U.S. Visa Stamp Explained: How to Read and Understand Your Visa
A U.S. visa stamp is the official label placed inside a passport by a U.S. embassy or consulate. It allows a foreign national to request entry to the United States for a specific purpose and time period.
Many people confuse the stamp with immigration status or assume it controls how long they can stay in the U.S. This guide explains what a U.S. visa stamp is, what each field means, and what it does — and does not — authorize.
Key Takeaways
- A U.S. visa stamp allows you to request entry, not remain indefinitely.
- A U.S. consulate or embassy issues the stamp outside the U.S.
- Your status, not the visa stamp, controls how long you may stay.
- Each field on the visa serves a specific identification or tracking purpose.
What Is a U.S. Visa Stamp?
A U.S. visa stamp (sometimes called a visa foil) is issued only outside the United States by the U.S. Department of State. It allows a traveler to appear at a U.S. port of entry and request admission.
The stamp:
- Controls entry, not length of stay
- Does not grant immigration status by itself
- Can expire while a person remains lawfully in the U.S.
Not all travelers receive a U.S. visa stamp. For example, citizens of Visa Waiver Program countries enter the United States using ESTA authorization and do not receive a stamp in their passport.
How to Read a U.S. Visa Stamp
Below is a labeled example of a U.S. visa stamp. Each section corresponds to a specific field printed on the visa.
Full Name
Your given name and surname (family name) should both match exactly what is printed on the biometric page of your passport.
Issuing Post
Your visa’s issuing post is generally the location of the U.S. embassy or consulate that granted the visa.
Sex
The sex should match exactly the type recorded on the passport.
Birth Date
The date of birth should match exactly the date recorded on your passport.
Visa Control Number
The control number is an internal tracking number used by the Department of State. It is not the visa number and is rarely requested on forms. For the typical visa holder, this number has no significance.
Visa
For the visa field, “R” indicates a regular passport. Other codes, such as “D” or “O,” are used for diplomatic or official passports.
Type/Class
The code under type/class indicates the visa category and describes the purpose of your travel. Examples of common nonimmigrant classes include: B1/B2, F1 and H1B. Immigrants will have a different set of codes with common categories that include CR1, F2A and IR1.
Visa Number
The visa number, sometimes called a visa foil number, is a red number that is generally printed on the bottom right side of newer visa documents. In most cases, the U.S. visa number contains eight numeric characters. In some cases, the number contains one letter followed by seven numeric characters.
Expiration Date
The date your visa expires is the last day that you may seek entry. It does not necessarily mean that you may stay in the United States until this date. Some U.S. visas may be valid for 10 years. However, this only means that the visa holder may use the document to enter the U.S. during the 10-year period. For your “Admit Until Date,” refer to your Form I-94 Arrival/Departure Record →
Issue Date
This date is when the U.S. embassy or consulate issued your visa stamp.
Annotation
The annotation may include additional information about your visa. For example, a J-1 visa may have information about the exchange program. Or an F-1 student’s visa may have your SEVIS number and name of your school.
Entries
This field indicates the number of entries allowed. If there is a number here, you may apply for entry to the U.S. that many times. “M” means that you can seek entry multiple times. "S" is for a single entry. It does not control how long you may stay per entry.
Passport Number
Check to make sure this number matches the number in your passport. A discrepancy will likely be problematic.
What the Stamp Does Not Do
A visa stamp does not:
- Guarantee entry into the United States
- Determine how long you may stay
- Replace immigration status
- Update automatically when your status changes
These misunderstandings are among the most common sources of immigration confusion.

Visa Stamp vs. Immigration Status
A visa stamp allows you to request entry to the U.S. Your immigration status determines how long you may stay and what you may do while inside the U.S.
Status is granted by:
- U.S. Customs and Border Protection (at entry), or
- USCIS (through approval of a change or extension of status)
Therefore, it is possible — and common — to have both an an expired visa stamp and remain in a valid immigration status.
Can You Get a U.S. Visa Stamped Inside the United States?
No. U.S. visa stamps are issued only by U.S. embassies and consulates outside the United States. USCIS does not issue stamps.
If you change or extend status while in the U.S., you generally do not receive a new visa stamp unless you travel abroad and apply at a consulate.
Why the Visa Stamp Still Matters
Even if your status is valid, the visa stamp becomes important when:
- You travel outside the U.S.
- You need to reenter after an absence
- A government agency asks for visa details
- You review past immigration history
Understanding your visa stamp helps you avoid travel problems and paperwork errors.
