— Key Takeaways
- A visa number (visa foil number) is the red number printed on the visa stamp in your passport.
- It is different from your receipt number, A-Number, case number, and travel document number.
- In the immigrant visa context, “visa number availability” refers to whether an immigrant visa is available for your category and country.
- The Visa Bulletin (published monthly by the Department of State) determines when visa numbers are available for preference categories.
- When visa numbers are unavailable, applicants must wait until their priority date becomes current.
The term “visa number” comes up frequently in U.S. immigration, but it can refer to different things depending on the context. For some people, a visa number is the red number printed on their visa stamp. For others, it refers to the availability of immigrant visa numbers under annual caps set by Congress. Understanding these distinctions is essential for anyone navigating the U.S. immigration system.
In this guide, we explain what a U.S. visa number is, where to find it on your documents, how it differs from other identification numbers, and how the visa number allocation system works for immigrants. Whether you are trying to fill out an immigration form or understand why your green card process is taking so long, this article has you covered.
What Is a US Visa Number?
A US visa number typically refers to the unique identification number printed on a U.S. visa stamp (also called a visa foil) placed in a foreign national’s passport by a U.S. embassy or consulate. This number identifies that specific visa issuance and is used for record-keeping and verification purposes.
The visa number is assigned at the time the visa is issued and is unique to that particular visa. If you receive a new visa (for example, upon renewal or a new category), you will receive a new visa number.
In a broader immigration context, the term “visa number” also refers to the immigrant visa numbers allocated by Congress each fiscal year for different categories of immigrants. This is a separate concept that relates to how many people can receive green cards in a given year.
Where to Find the Visa Number on Your Visa Stamp
If you have a U.S. visa stamp in your passport, the visa number is the red number printed on the lower right portion of the visa foil. It is typically an eight-digit number, though the format may vary slightly depending on when the visa was issued.
Here is what you will typically see on a U.S. visa stamp:
- Visa type/class: The visa category (e.g., B1/B2, H-1B, L-1, F-1)
- Issue date: When the visa was issued
- Expiration date: When the visa expires (the last date you can use it to enter the U.S.)
- Entries: Single (S) or Multiple (M)
- Visa number: The red number, usually in the lower right area
- Control number: A separate number used for internal tracking
Note that the visa expiration date is not the same as your authorized period of stay in the U.S. Your authorized stay is determined by your I-94 record.
Visa Number vs. Other Immigration Numbers
The U.S. immigration system uses many different numbers, and it is important to know which is which:
| Number Type | What It Is |
| Visa Number (Visa Foil Number) | The red number on your visa stamp; identifies that specific visa issuance |
| Alien Registration Number (A-Number) | A 9-digit number (A-XXX-XXX-XXX) that identifies you across all immigration interactions |
| Receipt Number | A 13-character code on your I-797 receipt notice that tracks a specific application |
| Case Number (Consular) | The case number assigned by the National Visa Center (NVC) for immigrant visa processing |
| Travel Document Number | Your passport number or the number on a USCIS-issued travel document |
| I-94 Number | Your arrival/departure record number assigned at each U.S. entry |
| SEVIS ID | For F and M visa holders; your Student and Exchange Visitor Information System number |
When filling out immigration forms, read each field carefully to ensure you are entering the correct number. Entering a visa number where a receipt number is requested (or vice versa) can cause processing issues.
How the Visa Process Works: Nonimmigrant vs. Immigrant
Where your visa number comes from — and whether you have to wait for one — depends on which of the two tracks you are on. They work differently from the very first step.
Nonimmigrant visas (temporary stays)
These cover temporary purposes: visiting, studying, or working for a defined period. The path is usually:
- Some categories require an approved petition first — an employer files Form I-129 for H-1B or L-1, for example. Visitor and most student categories do not.
- You complete Form DS-160 online and keep the confirmation number.
- You pay the application fee and schedule an appointment at a U.S. embassy or consulate.
- You attend the interview, or qualify for an interview waiver.
- If approved, the consulate places the visa foil in your passport. The visa number is printed on that foil.
Most nonimmigrant categories are not subject to an annual limit on visa issuance, so there is no queue for a number — it is simply assigned when the visa is issued.
Immigrant visas (permanent residence)
These lead to a green card, and they are numerically limited. The path adds a waiting step:
- A qualifying relative or employer files a petition (Form I-130 or Form I-140), or you self-petition where the category allows it.
- Approval fixes your priority date — your place in line.
- Because Congress caps how many immigrant visas are issued each year, and how many may go to nationals of any one country, you may wait until your priority date is reached. The Department of State tracks this monthly in the Visa Bulletin.
- Once a number is available, you either apply at a consulate abroad through the National Visa Center, or — if you are already lawfully in the United States — file Form I-485 to adjust status.
This is why “visa number” means two different things depending on context. On a nonimmigrant visa it is an identifier printed on the foil. In the immigrant context it also means one of the limited slots allocated each year — which is what people mean when they say a visa number is not yet available.
Immigrant Visa Number Availability
In the context of immigrant visas (green cards), “visa number availability” refers to whether the U.S. government has allocated an immigrant visa number for your specific category and country of birth. This concept is different from the visa foil number described above.
Each fiscal year, Congress authorizes approximately 675,000 immigrant visas to be distributed across various categories (family-based, employment-based, and diversity). Within each category, there are per-country limits to prevent any single country from receiving a disproportionate share.
How Visa Numbers Are Distributed
Immigrant visa numbers are distributed as follows:
- Immediate relatives: Spouses, unmarried children under 21, and parents of U.S. citizens are not subject to annual caps. A visa number is always available for immediate relatives.
- Family preference categories (F1-F4): Subject to annual limits. Wait times depend on the category and country of birth.
- Employment-based categories (EB-1 through EB-5): Subject to annual limits. Some categories and countries face significant backlogs.
- Diversity Visa (DV) Lottery: Approximately 55,000 visas per year for nationals of countries with historically low immigration rates.
How the Visa Bulletin Allocates Numbers
The Visa Bulletin is published monthly by the U.S. Department of State’s Bureau of Consular Affairs. It provides the cutoff dates for each immigrant visa category and country, indicating which applicants can proceed with their immigrant visa or adjustment of status application.
You can access the current Visa Bulletin at travel.state.gov.
Key Visa Bulletin Concepts
- Priority date: The date your immigrant petition (e.g., I-130 or PERM/I-140) was filed. This date determines your place in the visa queue.
- Final Action Date: If your priority date is before this date, a visa number is available, and you can finalize your green card process.
- Dates for Filing: An earlier cutoff date that indicates when you can submit your I-485 or DS-260, even if a final visa number is not yet available. USCIS determines monthly whether applicants can use the Dates for Filing chart.
- “C” (Current): If a category shows “C,” visa numbers are available for all applicants in that category regardless of priority date.
- “U” (Unavailable): If a category shows “U,” no visa numbers are available for that category, and no new applications can proceed.
What Happens When Visa Numbers Are Unavailable
If no visa number is available for your category and country, you are in what is commonly called a “backlog.” This means you must wait until your priority date becomes current on the Visa Bulletin before you can:
- File Form I-485 (Adjustment of Status) if you are in the U.S.
- Complete immigrant visa processing at a U.S. consulate if you are abroad
Backlogs can be significant. For some categories and countries, wait times can span many years or even decades. Factors affecting backlog length include:
- The annual numerical limit for your preference category
- The per-country limit
- The number of applicants in your category and country
- Congressional changes to immigration law (rare but impactful)
- Visa recapture provisions or administrative processing changes
During the waiting period, you must maintain valid immigration status if you are in the United States. If you are abroad, the waiting period is simply a queue—there is no requirement to be in the U.S.
Why Immigration Forms Ask for Your Visa Number
The visa number is a unique identifier tied to a specific visa foil issued to a specific person. Agencies ask for it because it lets them locate the exact issuance record rather than searching by name, which is unreliable across transliterations, name changes and common names.
You will typically be asked for it when:
- Completing a new visa application and disclosing prior visas.
- Filing certain applications with USCIS that ask about your immigration history.
- Completing employment eligibility verification, where an employee chooses to present a document that includes it.
- Corresponding with a consulate about a previously issued visa.
- Requesting records about your own immigration history.
Providing it accurately speeds processing. Providing the wrong number tends to slow it down considerably.
What to Use Before Your Visa Is Issued
A visa number only exists once a visa has actually been issued and the foil printed. If you have applied but have not yet received your passport back, you do not have one.
In the meantime, the identifiers you will actually have are:
- The DS-160 confirmation number for a nonimmigrant application, which appears on your confirmation page.
- The case number assigned by the National Visa Center for immigrant visa cases.
- The receipt number from any related USCIS petition, beginning with a three-letter service center code.
- Your passport number, which identifies you but is not a visa number.
If a form asks for a visa number and you do not have one, the correct response is generally to indicate that none has been issued rather than to substitute a different number. Guessing creates a discrepancy in the record that can take far longer to resolve than leaving the field appropriately blank.
Common Mistakes and What Happens If You Use the Wrong Number
Several numbers appear on or near a visa, and they are easy to confuse.
The Most Frequent Mix-ups
- Using the control number instead of the visa number. Both appear on the visa foil in different positions and formats.
- Using the passport number. The passport is issued by your own government; the visa is issued by the United States. They are unrelated.
- Using the A-Number. The Alien Registration Number identifies a person in immigration records and begins with the letter A. It is not a visa number.
- Confusing digits with letters. Zero and the letter O, and one and the letter I, are the usual culprits when copying by hand.
- Reporting an old visa number after renewal. A new visa carries a new number.
Consequences
Most errors are administrative rather than fatal, but they cost time:
- The agency cannot match the number to a record, which can generate a request for correction or additional evidence.
- Processing pauses while the discrepancy is resolved.
- An inconsistency between what you reported on one form and what appears on another can prompt questions about accuracy, particularly at an interview.
If you discover after filing that you supplied the wrong number, do not simply hope it is overlooked. Correct it through the appropriate channel, and get advice first where the filing is significant. An honest, promptly corrected transcription error is treated very differently from an unexplained inconsistency discovered by an officer.
Keeping a Record of Your Own Numbers
Because these identifiers are requested years apart and passports are replaced, it is worth keeping your own record. A secure note or document listing your visa number, control number, A-Number if you have one, passport number and any USCIS receipt numbers — along with a clear photograph of each document — saves considerable difficulty later, particularly if a passport is lost or a family member needs to supply the information on your behalf.
Store it securely. These numbers are personal identifiers and should be shared only with your attorney, your employer where legally required, and the relevant government agency.

Frequently Asked Questions
1. Where is the visa number on my US visa?
The visa number is the red number located in the lower right area of your visa stamp (visa foil) in your passport. It is typically an eight-digit number.
2. Is the visa number the same as the passport number?
No. The visa number is specific to your U.S. visa issuance and appears on the visa stamp. Your passport number is issued by your home country and appears on your passport bio page.
3. What is the visa foil number?
The visa foil number is another name for the visa number—the red number printed on your visa stamp. It is called a “foil” number because the visa stamp is technically a foil affixed to a passport page.
4. What does ‘visa number unavailable’ mean?
When a visa number is unavailable, it means the annual cap for your immigrant visa category has been reached, and no more visa numbers are available until the next fiscal year or until the backlog moves. You must wait for your priority date to become current on the Visa Bulletin.
5. How do I check if a visa number is available?
Check the monthly Visa Bulletin published by the Department of State at travel.state.gov. Compare your priority date to the cutoff dates for your category and country. If your priority date is earlier than the cutoff, a visa number is available.
6. Can I get a green card without a visa number being available?
No. A visa number must be available for your category before you can receive your green card, either through adjustment of status or consular processing. Immediate relatives of U.S. citizens always have visa numbers available.
7. What is the difference between a visa number and a case number?
A visa number is the identification number on your visa stamp. A case number is assigned by the National Visa Center (NVC) to track your immigrant visa application through consular processing. They serve different purposes.
8. Does my visa number change if I renew my visa?
Yes. Each time a new visa is issued, it receives a new visa number. Your old visa number becomes associated with the expired visa.
9. What is the Visa Bulletin?
The Visa Bulletin is a monthly publication by the Department of State that shows the cutoff dates for immigrant visa categories. It determines who can file for adjustment of status or proceed with consular processing based on their priority date.
10. Why are there per-country limits on immigrant visas?
Per-country limits are set by U.S. immigration law to ensure that no single country receives a disproportionate share of the total immigrant visas available each year. This is why applicants from high-demand countries may face longer wait times.
