Once USCIS approves your petition, you will be notified that the petition is being sent to the State Department's National Visa Center (NVC) or Kentucky Consular Center (KCC). NVC and KCC will assign the beneficiary a case number starting with FTN, followed by the year (FTN2009123456). KCC will assign case numbers for Diversity Visa applicants that begin with the year with AF in the middle (2009AF12345). For Diversity Visa case numbers, you may omit the 0s after AF (2009AF12345 instead of 2009AF000012345). There are no spaces in case numbers.
If your petition is current, meaning that the State Department can process your visa application, NVC or KCC will send you instructions on how to prepare for your interview. If NVC or KCC has notified you that your case file has been sent to the U.S. Embassy in Freetown and you have not yet received instructions, you may email firstname.lastname@example.org and include your case number in the subject line of your email.
