How do I prepare the I-130 package to start the process for a K3?
A..Your package must contain the I-130 and the appropriate documentation listed in the I-130 instructions. For question 21, write down that your spouse will apply for a K3 visa and apply for Adjustment of Status in the United States. The documention required for the I-130 is nearly the same for the I-129F petition, so you might as well prepare both packages at one time, rather than experience surprise and aggravation several weeks later, when you realize you need MORE copies of the exact same stuff.
