How long does the K-1 fiancé process typically take start to finish?

From I-129F filing to visa issuance, I've seen this commonly run 8–14 months total — a few months for USCIS approval, then more time through NVC and the embassy before the interview. Once the visa is issued, it has a limited window before it expires, so it's worth timing wedding planning around that rather than assuming you can wait indefinitely.
