The Complete K-1 Process — Step by Step

  1. File Form I-129F with USCIS: The U.S. citizen files the Petition for Alien Fiancé(e). Include relationship evidence: photos together, travel records showing your in-person meeting, communication history (messages, call logs), and any declarations about the relationship.
  2. USCIS Processing (5–8 months avg.): USCIS reviews the petition. An RFE (Request for Evidence) can add 3–6 months to this stage. Avoid RFEs by filing a thorough initial packet.
  3. NVC Transfer (~1 month): After USCIS approves, the case is forwarded to the National Visa Center (NVC), which sends it to the appropriate U.S. embassy or consulate.
  4. Consular Processing — DS-160 & Medical Exam: The foreign fiancé(e) completes Form DS-160 online, pays the visa fee, undergoes a medical exam by an approved physician, and collects supporting documents (police clearance, photos, relationship evidence).
  5. Consulate Interview: The foreign fiancé(e) attends an in-person interview at the U.S. embassy/consulate. The officer will assess relationship authenticity.
  6. Entry & 90-Day Marriage Window: After the K-1 visa is issued, the fiancé(e) must enter the U.S. and marry within 90 days. After marriage, file Form I-485 (AOS) to get a Green Card.
