Question: where are k1 visas processed?
Answer: The NVC forwards the approved Form I-129F to the U.S. Embassy or consulate where your fiancé(e) will apply for a K-1 nonimmigrant visa. This is generally the U.S. Embassy or consulate where your fiancé(e) lives. The U.S. Embassy or consulate notifies you when the visa interview for your fiancé(e) is scheduled.
