finishing the cr1 process or doing adjustment of status.
The reason I ask is because I am preparing the cover letter and I am writing that my husband entered the US on a CR1 visa(b/c technically he did)...i'm not sure if that will make any difference or not.
