Form I-797, Notice of Action, is the document U.S. Citizenship and Immigration Services (USCIS) mails to tell you something has happened with your immigration application or petition. You never fill it out; USCIS generates it. The letter at the end of the form name (A through F, or no letter at all) tells you exactly what the notice is doing: confirming receipt, granting a benefit, asking for more evidence, scheduling an appointment, or something else. Keep every I-797 you receive, because the receipt number printed on it is how you and USCIS will identify your case from that point on.
The Six Versions of Form I-797
Each lettered version does a different job, and the difference matters. An approval notice is not the same document as a receipt notice, and neither one is the same as a Request for Evidence.
- I-797 (no letter): a general approval notice confirming USCIS approved your application or petition.
- I-797A: an approval notice with a detachable Form I-94 (Arrival/Departure Record). USCIS issues this when you’re already in the United States and have been granted an extension of stay or change of status. The attached I-94 documents your new authorized period.
- I-797B: an approval notice for a worker petition, without an I-94. The beneficiary usually still needs to apply for a visa at a U.S. consulate before entering.
- I-797C: a notice of action covering routine administrative updates. Receipt confirmations, rejections, case transfers, biometrics and interview appointments, rescheduled appointments, and case reopenings all come on this form.
- I-797D: the notice that accompanies a benefit card, such as a Permanent Resident Card or Employment Authorization Document.
- I-797E: a Request for Evidence (RFE). USCIS needs more documentation before it can decide your case.
- I-797F: a transportation letter issued to applicants outside the United States who need authorization to travel.
The legal weight of each version differs. An I-797A with an attached I-94 serves as temporary proof of your authorized status. An I-797C receipt notice explicitly states on its face that it does not grant any immigration status or benefit; it only confirms you filed something.
Reading Your Notice
Every I-797 carries a 13-character receipt number that you’ll use throughout your case. The first three letters identify the USCIS facility handling the filing. Common codes are EAC, WAC, LIN, SRC, NBC, MSC, and IOE. The next two digits are the fiscal year the filing was received, and the remaining digits are your individual case number.1U.S. Citizenship and Immigration Services. Receipt Number
For immigrant visa petitions such as Form I-130 (family-based), I-140 (employment-based), or I-526 (investor), the notice also shows a Priority Date. That date sets your place in line when annual visa numbers are limited. If your petition isn’t in a backlogged category, you may not see a priority date at all.
The notice also lists the petitioner or applicant’s name, the form type filed, and the specific USCIS office handling the case. That office information helps you estimate processing times and know where to direct future correspondence.
To check status, enter the 13-character number (no dashes) at the USCIS Case Status Online tool.2U.S. Citizenship and Immigration Services. Case Status Online You can also link the receipt number to a free account at myaccount.uscis.gov for case history and electronic notifications.
What an I-797 Proves and What It Doesn’t
This is where people get tripped up. An I-797C receipt notice is not proof of legal status. USCIS prints a header on every I-797C stating that the notice does not grant any immigration status or benefit. It proves you submitted an application, nothing more.3U.S. Citizenship and Immigration Services. Form I-797C, Notice of Action
Some state agencies, employers, and benefit-granting organizations do accept an I-797C as collateral evidence that you have a case pending. Whether a particular agency accepts it is up to that agency’s own rules, not USCIS policy.3U.S. Citizenship and Immigration Services. Form I-797C, Notice of Action
An I-797 approval notice (plain I-797 or I-797A) carries more weight because it confirms USCIS actually granted the benefit. An I-797A with a detachable I-94 is especially significant; that I-94 is your official record of lawful status and authorized stay.
Using an I-797 for Form I-9
Certain notices prove work authorization. If you’re a permanent resident who filed Form I-90 to renew an expiring green card, the I-797 receipt notice extends the validity of your Permanent Resident Card for 36 months from the card’s expiration date. You can present the expired card together with the I-797 receipt notice as a valid List A document on Form I-9.4U.S. Citizenship and Immigration Services. USCIS Extends Validity of Expired Permanent Resident Cards from 24 Months to 36 Months for Renewals
If you hold an Employment Authorization Document that qualifies for an automatic extension, your I-797C referencing that extension can be presented alongside the expired EAD for Form I-9 purposes. Employers must accept this combination and should enter the receipt number from the I-797C in Section 2 of the form.5U.S. Citizenship and Immigration Services.

Travel
A standard I-797 receipt or approval notice generally does not authorize international travel or re-entry into the United States. Permanent residents need a valid green card for re-entry, and nonimmigrants typically need a valid visa stamp in their passport. Leaving the country while an application is pending can, in some situations, result in the application being considered abandoned. If you need to travel while a case is pending, check whether you need advance parole or another travel document before booking flights.
If You Receive an I-797E (Request for Evidence)
Treat an RFE as urgent. USCIS is telling you it cannot approve your case without additional documentation, and the notice carries a specific deadline. For most form types, you get 84 days (about 12 weeks). For Form I-539, an extension or change of nonimmigrant status, the deadline is shorter at 30 days. If you’re mailing your response, the regulations give you three extra calendar days beyond the printed due date to account for delivery time.
Missing an RFE deadline has real consequences. USCIS can deny the application as abandoned, or on the merits based on an incomplete record, or both. No extensions are granted. If the evidence has to come from overseas, start gathering it right away instead of waiting.
Fixing Errors or a Missing Notice
If USCIS misspelled your name, printed the wrong date of birth, or made another typographical error on your I-797, submit a correction request through the agency’s online e-Request tool. Select the “Typographic Error” category, enter your receipt number, and describe the mistake, including what the notice says versus what it should say.6U.S. Citizenship and Immigration Services. e-Request – Typographic Error
If the error isn’t a USCIS mistake (for example, you legally changed your name after filing, or you entered incorrect information on your original application), the process is different. See the USCIS “Updating or Correcting Your Documents” page for instructions on returning and replacing the document.
If your I-797 never arrived and you know your receipt number, submit a case inquiry through USCIS in the “did not receive notice by mail” category. Without a receipt number, contact the USCIS Contact Center directly for help.7U.S. Citizenship and Immigration Services. How to Track Delivery of Your Notice or Secure Identity Document or Card
Requesting a Duplicate Approval Notice
When you need an official duplicate of an approval notice that was lost, stolen, or destroyed, file Form I-824, Application for Action on an Approved Application or Petition. Select the “duplicate approval notice” option in Part 2 of the form.8U.S. Citizenship and Immigration Services. Form I-824 Application for Action on an Approved Application or Petition
The filing fee is $590 under the current fee schedule (Edition 03/01/26).9U.S. Citizenship and Immigration Services. G-1055 Fee Schedule Form I-824 is not eligible for a fee waiver through Form I-912, so plan on paying the full amount.10U.S. Citizenship and Immigration Services. Form I-912, Instructions for Request for Fee Waiver
You mail Form I-824 to the USCIS Lockbox that corresponds to the service center that approved your original petition, which you can identify from the three-letter prefix on your receipt number. USCIS updates filing addresses periodically, so if more than 30 days have passed since the edition date on the form, confirm the current address on uscis.gov before mailing. After USCIS receives your I-824, you’ll get a new I-797C confirming the duplicate request is being processed.
