Does a Fiance(e) visa couple need to complete the I-134 or the I-864?
A K-1 fiancee visa couple must complete both the I-134 and the I-864 forms. However, the forms are not filed together. Instead, the I-134 form must be completed before the fiancee visa interview at a U.S. consulate. The I-864 will not need to be completed until the couple is married and the foreign national is adjusting status to become a lawful permanent resident.
