Form I-797, known as the Notice of Action, is the primary means by which USCIS communicates with anyone who has filed an immigration petition in the United States. Unlike forms such as the I-129, I-130, I-140, or I-485, the I-797 is not filled out by the petitioner — it is generated and sent by the agency itself. When it arrives in your mailbox, it carries critical information about the stage of your case, deadlines to meet, and actions to take.
This guide describes each variant of the I-797, what it means, what information appears on the notice, and how to respond after receiving it. It applies to immigrant visas (family-based, EB-1 through EB-5) and nonimmigrant visas (H-1B, L-1, O-1, F-1, J-1, B-1/B-2, and others).
What Is Form I-797
The I-797 is an official notice printed on plain paper — not on the security stock typical of identity documents — and may arrive by mail or be available through your MyUSCIS account. Although it is a communication document rather than an immigration identity document, it is frequently requested by banks, state motor vehicle departments, and employers. For this reason, every I-797 should be filed in a safe location and photographed for digital backup.
The header of the notice contains two essential pieces of information: the receipt number, a 13-character alphanumeric code that uniquely identifies your case, and the case type, an abbreviation indicating which form was filed. For visas subject to a visa queue, the notice also displays the priority date, the date that determines the petitioner’s position in the Visa Bulletin for immigrant visa number allocation purposes.
I-797 Variants
I-797: General Notice
The basic Notice of Action is issued to record administrative acts in the case, such as receipt of the petition, initial approval, and generation of a case number. It does not replace the I-94 or confer immigration status on its own, but it serves as documentary proof of the current stage of the case.
I-797A: I-94 Replacement
The I-797A is issued when USCIS approves an extension of stay or a change of status within the United States. The bottom portion of the notice includes a tear-off I-94 with the new authorized stay expiration date. This I-94 supersedes any prior record and becomes the official admission document for purposes of status verification, days-of-stay counting, and eligibility for associated employment benefits.
I-797B: Approval of Foreign Worker Petition
The I-797B confirms approval of an I-129 (nonimmigrant) or I-140 (immigrant) petition where the beneficiary is not in the United States at the time of the decision. It authorizes the foreign worker to apply for a consular visa, but does not itself extend a period of stay — lawful presence only begins after admission by CBP at a port of entry. When the I-797B arrives without an attached I-94, the next step is to schedule a visa interview at a U.S. embassy or consulate.
I-797C: Generic Notice of Action
This is the most common variant. It covers a range of operational communications: the receipt notice (confirming receipt of the petition approximately two to three weeks after filing), the rejection notice (returning the package due to a formal error), the transfer notice (informing the petitioner that the case has been moved between service centers), the biometric appointment (scheduling fingerprint and photo collection at an ASC), the interview notice (in-person interview), the reschedule notice, and the motion to reopen (reopening a previously decided case).
Each I-797C contains specific instructions in the body of the document. Dates and addresses printed on the notice take precedence over any verbal information. Missing a scheduled appointment without formally rescheduling may result in abandonment of the case.
I-797D: Benefit Card Notice
The I-797D accompanies the physical delivery of cards issued by USCIS, such as the Permanent Resident Card (green card) and the Employment Authorization Document (EAD). It describes the contents of the mailing and serves as proof of issuance in case the card is lost in transit. Keep the I-797D even after receiving the card — it expedites replacement requests.
I-797E: Request for Evidence
The I-797E is the RFE, in which USCIS requests additional documentation before deciding the case. The notice lists exactly what evidence is required and sets a response deadline, typically between 30 and 87 days depending on the category. A response that is late, incomplete, or fails to address the points raised will result in denial.
Treat the RFE as a second chance, not a sign of failure: statistically, well-supported responses achieve significant approval rates. Submit your response via a tracked delivery service (FedEx, USPS Certified Mail) to preserve proof of timely filing.
I-797F: Transportation Letter
The I-797F is a transportation letter issued to lawful permanent residents who lost their green card abroad, refugees, asylees, and other special cases who need to board a flight to the United States without a standard travel document. The traditional version is delivered at a U.S. embassy or consulate following a specific request.
Priority Date and Receipt Number
The priority date is the date on which USCIS received the petition filed under a category subject to a visa queue — primarily the employment-based categories (EB-1, EB-2, EB-3, EB-4, EB-5) and the family preference categories (F-1, F-2A, F-2B, F-3, F-4). This date establishes the petitioner’s position in the monthly Visa Bulletin published by the Department of State. When the final action date for a given month passes the petitioner’s priority date, a visa number becomes available and the beneficiary may file Form I-485 (adjustment of status) or proceed to consular processing through the NVC.
The receipt number consists of three letters followed by ten digits. The first three letters identify the responsible service center: EAC (Vermont), WAC (California), LIN (Nebraska), SRC (Texas), MSC (National Benefits Center), and IOE (USCIS Lockbox/ELIS for electronic cases). Use the receipt number at egov.uscis.gov to check case status and include it in all communications with the agency.
What to Do After Receiving Your I-797
For a nonimmigrant visa approved while outside the United States, schedule a consular interview at the appropriate embassy or consulate and bring a copy of the I-797B along with the other documents required on the DS-160. For an approval within the United States involving an extension or change of status (I-797A), continue working or studying under the new period until the expiration date shown on the attached I-94.
For an immigrant visa, a beneficiary outside the United States proceeds to the National Visa Center, which coordinates civil documentation, fee payment, and consular interview scheduling. A beneficiary inside the United States with a visa number available per the Visa Bulletin may file Form I-485 to adjust status.
Lost I-797 and Reissuance
If the notice is lost and the receipt number is not recorded elsewhere, log in to your MyUSCIS account — cases filed electronically remain permanently accessible there. For paper-filed cases, schedule an in-person appointment at a USCIS Field Office through my.uscis.gov/en/appointment, bringing a government-issued ID. Formal reissuance of the I-797 is requested via Form I-824, Application for Action on an Approved Application or Petition.
Any change of address while a case is pending must be reported using Form AR-11, Alien’s Change of Address Card, or directly through your online account. Failing to report an address change can result in missing critical notices, including an RFE with a running deadline.
