This guide is educational. MBO Immigration LLC prepares immigration packets, not legal opinions.

The Form I-797C, Notice of Action is the receipt USCIS mails after they accept and start processing your case. Almost every USCIS workflow generates one. Reading it correctly tells you what was filed, the timeline, and how to use it as legal proof.

What does I-797C look like?

It is a single page printed on light-blue (or sometimes white) USCIS letterhead. The top says U.S. Citizenship and Immigration Services with the agency seal. There are several boxed fields with labels.

Each field, decoded

1. Receipt Number

A 13-character code (3 letters + 10 digits), example: MSC2490012345.

  • The first three letters tell you which service center is processing the case.
  • The next two digits are the fiscal year (e.g., 24 = FY 2024).
  • The remaining digits are sequential.

Common service-center prefixes in 2026:

PrefixCenter
EAC / SRCVermont Service Center / Texas Service Center
WACCalifornia Service Center
NBCNational Benefits Center
IOE / MSCOnline filings (electronic)
YSCPotomac Service Center
LINNebraska Service Center

Service-center routing matters because some forms are processed at different speeds in different centers.

2. Case Type

The form filed: I-130, I-485, I-765, I-131, N-400, I-751, etc.

3. Received Date

The date USCIS marked the packet as received. This is the filing date for visa-bulletin priority date purposes for some categories.

4. Priority Date

For family-based and employment-based petitions (I-130, I-140, etc.), this is the date USCIS will use to determine when an immigrant visa becomes available. Save this date — track it on the USCIS Visa Bulletin.

5. Notice Date

The day USCIS printed the notice. Different from the received date.

6. Page

USCIS uses page numbering when the notice is part of a multi-page bulletin (e.g., approval + biometrics scheduling).

7. Beneficiary / Applicant

The person the case is about — for an I-130 the beneficiary is the relative being petitioned for, the petitioner is the U.S. citizen or LPR sponsor.

8. Address (where it was mailed)

USCIS mailing address on file. Update it via Form AR-11 if you move.

9. Notice content

Free-text body explaining what action USCIS took: receipt, biometrics scheduled, RFE, approval, denial, request for evidence response receipt, etc.

How to use I-797C as proof

The receipt notice has different uses depending on the case:

SituationUse of I-797C
Pending I-485 with I-765 / I-131 not yet approvedCombine with passport / state ID for I-9 reverification while you wait, only when paired with explicit work-authorized status
EAD renewal under auto-extensionI-797C renewal receipt + expired EAD = work authorization for up to 540 days
Pending I-751Receipt automatically extends the conditional green card for up to 48 months — combine with the green card for travel and employment
N-400 pendingCounts as “proof of LPR status maintenance” when paired with the green card

USCIS publishes the official combinations on Form M-274 (Handbook for Employers).

What if you lose your I-797C?

Two options:

  1. Reprint from myUSCIS if your case is online.
  2. Request a duplicate by mail using Form G-1041 (Genealogy Request)? — No. For a duplicate notice you call the USCIS Contact Center at 800-375-5283 and request a duplicate notice be re-issued.

Don’t use the I-797C unless USCIS has actually issued one — fakes do exist online.

Common confusion

  • I-797 vs I-797A vs I-797C — they’re all flavors of the Notice of Action. I-797A is usually an approval notice for nonimmigrant changes; I-797C is the routine receipt / case action.
  • Two receipts mean two cases. If you got one for I-130 and another for I-485, both are tracked separately.
  • The priority date on an I-130 receipt is what controls visa availability — not the I-485 received date.
