I-94 vs Visa Stamp: What's the Difference and Which One Matters
Most immigrants confuse their visa stamp with their I-94. Understanding the difference could save your legal status.
The Confusion That Costs People Their Status
Every year, thousands of immigrants make a dangerous mistake: they think their visa stamp is what keeps them in legal status. It's not.
Your visa stamp and your I-94 are two completely different things. Confusing them is one of the most common immigration mistakes — and the consequences can be severe.
What Is a Visa Stamp?
A visa stamp is the sticker in your passport issued by a US consulate or embassy. It allows you to request entry into the United States.
Key facts about your visa stamp: - It can be expired — and you're still in legal status inside the US - It only matters when you're re-entering the US from abroad - An expired stamp means you need to get a new one at a consulate before your next international trip
What Is an I-94?
Your I-94 is your Admission Record — issued by Customs and Border Protection (CBP) when you enter the US. It shows: - Your class of admission (H-1B, F-1, etc.) - Your authorized period of stay (the critical date)
The I-94 is what actually determines how long you can legally remain in the US.

Which One Should You Track?
Both — but the I-94 date is the one you must never violate.
Here's the practical breakdown:
| Situation | What Matters |
|---|---|
| Working inside the US | I-94 authorized stay date |
| Traveling internationally | Visa stamp must be valid to re-enter |
| Determining legal status | I-94 date |
The Dangerous Scenario
Imagine: Your H-1B visa stamp expires in 2023. Your I-94 says "D/S" (Duration of Status) or lists a date in 2025.
You are completely fine remaining and working in the US — as long as your employer keeps your petition in order.
But if you fly to India for vacation in 2024 with that expired stamp, you cannot re-enter without visiting a US consulate first.
