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:

SituationWhat Matters
Working inside the USI-94 authorized stay date
Traveling internationallyVisa stamp must be valid to re-enter
Determining legal statusI-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.

What DueVisa Does
