Respond correctly to USCIS mail with our I-797 notice of action checklist. Form I-797 is not an application you file—it is the notice USCIS sends: receipts (often I-797C), biometrics appointments, requests for evidence, approval notices, and related actions. Reading the notice type, dates, and receipt number incorrectly is a common way to miss a deadline or interview. This checklist helps immigration attorneys, paralegals, and applicants identify the notice, calendar deadlines, match it to the right case, and take the next step (appear, respond, or wait). Keep the original. Confirm details against your online account. Not legal advice.

Read the form variant (I-797, I-797A, I-797B, I-797C) and the first paragraph. Do not assume it is an approval.
Receipt numbers start with three letters (e.g., EAC, WAC, IOE). Confirm they match the online account and the file.
Wrong-person notices happen. Contact USCIS or counsel immediately if the identity is wrong.
RFE and biometrics dates are easy to miss. Count from the date on the notice, not the date you opened mail.
Approvals and I-94 tear-offs are often needed for travel, I-9, and later filings. Do not discard the original.
Paper and online can diverge. Download any PDF of the notice from the account as a backup.
See the Request for Evidence (RFE) template. Incomplete or late responses can mean denial.
The underlying form controls. An I-130 approval is not a green card; an I-797A may include a new I-94.
