When applying for a non-immigrant visa to enter the United States, applicants are often required to provide a Control Number. This alphanumeric string serves as a critical identifier throughout the immigration process, linking the applicant to their specific case file. Understanding what this number is, where to find it, and how to use it correctly can significantly reduce confusion and delays.
What is a US Visa Control Number?
A Control Number, also known as a Visa File Number or Case Number, is a unique code assigned by the US Department of State to track a specific visa application. It is generated the moment an application is created in the Department of Labor’s CEAC system or the Department of State’s visa processing systems. This number is distinct from the visa sticker number, which is issued later on the physical document placed inside the passport.
Format and Structure
The format of the Control Number varies depending on the visa category and the year it was issued. Typically, it consists of a combination of letters and numbers. For example, immigrant visa numbers often start with a letter indicating the location or year of filing, followed by a series of digits. Non-immigrant visa numbers are usually shorter and may appear as a single string of numbers and letters. Recognizing this format helps applicants distinguish the Control Number from other identifiers on their forms.
Where to Locate the Control Number
Applicants can find their Control Number in several places, depending on the stage of their application. It is essential to check these documents carefully to ensure accuracy on all forms.
Confirmation Page: The page generated after submitting the DS-160 form online contains the Control Number.
Visa Appointment Letter: The scheduling letter sent by the US Embassy or Consulate includes this number.
SEVIS Fee Receipt: For F, M, or J visa applicants, the I-901 fee receipt displays the SEVIS ID, which functions as a Control Number.
Immigrant Visa Cases: Form I-797C, the Notice of Action, issued by USCIS, contains the A-number, which is the Control Number for green card processes.
How to Use the Control Number Correctly
Providing the correct Control Number is mandatory on various immigration documents. On the DS-160 form, applicants must enter this number in the designated field. During interviews at the consulate, applicants should have this number readily available, as consular officers use it to pull up the application file quickly. Omitting or entering it incorrectly can lead to delays or requests for additional evidence.
Common Mistakes to Avoid
Applicants frequently confuse the Control Number with the passport number or the visa issuance number. It is crucial to note that the Control Number is assigned at the beginning of the process, while the visa sticker number is assigned at the end. Additionally, copying the number incorrectly, such as confusing the letter "O" with the number "0," is a common error that can cause significant administrative hurdles.
Tracking and Updates
Once the application is in adjudication, the Control Number becomes the primary tool for tracking its status. Applicants can check the current stage of their case, such as whether it is under review, approved, or pending additional administrative processing, by entering this number on the official Department of State website. Using this number ensures that the information retrieved is specific to the individual case and not confused with other pending files.
The Difference Between Control Number and Visa Stamp
It is important to understand that the Control Number and the visa stamp (sticker) in the passport are two separate entities. The Control Number is an internal tracking code managed by the US government, while the visa stamp is a physical permit granting the holder permission to travel to a US port of entry. The visa stamp contains its own number, but that number is generated separately and is used for entry rather than case tracking.
