Form I-797 is not one document. USCIS uses seven versions of the Notice of Action: the plain I-797 plus the I-797A, I-797B, I-797C, I-797D, I-797E and I-797F. The letter in the top corner tells you what the paper does. An I-797A can carry a new I-94 and prove your stay. An I-797C is only a receipt or an appointment letter, and it says so in capital letters across the top.
This guide is for anyone holding one of these notices and trying to work out what it means: an H-1B worker checking an approval, a spouse waiting on a marriage petition, a student reading a biometrics letter, or someone who just saw the case status line “Notice Explaining USCIS’ Actions Was Mailed” and is waiting for the envelope.
USCIS describes each variant on its Form I-797: Types and Functions page. We take those official descriptions one by one, then show you how to read the boxes on the notice itself: receipt number, received date, priority date, notice date and validity dates.
The last three sections cover what goes wrong. A misspelled name or wrong date on an approval notice can cause trouble at a consulate, an airport or an employer’s HR desk, and the fix depends on whose mistake it was. A lost approval notice is replaced with Form I-824, which costs $590 for most filers. A lost receipt notice is not, and that difference catches many people out.
One rule applies to every version: you cannot fill out or file a Form I-797. USCIS issues it to you. If a website offers a “blank I-797” or charges to “file” one, walk away.
Keep every I-797 you receive, including old receipts. They are the paper trail that proves when you filed, what USCIS approved and for how long, and you will be asked for them again at visa interviews, green card interviews and naturalization.
| Form | What USCIS uses it for | Does it grant anything? |
|---|---|---|
| I-797 | Receipt or approval of an application or petition | Approval versions confirm a decision; receipts do not |
| I-797A | Issued to an applicant as a replacement Form I-94 | Yes: the tear-off I-94 records your status and stay |
| I-797B | Approval of an alien worker petition | Confirms the petition approval; no I-94 attached |
| I-797C | Receipt, rejection, transfer, re-open, and biometrics or interview appointments | No. The notice says it grants no status or benefit |
| I-797D | Accompanies benefit cards such as a green card or EAD | The card is the benefit; the I-797D is the cover letter |
| I-797E | Request for Evidence (RFE) | No. It asks you for more proof by a deadline |
| I-797F | Transportation letter issued overseas so the holder can travel | Allows boarding and travel to the U.S. |
I-797C: receipts, appointments, transfers and rejections
The I-797C is the notice most people receive first and most often. USCIS sends it to confirm that a filing arrived (a receipt notice), to return a filing it would not accept (a rejection notice), to report that your file moved to another office (a transfer notice), to tell you a closed case was reopened, and to schedule or reschedule a fingerprint, biometrics or interview appointment.
Since 2012, every I-797C carries a header reading “THIS NOTICE DOES NOT GRANT ANY IMMIGRATION STATUS OR BENEFIT.” USCIS also reminds state agencies and private employers that an I-797C only proves you submitted a request; it says nothing about whether you qualify. Older I-797C notices printed on heavier bond paper with a DHS seal are still valid and worth keeping.
There is one notable exception where a receipt does more than confirm a filing. USCIS has updated the wording on Form I-90 receipt notices so that, presented with an expired green card, the receipt extends the card’s validity for 36 months while the renewal is pending. The receipt number on any I-797C is also what you will use to track the case; our guide to what the LIN, SRC, EAC, WAC and IOE prefixes mean explains which office is handling it.
I-797, I-797A and I-797B: the approval notices
Plain I-797. USCIS uses the base form to communicate receipt or approval of an application or petition. An approved Form I-130 or Form I-140 typically arrives as an I-797 approval notice, with the beneficiary, the classification and the priority date printed on its face.
I-797A. USCIS issues it “as a replacement Form I-94.” In practice this is the approval you get when USCIS approves a change or extension of status for someone already in the United States, such as an H-1B extension filed on Form I-129 or an F-1 to H-1B change. The bottom of the page is a tear-off Form I-94 with a new admission number and an “until” date. That I-94 date, not the visa stamp, controls how long you may stay; we break down the conflicts in I-94 on I-797A vs. admit-until: which date governs your stay.
I-797B. USCIS describes it as the notice “issued for approval of an alien worker petition.” It usually arrives when the approval carries no I-94, most often because the worker is outside the U.S. and will apply for a visa at a consulate. The worker presents it at the visa interview; the stay itself is recorded later by CBP at entry.
I-797D, I-797E and I-797F: cards, evidence requests and travel letters
I-797D is the cover letter that accompanies a benefit card, such as a green card or an Employment Authorization Document. The card is what matters; the I-797D tells you what was mailed and is worth keeping with your records.
I-797E is a Request for Evidence. USCIS sends it when the file is missing something it needs to decide the case. The response date is printed on the notice. Under 8 CFR 103.2(b)(8)(iv), USCIS can give you at most 12 weeks to answer an RFE and at most 30 days to answer a Notice of Intent to Deny, and it may not grant more time. Return the original notice on top of your response packet. Our H-1B RFE response guide walks through building that packet.
I-797F is a transportation letter issued overseas so the holder can travel to the United States. It is a narrow, situation-specific document; if you receive one, follow the travel instructions on it exactly and carry it with your passport.
How to read your notice, box by box
Most I-797 versions share the same top block of labelled boxes, followed by the names of the people involved and a body of text that says what USCIS did. The illustration below is a text mock-up with made-up values, not a real notice. Each callout explains what the box means and when it matters.
Your case’s ID: 13 characters, three letters then 10 numbers. The letters show the processing center. Enter it without dashes at uscis.gov/casestatus, but keep any asterisk printed as part of it.
The form the notice is about. A family that filed three forms will receive three separate notices, each with its own receipt number.
The day USCIS accepted the filing. This is the date that proves an extension was filed on time, before the old I-94 expired.
Your place in the green card line. On an I-140 it is usually the PERM filing date; on an I-130 it is usually the date USCIS received the petition. Compare it against the Visa Bulletin.
The day USCIS generated the letter. Response windows on RFEs are tied to the dates printed on that notice, not the day it reached your mailbox.
What happened and in what category. Check that the class matches what was requested.
The approved validity period. On an I-797A, the I-94 at the bottom carries its own admission number and end date; read both.
Every name and date of birth must match your passport exactly. Errors here are the ones that cause trouble at consulates and ports of entry.
If the notice came after a case status update you did not expect, our explainer on case status messages that look stuck or unavailable covers what each line usually means.
- Name spelled exactly as in your passport
- Date of birth and country of birth correct
- Class or category matches what was filed
- Validity dates match the period requested
- On an I-797A, the I-94 number and end date are filled in
- Receipt number saved somewhere other than the paper itself
What to do if information on your I-797 is wrong
The fix depends on who made the mistake. If the information you submitted was correct and USCIS typed it wrong, that is a USCIS error. USCIS directs people to its online e-Request tool when a document or notice has a mistake believed to be USCIS’s fault. Choose the typographic error option, give the receipt number, say which field is wrong, and attach a copy of the notice plus proof of the correct information, such as your passport bio page.
If the mistake came from your own form, an e-Request will not fix it. The usual path is an amended or corrected filing, which can mean a new fee, so talk to the employer’s attorney or your own before refiling. We cover common cases, including misspelled names and wrong dates, in fixing errors on an I-797A.
Do not use Form I-824 to correct an error. The I-824 instructions say plainly that it is not for “a correction of an error on your previously approved application or petition.”
Lost or never received: e-Request, Form I-824 or FOIA
Never arrived. If your case status shows a notice was mailed but nothing came, start with an e-Request for non-delivery or a call to the Contact Center. Many case status messages state the date after which you can ask for a copy; wait until then. Before you do anything else, confirm USCIS has your current address through your USCIS online account.
Lost after an approval. Form I-824, Application for Action on an Approved Application or Petition, gets you a duplicate approval notice. The fee is $590 for most filers under the Form G-1055 fee schedule, with $0 fees for groups such as VAWA, T, U and Special Immigrant Juvenile filers. The duplicate contains only the Form I-797, not a copy of your petition and not a replacement EAD or green card. USCIS will not process an I-824 if the case is still pending or was denied, and it will not issue a duplicate of an approval that has expired or been revoked. The form is rejected if the receipt number in Part 3 is missing.
Lost receipt notice, or you need a copy for your records. An I-824 only works on approvals. For a receipt notice or other documents in your file, file a Freedom of Information Act request. Since Jan. 22, 2026, USCIS accepts FOIA requests online only, at first.uscis.gov, and asks for the most specific document list possible because narrow requests are processed faster. Our step-by-step USCIS FOIA filing guide covers the form fields, and how to obtain or replace your I-797 online covers the online-account shortcut for cases filed electronically.
| Form I-824, duplicate approval notice (general filing) | $590 |
| Form I-824, VAWA, T, U, SIJ and certain Afghan or Iraqi SIV filers | $0 |
| e-Request for a USCIS typo or a notice never delivered | $0 |
| Problem | Route | Notes |
|---|---|---|
| USCIS typed your details wrong | e-Request (typographic error) | Attach proof of the correct details |
| Notice mailed but never delivered | e-Request (non-delivery) or Contact Center | Update your address first |
| Approval notice lost or destroyed | Form I-824 | $590; approval must not be expired or revoked |
| Receipt notice lost, or need copies of your file | FOIA at first.uscis.gov | Online only since Jan. 22, 2026 |
| Error came from your own form | Amended or corrected filing | May need a new fee; get advice first |
“Notice Explaining USCIS’ Actions Was Mailed”: what that status means
This case status line means USCIS took an action on your case and mailed a letter explaining it. On its own it does not tell you whether the news is good or bad. The letter could be an I-797E Request for Evidence, a Notice of Intent to Deny, a transfer or reopening notice on an I-797C, or a decision.
Once the envelope arrives, use the variant letter and the “Notice Type” line to work out which one you have, then act on any date printed on it. If the letter does not arrive, follow the non-delivery steps in Step 6.
Common mistakes with I-797 notices
After you have read your notice
File every I-797 in date order with its receipt number written on a separate list. When a case is approved, scan the notice the same day; a PDF will not replace a lost original, but it gives you the receipt number and dates you need to file an I-824 or a FOIA request. If the notice raises questions about your stay or your next filing, take the original, not a photo, to any meeting with your employer’s attorney or your own.
Frequently Asked Questions
What is the difference between I-797, I-797A and I-797C?
A plain I-797 communicates receipt or approval of a case. An I-797A is an approval that includes a replacement Form I-94 at the bottom, usually after a change or extension of status. An I-797C is a receipt, rejection, transfer or appointment notice and states that it grants no immigration status or benefit.
Does an I-797C receipt notice mean my case is approved?
No. An I-797C only confirms that USCIS received your filing or scheduled an appointment, and it carries the header ‘This notice does not grant any immigration status or benefit.’ One exception: Form I-90 receipt notices extend an expired green card’s validity for 36 months while the renewal is pending.
What is Form I-797E?
Form I-797E is a Request for Evidence. USCIS sends it when it needs more documents to decide your case. The response date is printed on the notice, and under 8 CFR 103.2(b)(8)(iv) USCIS can give at most 12 weeks for an RFE and 30 days for a Notice of Intent to Deny.
How do I fix a mistake on my I-797 notice?
If USCIS typed your information wrong, submit a typographic error request through the USCIS e-Request tool or call the Contact Center at 800-375-5283, and attach proof such as your passport bio page. If the error came from your own form, you generally need an amended or corrected filing, which may require a new fee.
How do I replace a lost I-797 approval notice?
File Form I-824, Application for Action on an Approved Application or Petition. The general fee is $590. You receive only a duplicate Form I-797, not a copy of the petition or a new card, and USCIS will not issue one for a pending, denied, expired or revoked case.
Can I use Form I-824 to replace a lost I-797C receipt notice?
No. Form I-824 only works on approved applications and petitions. To get a copy of a receipt notice, check your USCIS online account or file a Freedom of Information Act request, which USCIS has accepted online only at first.uscis.gov since Jan. 22, 2026.
What does ‘Notice Explaining USCIS Actions Was Mailed’ mean?
It means USCIS took an action on your case and mailed you a letter about it. The letter could be a Request for Evidence on Form I-797E, a Notice of Intent to Deny, a transfer or reopening notice on Form I-797C, or a decision. The status alone does not say which.
How many characters is a USCIS receipt number on an I-797?
A USCIS receipt number has 13 characters: three letters followed by 10 numbers, such as a WAC, EAC, LIN, SRC, NBC, MSC or IOE prefix. When checking case status online, leave out dashes but keep any asterisk printed as part of the number.
