What the Non Immigrant Visa Number Actually Is
Your non immigrant visa number is the control number printed in red ink along the bottom right edge of your visa stamp. It is not your passport number, not your case number from the consular application, and not the barcode underneath the photograph. The visa number is a unique identifier assigned to that specific visa foil when the consulate issues it—think of it as the visa's serial number. Every visa stamp gets one, and no two are the same.
The number appears as eight digits, sometimes with a letter prefix or suffix depending on the issuing post. You'll find it in the lower right corner of the visa page, below the machine-readable zone and above or beside the issue date. The red color is intentional—it distinguishes the visa number from other data printed in black, making it easy for border officers to locate quickly.
This number is what Customs and Border Protection records when you enter the United States, what USCIS asks for when you file for a change or extension of status, and what you'll need if you ever apply to replace a lost visa or petition for someone else while you hold nonimmigrant status. It is the key that links your physical visa stamp to the electronic record of your admission and authorized stay. Confusing it with your passport number is one of the most common errors on immigration forms—and one that slows processing or triggers rejection notices.
Why Immigration Systems Track the Visa Number Instead of Your Passport
Passports expire and get renewed; visa stamps do not update when you get a new passport book. A single person might hold five passports over two decades, but each nonimmigrant visa they were ever issued carries a distinct visa number tied to a specific admission record. The visa number is the permanent reference for that entry authorization, regardless of which passport it was stamped in or whether that passport is still valid.
When you enter the U.S., CBP creates an I-94 arrival/departure record linked to your visa number, not your passport number. That I-94 is what proves your lawful admission and sets your authorized period of stay. If you later file Form I-539 to extend or change your status, USCIS pulls your entry record using the visa number you provide on the form. Give them a passport number instead, and the system won't find your admission—your petition may be delayed for a Request for Evidence or denied outright for failure to establish lawful entry.
The visa number also matters in visa foil replacement scenarios. If your passport with the visa stamp is lost or stolen and you need to travel internationally, you cannot re-enter the U.S. without either a valid visa or advance parole. To apply for a replacement visa, the consulate will ask for the original visa number to verify the prior issuance and confirm you are not circumventing a refusal or revocation. Without it, proving your visa history becomes significantly harder.
Where You'll Be Asked for the Non Immigrant Visa Number
Form I-539 (Application to Extend/Change Nonimmigrant Status) has a dedicated field asking for your last nonimmigrant visa number. Leave it blank or enter a passport number, and you've given USCIS incomplete information about your entry. Form I-765 (Employment Authorization Document) asks for it when eligibility is tied to a specific nonimmigrant status. Dependents filing I-539 or I-765 based on the principal visa holder's status must provide both their own visa number and the principal's.
When you check your I-94 record online at cbp.gov/i94, the system cross-references your passport number, date of birth, and visa number to pull the correct admission. If the data doesn't match exactly—including the visa number—you may see "no record found," even though you entered lawfully. The I-94 itself displays your visa number in the "Travel Document" field, confirming which visa stamp authorized your entry.
Visa interview scheduling systems (the DS-160 and consular appointment portals) also ask for prior visa numbers if you've held U.S. visas before. The consular officer reviewing your new application sees your full visa history indexed by those numbers, including any prior refusals, administrative processing holds, or visa cancellations. This is how the system flags patterns—multiple short-term visas, overlapping validity periods, or gaps between expiration and reapplication—that inform adjudication.
The Difference Between Visa Number, Case Number, and Passport Number
Three numbers appear on or relate to your visa process, and they serve completely different purposes:
| Identifier | Where It Appears | What It Tracks | When You Need It |
|---|---|---|---|
| Visa Number | Red ink, bottom right of visa stamp | The physical visa foil and its associated entry authorization | CBP entry, I-539/I-765 filings, I-94 lookup, replacement applications |
| Case Number | DS-160 confirmation page, consular appointment confirmation | Your visa application while it's pending at the consulate | Checking application status, attending your interview, retrieving your DS-160 |
| Passport Number | Passport bio page | The travel document itself, valid for multiple trips and visas | Booking flights, hotel check-ins, applying for any visa, but NOT what USCIS asks for on status forms |
The case number exists only during the application phase. Once the visa is issued, the case number is archived and the visa number becomes the active reference. The passport number identifies you as a traveler globally, but U.S. immigration systems index your records by visa number because that's what proves authorized entry under U.S. law.
Here's the honest answer: if you're filling out a USCIS form and it asks for "nonimmigrant visa number," look at the visa stamp, not the passport bio page. The passport number goes in the passport number field—never substitute one for the other. USCIS does not accept "I didn't know" as a reason to overlook a blank or incorrect visa number field.
What If Your Visa Stamp Is in an Expired Passport?
A visa remains valid until its printed expiration date, even if the passport it's stamped in has expired. U.S. immigration law does not require the visa to be in your current passport—it only requires the visa itself to be unexpired and the passport containing it to be presented at entry alongside your new valid passport. CBP will look at both: the new passport proves your identity and nationality are current, and the old passport carries the valid visa stamp with its visa number.
When you file an extension or change of status, USCIS still wants the visa number from that old passport's stamp. The form instructions make no exception for expired passports; the visa number is the visa number. Dig out the old passport, locate the red number, and enter it accurately. If the old passport is genuinely lost and you no longer have access to the visa number, explain that in a cover letter and provide as much detail as you can—issue date, consular post, visa type—but expect USCIS to ask for additional evidence of your entry, such as your I-94 printout or travel records.
You do not need to renew the visa just because the passport expired, as long as you are not planning to travel outside the U.S. If you leave and want to return, you'll need both a valid passport and a valid visa. At that point, apply for a new visa at a consulate abroad—it will receive its own new visa number. The old visa number still matters for any filings related to your prior entry; the new one becomes the reference for your next admission.
What If You Entered on the Visa Waiver Program (ESTA)?
Visa Waiver Program travelers do not receive a visa stamp or a visa number. Instead, they receive ESTA authorization (an approved Electronic System for Travel Authorization application) and an I-94 admission record upon entry. The I-94 is still generated, but the "visa number" field on it will be blank because no visa was issued. When filling out forms that ask for a nonimmigrant visa number, VWP entrants write "EXEMPT" or "VWP" or leave the field blank, depending on the form's instructions. Check the specific form's guidance—some explicitly tell VWP travelers what to enter; others assume the field does not apply.
This distinction matters because VWP entries carry different extension and change-of-status rules. Most VWP admissions cannot be extended or changed to another nonimmigrant status except in very limited circumstances (immediate relative petitions or certain emergency situations). If you entered on ESTA and are now trying to file I-539, consult an immigration attorney before submitting—VWP's statutory restrictions may bar the relief you're seeking, regardless of what you write in the visa number field.
What If You Have Multiple Visas in the Same Passport?
If you hold more than one valid U.S. visa—for example, an unexpired B-1/B-2 from 2023 and a new H-1B issued in 2026—each visa has its own unique visa number. When you enter the U.S., CBP will ask which status you are entering under, and the officer will record the visa number from the stamp you are using for that entry. That visa number is the one tied to your I-94 for this admission.
When you later file for an extension or change, report the visa number corresponding to the status you entered under, not every visa number in your passport. If you entered as an H-1B worker, give the H-1B visa number. If you entered as a tourist under B-2 and then changed status to F-1 while in the U.S., the B-2 visa number is still your last visa number of entry, even though you now hold F-1 status—because you haven't exited and re-entered on an F-1 visa. USCIS wants the visa number from your most recent admission, which is an entry fact, not a status fact.
Comparison: Visa Number vs. Receipt Number vs. A-Number
Immigration processes generate multiple identification numbers, and knowing which one a form is asking for prevents costly errors:
| Number Type | Format | What It Identifies | Used On |
|---|---|---|---|
| Visa Number | 8 digits, sometimes with letter, red ink on visa stamp | The specific visa foil issued by a consulate | I-539, I-765, I-94 lookup, consular replacement |
| Receipt Number | Starts with three letters + 10 digits (e.g., WAC2690012345) | A petition or application filed with USCIS | Case status checks, RFE responses, approval notices |
| A-Number (Alien Registration Number) | 7–9 digits, sometimes prefixed with "A" | An individual's permanent immigration file with USCIS | Green card, removal proceedings, certain benefit applications |
The visa number never changes once issued; it's a historical marker of that visa stamp. Receipt numbers are generated every time you file something new with USCIS. An A-number, if you have one, follows you across filings and status changes for life. Do not mix them up—USCIS forms are explicit about which one they want, and entering the wrong identifier can cause your case to be misrouted or rejected.
How Attorneys Use the Visa Number in Case Preparation
When preparing an extension or change-of-status petition, immigration attorneys at firms like the Law Offices of Peter D. Chu cross-check the visa number you provide against your I-94 record to confirm lawful entry. If the numbers don't match, it signals either a data-entry error or a deeper issue—perhaps you entered on a different visa than you remember, or the I-94 system hasn't updated correctly. Catching that mismatch before filing prevents USCIS from issuing an RFE or denial based on inability to verify admission.
The visa number also appears in dependency chains. If a spouse or child is filing based on the principal nonimmigrant's status (for example, H-4 dependents of an H-1B holder), the dependent's form asks for both their own visa number and the principal's. Misreporting either one can break the link USCIS uses to confirm the derivative relationship and eligibility. Experienced legal teams verify every visa number in the household before submitting a multi-beneficiary petition.
In replacement or re-issuance cases—where a visa was lost, a passport was stolen, or a name legally changed—the consulate needs the original visa number to pull the issuance record and confirm the visa wasn't revoked before issuing a duplicate. Attorneys request that number from clients early in the process; without it, consular staff may require additional evidence (prior I-94s, entry stamps, approval notices) to reconstruct the visa history, delaying your travel.
What If You Never Received a Visa Number (Consular Processing Issue)?
In extremely rare cases, an applicant reports receiving a visa stamp with no red control number printed. This is almost always a printing defect at the consular post. If you notice it before leaving the consulate, alert the staff immediately—they will reprint the foil. If you discover it after you've left, contact the consulate by email with a photo of the visa page. Do not attempt to enter the U.S. with a defective visa; CBP may refuse entry if the visa lacks a control number, as the system cannot record your admission without one.
More commonly, applicants confuse other numbers on the visa for the visa number. The barcode number, the annotation field (where consular officers sometimes write notes), and the passport number all appear in black ink elsewhere on the page. Only the red number in the lower right corner is the visa number. If you see multiple strings of digits, the one in red is the one you need.
When the Visa Number Doesn't Matter (and When It's Critical)
You do not need to memorize your visa number for everyday purposes. It does not appear on your boarding pass, is not checked at hotels, and plays no role in domestic travel within the U.S. But it becomes critical the moment you interact with USCIS or CBP on status issues—extensions, changes, I-94 corrections, re-entry after international travel, and benefit applications tied to your nonimmigrant classification.
The Law Offices of Peter D. Chu recommends photographing or scanning every visa stamp immediately upon receiving it. Store the image in a secure cloud folder alongside your passport scan and I-94 printout. If your passport is lost or stolen, you'll still have the visa number to report to the consulate and to USCIS for any pending applications. The two minutes it takes to save that image can prevent weeks of delays later.

Frequently Asked Questions
Where exactly is the non immigrant visa number located on my visa stamp? ▼
The non immigrant visa number is printed in red ink in the lower right corner of your visa stamp, below the machine-readable zone and near the issue date. It is typically eight digits, sometimes with a letter prefix or suffix. The red color distinguishes it from other data printed in black, such as your passport number or the barcode.
Is the visa number the same as my passport number? ▼
No. Your passport number identifies the travel document and appears on the passport bio page in black ink. The visa number is a unique control number assigned to the visa stamp itself, printed in red on the visa foil. USCIS and CBP track your entry and status by visa number, not passport number. Using the wrong one on forms causes processing delays or rejections.
What if my visa is in an expired passport—do I still use that visa number? ▼
Yes. A visa remains valid until its printed expiration date, even if the passport it is in has expired. When filing USCIS forms, report the visa number from the stamp in the old passport. You will need to present both the expired passport (with the valid visa) and your current valid passport when entering the U.S., but the visa number itself does not change or expire separately from the visa.
What should I enter in the visa number field if I entered under the Visa Waiver Program? ▼
Visa Waiver Program travelers do not receive a visa stamp or visa number. Most forms instruct VWP entrants to write 'EXEMPT,' 'VWP,' or leave the visa number field blank. Check the specific form's instructions—some provide explicit guidance for VWP entries. Your I-94 record will also show the visa number field as blank because no visa was issued.
I have two valid visas in my passport—which visa number do I report on USCIS forms? ▼
Report the visa number from the visa you used to enter the U.S. on your most recent admission. Each visa has its own unique number, but USCIS wants the number corresponding to the status under which you were admitted. If you entered as a B-2 tourist and later changed status to F-1 inside the U.S., the B-2 visa number is still your last visa number of entry, since you have not exited and re-entered on an F-1 visa.
What happens if I enter the wrong visa number on my I-539 or I-765 application? ▼
USCIS uses the visa number to verify your lawful entry and current status. An incorrect or missing visa number can result in a Request for Evidence asking you to prove your admission, or outright denial for failure to establish eligibility. If you realize the error after filing, contact USCIS immediately—some errors can be corrected by filing an amended form or responding to an RFE, but it is far better to verify the number before submitting.
Can I look up my visa number online if I have lost my passport? ▼
No official database allows you to retrieve a visa number by name or date of birth alone. Your I-94 arrival/departure record at cbp.gov/i94 displays the visa number used for your most recent entry, so if you can access that record (using your passport number and other details you remember), you can recover the number. Otherwise, contact the consular post that issued the visa—they may be able to provide the number from their records if you supply sufficient identifying information.
Do I need a visa number if I adjusted status to a green card while in the U.S.? ▼
If you adjusted status without leaving the U.S., you still entered originally on a nonimmigrant visa (unless you were paroled or admitted under another mechanism). That entry visa number may be requested on certain forms or background checks even after you become a permanent resident, as it is part of your immigration history. Keep a record of it. Your green card itself will have an A-number and a USCIS number, but those are separate identifiers—they do not replace the historical visa number from your entry.
