K-1 fiancé visa: documents you need
The K-1 is two document files, not one: the petition file USCIS reads, and the embassy file the consular officer reads months later. Mixing them up — or preparing only the first — is how K-1 cases stall. This page organizes both stages. Every claim is cited; the form and embassy instructions control; general process description, not advice about any individual case.
Stage one: the I-129F petition file
The USCIS stage documents the relationship's foundation: the petitioner's proof of U.S. citizenship, evidence the couple met in person within the 2 years before filing (or evidence supporting a waiver), both parties' statements of intent to marry within 90 days, and proof that every prior marriage of either party ended.
Meeting evidence is ordinary and documentary — photos together, travel records, correspondence spanning the relationship. The instructions describe the showing; no fixed quantity is right, and coverage beats volume.
Stage two: the embassy file
After approval, the fiancé(e)'s consular file takes over: passport, birth certificate, police certificates where required, the medical examination, and the Department of State's online visa application. The embassy's own instructions govern the details — including any financial documents it requires — and are the controlling checklist for that stage.

The rule that spans both stages
Any document not in English needs a full certified English translation, at either stage. Untranslated or missing items are classic RFE and returned-package generators — and with the petition fee paid and an embassy appointment at stake, the translation is the cheapest component in the file.

What documents does the I-129F need?
The petitioner's proof of citizenship, evidence of meeting in person within 2 years (or waiver evidence), statements of intent to marry, and prior-marriage termination documents — per the form's instructions.
What counts as proof the couple met?
Documentary evidence: photos together, travel records, correspondence. The instructions describe the showing; no fixed quantity applies.
What does the embassy stage require?
The fiancé(e)'s passport, birth certificate, police certificates where required, the medical exam, and the online visa application — with the embassy's own instructions controlling the details.
Do foreign documents need translation?
Yes — full certified English translations at both stages, under 8 CFR § 103.2(b)(3).
