The National Visa Center is a government facility that's responsible for processing immigrant visa applications after they have been approved by the U.S. Citizenship & Immigration Services. Each case received by the National Visa Center is assigned its case number, informally termed the NVC case number. Just like a USCIS receipt number, an NVC case number is used to track a visa case's progress. You can check the status of your application by calling the NVC and giving your case number along with some personal information about the petitioner and beneficiary of the visa. How do you read an NVC case number? What determines the series of figures assigned to your case?
Obtain your NVC case number from the National Visa Center. Do this by calling the NVC hotline at (603) 334-0700. First provide your USCIS receipt number, which is in your I-797 Notice of Action 1 (NOA1). If your visa package has been received by the facility, either the automated voice recording or a human operator can give you your NVC case number.
Write down your case number. It is a series of three letters and 10 numbers with no dashes or spaces. An example NVC case number looks like this: NWD2008521001.
Split the figures as follows: LLL NNNN NNN NNN, where "L" is a letter and "N" is a number.
Read the three letters from the left. This is the code for the U.S. consulate that has jurisdiction over the visa applicant's location. It is where he will get a visa interview. For example, "NWD" refers to the U.S. consulate in New Delhi, India.
Read the first four numbers following the letters. In this example it is "2008." This is the year that the National Visa Center received the visa application.
Read the next three numbers. This is the day of the year in which the case was received. It is the figure minus 500. For example, "521" means NVC got the package on the 21st day of the year, January 21.
Read the last three numbers in the case number. It tells you the order it was assigned to the consulate that day. In this example, it is "001" so it was the first case created for the New Delhi consulate on Jan. 21, 2008.
