Class of Admission on Form I-90 (and Date of Admission Explained)
When completing Form I-90, Application to Replace Permanent Resident Card, many permanent residents get stuck on two fields: class of admission and date of admission. These entries look simple, but they often cause confusion. The terms sound similar, and both appear on your green card.
This page explains what each field means, where to find the information, and how the two fields differ. Understanding the difference helps you avoid delays when replacing a green card.
Key Takeaways
- Class of admission shows how you became a lawful permanent resident and is listed as a code on your green card.
- Date of admission is the date your permanent resident status began, shown as “Resident Since” on the card.
- These two fields serve different purposes and should never be guessed on Form I-90.
- Always copy both values exactly as they appear on your green card to avoid processing delays.
What Does “Class of Admission” Mean on Form I-90?
Your class of admission shows how you became a lawful permanent resident. U.S. Citizenship and Immigration Services (USCIS) assigns this code to identify the immigration category that granted you a green card.
In other words, this code reflects the legal basis for your permanent residence. It does not describe your current status or what you are doing today. Instead, it points to the original immigrant category under U.S. immigration law.
Most class of admission codes include letters and numbers. Because they are not written in plain language, many applicants feel unsure when they see them. That’s normal.
Where to Find Your Class of Admission on a Green Card
Fortunately, you can find your class of admission printed directly on your green card.
On modern cards, the field is clearly labeled “Category” or “Class”. The value will appear as a short code, such as a combination of letters and numbers.

If you have an older green card, the layout may look different. However, the information is still present. If the card is worn or difficult to read, take extra care to copy the code exactly as shown.
Avoid guessing or substituting a visa type. USCIS expects the exact code from your card.
What Is the “Date of Admission” on Form I-90?
The date of admission is the date you became a lawful permanent resident. In other words, the date marks the official start of your permanent resident status.
For many people, this is not the same as:
- The date a visa was issued
- Any date you entered the U.S. as a visitor
- The date you received an approval notice
Instead, it reflects when USCIS or a U.S. port of entry formally admitted you as a permanent resident.
Where to Find the Date of Admission on Your Green Card
The date of admission is also printed on your green card. Typically, the field is labeled “Resident Since”.
The date follows a standard format: month/day/year.

If your card is damaged or the date is unclear, review it carefully under good lighting. If you have renewed your card before, the date should remain the same. In fact, it does not change with each replacement.
Class of Admission vs. Date of Admission on Form I-90: Key Differences
Although both fields appear on your green card, they serve different purposes.
- Class of admission explains how you qualified for permanent residence
- Date of admission shows when your permanent residence began
A common mistake is entering a date where a code is required or confusing the date with an earlier U.S. entry. Therefore, take a moment to verify both fields. It can prevent unnecessary delays.
