The quickest way to find your date of permanent residence is to look at the front of your Green Card, in the field labeled “Resident Since.” That date is when USCIS considers you to have become a lawful permanent resident, whether you adjusted status inside the United States or entered on an immigrant visa from abroad. If the card is missing or the date looks wrong, several other documents and government records can confirm it.
The “Resident Since” Field on Your Green Card
The Permanent Resident Card, formally Form I-551, prints a “Resident Since” date on its face. That is your official date of permanent residence. The card also shows your Alien Registration Number (A-Number), which you will need for almost every immigration form after this one.1U.S. Citizenship and Immigration Services. List A Documents That Establish Identity and Employment Authorization
USCIS has redesigned the card over the years, so the layout differs depending on when yours was issued. Older cards from the former Immigration and Naturalization Service era look quite different and some lack an expiration date, but the “Resident Since” field has been consistent across every version.
Your Passport Admission Stamp
If you received your immigrant visa at a U.S. embassy or consulate abroad, your date of permanent residence is the day you first entered the United States on that visa. It is not the date the visa was approved or issued.
At the port of entry, a Customs and Border Protection officer stamped your passport with an admission stamp, officially called an ADIT stamp, noting your status as a lawful permanent resident and the date of entry.2U.S. Customs and Border Protection. For U.S. Citizens/Lawful Permanent Residents The passport also contains the Machine-Readable Immigrant Visa (MRIV), which serves as temporary proof of permanent residence for one year from that admission date.3U.S. Citizenship and Immigration Services. Temporary I-551 Stamps and MRIVs
Passport stamps fade. If yours has worn off or your passport has been renewed, the Green Card mailed to you after entry will show the same date in the “Resident Since” field.
Your I-485 Approval Notice
If you adjusted status while already inside the United States, the I-485 approval notice, issued as a Form I-797, Notice of Action, states the effective date your permanent resident status was granted. This is the most reliable backup when your Green Card is unavailable.
Do not confuse it with the I-130 approval notice. The I-130, Petition for Alien Relative, establishes your priority date, which is your place in line for a visa number. It does not grant permanent residence or record a residency date.4U.S. Citizenship and Immigration Services. Visa Availability and Priority Dates Submitting the wrong notice with a naturalization application will slow the case down.
If an Immigration Judge granted your adjustment during removal proceedings, the judge’s written order serves as proof of the approval date, and USCIS issues a Green Card reflecting it.
Checking Your USCIS Online Account
USCIS maintains an online account system at my.uscis.gov where you can view case updates and actions taken on your applications. If you filed your I-485 electronically, your account may show the approval date and case history. It is not a substitute for the Green Card or the approval notice as official documentation, but it is a fast way to confirm a date without digging through paper files.
Requesting Your Immigration File Through FOIA
If none of your personal documents are available, you can get the information directly from USCIS through a Freedom of Information Act request.
As of January 22, 2026, USCIS requires FOIA requests to be submitted online through its FIRST portal at first.uscis.gov. You create a USCIS account and submit your request with your full name, date of birth, and A-Number.5U.S. Citizenship and Immigration Services. Request Records Through the Freedom of Information Act or Privacy Act The portal lets you track the request and receive documents electronically.
Based on the most recently published data, USCIS processed simple FOIA requests in an average of 10 working days and complex requests in about 19 working days, though individual timelines vary. If you cannot submit online, Form G-639 (Freedom of Information/Privacy Act Request) can be mailed, though paper submissions generally take longer.6U.S. Citizenship and Immigration Services.

Backdated Dates for Refugees and Asylees
Refugees and asylees follow different rules, and the “Resident Since” date on their Green Card will be earlier than the date USCIS actually approved the adjustment application. This is not an error.
For refugees, federal law records permanent residence as of the date you first arrived in the United States, even if your I-485 was not approved until a year or more later.7Office of the Law Revision Counsel. 8 USC 1159 – Adjustment of Status of Refugees The implementing regulation confirms that USCIS will admit the applicant for permanent residence “as of the date of the alien’s arrival in the United States.”8eCFR. 8 CFR Part 209 – Adjustment of Status of Refugees and Aliens Granted Asylum
For asylees, the residency date is backdated one year before the date USCIS approves the I-485 application.9eCFR. 8 CFR 209.2 – Adjustment of Status of Alien Granted Asylum If your adjustment was approved on June 1, 2026, your official date of permanent residence would be June 1, 2025.
These backdated dates work in your favor for naturalization. A refugee who arrived on January 1, 2022 and had their I-485 approved in February 2023 still has a residency date of January 1, 2022, which shortens the wait for citizenship eligibility.
Fixing a Wrong Date on Your Green Card
If the “Resident Since” date on your Green Card does not match your approval notice or admission stamp, file Form I-90 (Application to Replace Permanent Resident Card) to correct it. The category you select depends on who caused the mistake.
- If USCIS made the error, select category 2.d or 3.d, indicating incorrect data due to a Department of Homeland Security error. Include the card with the wrong date and supporting documents showing the correct date, such as your I-485 approval notice. There is no filing fee when the mistake was theirs.10U.S. Citizenship and Immigration Services. Immigration Documents and How to Correct, Update, or Replace Them
- If the error is not clearly a USCIS mistake, file under category 2.e or 3.e, pay the standard filing fee, return the incorrect card, and include a written explanation with supporting documentation.10U.S. Citizenship and Immigration Services. Immigration Documents and How to Correct, Update, or Replace Them
Catch errors early. A wrong date can delay a naturalization application or create confusion when you re-enter the country after travel. Compare your Green Card against your approval notice or admission stamp as soon as you receive it.
Why the Date Matters
Your date of permanent residence is the starting line for naturalization eligibility. Most permanent residents can apply for U.S. citizenship after five years of continuous residence, and USCIS lets you file the N-400 up to 90 days before that five-year anniversary.11U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12, Part D, Chapter 6 – Jurisdiction, Place of Residence, and Early Filing If you are married to a U.S. citizen and living together in marital union, the required period drops to three years, with the same 90-day early filing window.12U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12, Part G, Chapter 3 – Spouses of U.S. Citizens Residing in the United States
The same date anchors the continuous residence calculation. An absence from the United States of more than six months but less than a year creates a rebuttable presumption that continuous residence was broken. An absence of a year or more automatically breaks it unless you obtained an approved Form N-470 before departing.13U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12, Part D, Chapter 3 – Continuous Residence Getting your residency date wrong by even a few months can mean a rejected N-400, so confirm it before you file.
