What goes with I-129F: the list from the USCIS instructions

The package per the I-129F instructions, edition 01/20/25 (checked Sep 30, 2026). The chats pass around a template letter of intent to marry - one signed sentence; what it has to show is below.

  • Intent to marry within 90 days. Statements of intent to marry within 90 days of the fiancé(e)'s K-1 admission signed by both, or other evidence of the shared intent. The chat template: the citizen states they are legally able and willing to marry and intend to do so within 90 days of the fiancé(e)'s arrival on a K-1, with a date and signature; the fiancé(e) signs a matching letter.
  • An in-person meeting in the 2 years before filing. A description of the meeting and proof: tickets, stamped passport pages, other evidence. The only exceptions are extreme hardship to the petitioner or a strict, long-established custom of the fiancé(e)'s culture, each proven separately (medical records, statements from religious leaders).
  • Citizenship and prior marriages. A copy of a US birth certificate, naturalization or citizenship certificate, FS-240 or a US passport issued for at least 5 years. If either partner was married before - a divorce decree, annulment or death certificate for every marriage; for a name change - the legal document.
  • Two photos. One colour photo of the petitioner and one of the fiancé(e), 2 x 2 inches on a white background, taken within 30 days of filing, name lightly printed in pencil on the back.
  • Copies, translations, criminal history. Send legible copies, not originals. Every document not in English needs a full translation with a signed translator's certification (complete and accurate, competent, name, date, contact details). The petitioner's convictions and protection orders are disclosed under IMBRA with court-certified records.
