How to Check Your USCIS Case Status
By Pacheco Couceiro
After you file an application or petition with U.S. Citizenship and Immigration Services (USCIS), the agency gives you tools to follow your case online. Many families in Brownsville and the Rio Grande Valley use them to see what has happened on a case and what comes next. This guide explains how to find your receipt number, how to use the Case Status Online tool, how to read USCIS processing times, and which notices USCIS sends. Each point comes from official USCIS pages, linked below.
Step 1: Find your receipt number
To check your case status online, you need your case receipt number. USCIS describes it as a unique 13-character identifier that it provides for each application or petition it receives, used to identify and track its cases. The receipt number consists of three letters followed by 10 numbers. USCIS gives examples of the letters, such as EAC, WAC, LIN, SRC, NBC, MSC or IOE (USCIS: Checking Your Case Status Online).
You can find the receipt number on the notices of action USCIS has sent you.
Step 2: Understand the notice you received
USCIS uses several types of Form I-797 to communicate with applicants and petitioners. USCIS states that Form I-797 is not a form you can fill out; it is a notice the agency sends (USCIS: Form I-797 Types and Functions). According to that page:
- I-797, Notice of Action: communicates receipt or approval of an application or petition.
- I-797A, Notice of Action: issued to an applicant as a replacement Form I-94.
- I-797B, Notice of Action: issued for approval of an alien worker petition.
- I-797C, Notice of Action: communicates receipt or rejection of applications or petitions, transfer of files, fingerprint (biometric), interview and rescheduled appointments, additional actions, and reopening of cases.
- I-797D: accompanies benefit cards.
- I-797E, Notice of Action: issued to request evidence.
- I-797F, Transportation Letter: issued overseas to allow applicants to travel.
Knowing which type you have helps you understand what the notice is telling you. A receipt notice confirms that USCIS received a filing; it is not an approval.
Step 3: Use Case Status Online
USCIS says you can verify your case status online from home, the office or a cell phone by going to Case Status Online through uscis.gov. When you enter your receipt number:
- Omit the dashes ("-").
- Include all other characters, including asterisks ("*"), if they appear on your notice as part of the receipt number.
USCIS encourages you to read its Privacy Act statement, which appears under the "Check Status" button, before checking. The system shows the last action taken on your case and lets you know the next steps, if applicable. To check another case, you can enter a new receipt number in the "Enter Another Receipt Number" field (USCIS: Checking Your Case Status Online).
Step 4: Check processing times
USCIS publishes case processing times on its Check Case Processing Times page. To use it, you select your form, the form category, and the office processing your case. USCIS says to refer to your receipt notice to find this information.
The page currently notes that processing times for certain form types may no longer list a specific service center location and may instead list "Service Center Operations (SCOPS)." USCIS adds that you may continue to receive correspondence listing a specific service center (USCIS: Processing Times, checked October 10, 2026). Because published times change, check the page directly rather than relying on an older printout or screenshot.
Step 5: Consider a USCIS online account
USCIS also points to a personal online account at my.uscis.gov. According to USCIS, the account lets you receive recent case updates, including up to the last five actions on your case, and gives access to applications you filed electronically. USCIS describes the account as free (USCIS: Checking Your Case Status Online).
What to gather and keep together
- Every USCIS notice you have received, in date order
- Your receipt number for each application or petition (each filing has its own)
- A copy of each form you filed and the evidence you sent
- Your current mailing address, and records of any address change you reported to USCIS
- Any appointment notices for biometrics or interviews
Things to know
- Each filing has its own receipt number. If a family filed several forms, each may have a different number to check.
- Dashes are left out, asterisks are not. USCIS's instructions treat these characters differently.
- Status and processing time are separate tools. Case Status Online shows the last action on your case; the processing times page shows published times by form and office.
- The office shown may differ. USCIS notes that processing times may list Service Center Operations while your letters name a specific service center.
- Keep your address current. The Case Status Online landing page links to the USCIS online change of address tool, along with e-Request for case inquiries and a tool to locate a USCIS office.
