23. Standard IV processing is followed, including NCIC namechecks, police certificates, pertinent birth/marriage/divorce/death certificates, standard IV medical exam minus the vaccination requirement, and relationship bonafides, Ref E, 18-25. Unlike K1s and K2s, the IV system will not yet accept K3 as a visa class, and so the systems processing takes place exclusively in NIV. K3s must be issued in the country where the marriage took place, unless there is no IV or NIV issuing post in the country, see Ref E, 15-17. Applicants fill out two copies of the DS-156 NIV application form; they are not required to submit the new DS-157 form. Note that neither an I-864 or an I-134 is required; K3 applicants must present the I-864 when they adjust status in the United States with USCIS. Posts should not routinely require an I-134, except in those cases where the consular officer deems it necessary to overcome any public charge considerations that might arise from documents presented or the interview.
