K‑1 Visa Acronyms & Process Explained

These are the most frequently used terms in the K‑1 visa process. Each acronym represents a specific form, notice, or stage in the journey from petition to entry.

• K‑1
  Nonimmigrant Visa for Fiancé(e)
  The K‑1 visa allows a foreign fiancé(e) of a U.S. citizen to enter the United States for the purpose of marriage. The couple must marry within 90 days of entry.
• I‑129F
  Petition for Alien Fiancé(e)
  The official form U.S. citizens file with USCIS to initiate the K‑1 visa process. This petition establishes the relationship and requests authorization for the foreign fiancé(e) to apply for a K‑1 visa.
• NOA1
  Notice of Action (Receipt Notice)
  The first notice USCIS sends after receiving your I‑129F petition. NOA1 confirms USCIS received your filing, includes your case receipt number, and indicates your petition is in the queue for processing.
• NOA2
  Notice of Action (Approval Notice)
  The approval notice USCIS issues when your I‑129F petition is approved. NOA2 signals that USCIS has reviewed your case and authorized the next step with the National Visa Center and the consulate.
• RFE
  Request for Evidence
  A notice USCIS sends when they need additional documentation or clarification before making a decision on your petition. An RFE includes specific instructions about what to submit and a deadline for response.
• NVC
  National Visa Center
  The processing center that receives approved I‑129F petitions from USCIS and forwards them to the appropriate U.S. embassy or consulate abroad. The NVC assigns a case number and coordinates the transfer of case files.
• CEAC
  Consular Electronic Application Center
  The online system managed by the Department of State where K‑1 visa applicants complete the DS‑160 form and where consulates track visa application status.
• AOS
  Adjustment of Status
  The process of applying for lawful permanent resident status (green card) after entering the U.S. on a K‑1 visa and marrying the U.S. citizen petitioner. This is filed using Form I‑485.
• POE
  Port of Entry
  The airport or border crossing where the K‑1 visa holder first enters the United States. Customs and Border Protection officers at the POE review visa documentation and grant admission.
