K-1 Fiancé Visa Application: Complete Document Checklist

1. Form I-129F, Petition for Alien Fiancé(e) (Revised 2025 Edition)

• What it is:
  Form I-129F is the main petition that a U.S. citizen files with U.S. Citizenship and Immigration Services (USCIS) to start the K-1 fiancé visa process. This form tells USCIS that you want to bring your fiancé(e) to the United States 🇺🇸 so you can get married within 90 days of their arrival.

• Where to get it:
  Download the latest version directly from the USCIS Form I-129F page. Always use the most current edition, as older versions will be rejected.

• Formatting requirements:

  • Use the 2025 edition, which became mandatory on May 1, 2025.
  • Fill out the form in black ink if using paper, or type directly into the PDF.
  • Sign and date the form in the correct spot.
  • Attach all required evidence (see below).
  • Do not leave any required fields blank. If something does not apply, write “N/A” or “None.”
  • Double-check that all information matches your supporting documents.
• Translation needs:
  If you include any documents in a language other than English, you must provide a certified English translation. The translator must certify that the translation is complete and accurate.

• Common issues:

  • Using an outdated form version.
  • Missing signatures or dates.
  • Incomplete answers or missing evidence.
  • Not providing proof of meeting in person within the last two years (unless you qualify for an exception).
  • Submitting unclear or low-quality copies of supporting documents.

2. Valid Passport of the Foreign Fiancé(e)

• What it is:
  The foreign fiancé(e) must have a valid, unexpired passport from their home country. This passport is needed for the visa application and for travel to the United States 🇺🇸.

• Where to get it:
  Apply for or renew the passport at the foreign fiancé(e)’s local government office or passport authority.

• Formatting requirements:

  • The passport must be valid for at least six months beyond the intended date of entry into the United States 🇺🇸.
  • Provide clear, color copies of the biographical page (the page with the photo and personal details).
  • Bring the original passport to the visa interview.
• Translation needs:
  If the passport contains important information in a language other than English (such as endorsements or remarks), provide a certified English translation.

• Common issues:

  • Expired or soon-to-expire passports.
  • Damaged or unreadable passports.
  • Inconsistent personal details compared to other documents.

3. Birth Certificate of the Foreign Fiancé(e)

• What it is:
  The birth certificate proves the foreign fiancé(e)’s identity, date of birth, and family background.

• Where to get it:
  Request a certified copy from the local civil registry or government office in the fiancé(e)’s country of birth.

• Formatting requirements:

  • Submit a certified copy, not a photocopy or scan of an uncertified document.
  • The certificate must show the full name, date and place of birth, and parents’ names.
  • If the original is lost, request a new certified copy from the issuing authority.
• Translation needs:
  If the birth certificate is not in English, provide a certified English translation. The translator must include a signed statement certifying the translation’s accuracy and completeness.

• Common issues:

  • Submitting an uncertified or unofficial copy.
  • Missing information (such as parents’ names).
  • Failing to provide a translation or using an unofficial translation.

4. Police Clearance Certificates

• Where to get it:

  • Request from the police or government agency in each country where the fiancé(e) lived.
  • The U.S. embassy or consulate website in each country usually lists the correct office and process.
• Formatting requirements:

  • Not explaining why a certificate cannot be obtained if it is unavailable.

5. Medical Examination Report

• What it is:
  The foreign fiancé(e) must have a medical exam by a doctor approved by the U.S. Department of State. The exam checks for certain diseases and ensures the fiancé(e) has required vaccinations.

• Where to get it:

  • Schedule the exam with a panel physician listed by the U.S. embassy or consulate in the fiancé(e)’s country. The embassy website provides the list of approved doctors.
• Formatting requirements:
  • The doctor will give the fiancé(e) a sealed envelope with the medical report and vaccination records.
  • Do not open the sealed envelope. Bring it to the visa interview.

• Translation needs:
  The panel physician will provide the report in English or with an official English translation.

• Common issues:

  • Scheduling the exam too late, causing delays.
