In immigrant visa cases, the applicant or petitioner will receive Packet 3 forms and instructions from the National Visa Center (NVC). In K-1 fiancée and K-3 visa cases, Packet 3/K Visa Instructions is available here (PDF: 272 KB). The documents and forms DS-160 for all applicant (including K-2 and K-4 who wish to travel with the principle applicant) in Packet 3 must be completed and/or obtained before a visa interview can take place.
Receipt of an I-797 Notice of Approval from the U.S. Citizenship and Immigration Services (USCIS) does not indicate that the case is pending with the U.S. Embassy. It takes 2-6 weeks on average for approved cases to arrive at the Embassy. If you are the applicant or petitioner and has not received an appointment email or letter from the Embassy after 6 weeks from the date you sent us the package 3 (DS-160 confirmation letter), you may send an email to us regarding the status of your case.
Please do not send any of the documents to the Embassy unless you have been specifically instructed to do so by NVC. Any Immigrant visa documents sent to the U.S. Embassy for a case which is not pending at the Embassy will be destroyed.
