How USCIS Case Tracking Works

When USCIS receives a petition or application, they assign a unique receipt number and mail you a Form I-797 Notice of Action. This receipt number is your case identifier — you use it to track your case on the USCIS website at egov.uscis.gov/casestatus or with tools like this one.

USCIS processes cases in roughly chronological order within each service center and form type, though some applications are prioritized (premium processing, humanitarian cases). Status updates appear on the USCIS portal within 1–7 days of case activity.

Your Receipt Number Explained

The first three letters identify which USCIS Service Center is processing your case. This matters because different centers have different workloads and processing times — even for the same form type.

USCIS Status Codes Explained

USCIS uses standardized status messages to describe where your case is in the adjudication process. Here are the most common statuses and what they mean:

Status Meaning What to do
Case Was Received USCIS accepted your petition and assigned a receipt number. Clock starts now. Wait. Check back in 30–60 days for movement.
Case Is Being Actively Reviewed An officer has your case on their desk and is examining it. Good sign. Decision typically within 2–6 weeks.
Request for Evidence Was Sent USCIS needs more documentation. You have a deadline to respond (usually 87 days). Contact your attorney immediately. The RFE deadline is non-negotiable.
Response to Request for Evidence Was Received USCIS received your RFE response and is reviewing it. Wait for adjudication. Typical review: 60–90 days.
Notice of Intent to Deny Was Sent USCIS is considering denial but giving you a chance to respond (NOID). Work with an experienced attorney immediately. Response deadline is strict.
Biometrics Appointment Was Scheduled You need to go to an Application Support Center (ASC) for fingerprints and photos. Attend your appointment on time. Bring your appointment notice and ID.
Interview Was Scheduled USCIS requires an in-person interview at a field office. Prepare thoroughly. Bring all original documents and copies.
Case Was Approved Your petition has been granted. Watch for the I-797 approval notice and any cards. Confirm your address is current with USCIS. Expect documents in 2–4 weeks.
Case Was Denied Your petition was not approved. The denial notice explains the reasons. Review the denial carefully. You may have appeal or motion rights (MTR/BIA).
Card Was Delivered to Me USPS has delivered your physical card (EAD, Green Card, etc.) to your address. Inspect the card for accuracy. Report errors at uscis.gov immediately.

Common Status Transitions

Most H-1B, I-140, and I-485 cases follow a predictable path. Understanding the sequence helps you recognize when something is unusual.

Typical H-1B Petition Flow

Case Was Received → Case Is Being Actively Reviewed → Case Was Approved → Card/I-797 Delivered. For premium processing, you should see the Approved status within 15 business days of receipt.

Typical I-485 Green Card Flow

Case Was Received → Biometrics Appointment Scheduled → Case Is Being Actively Reviewed → Interview Scheduled → Case Was Approved → Card Was Produced → Card Was Delivered. The I-485 often takes 12–24 months due to visa number availability requirements for employment-based categories.

When RFEs Occur

RFEs are common (approximately 30–40% of H-1B petitions receive an RFE in some years). They indicate USCIS needs additional evidence — not that your case will be denied. A strong RFE response with thorough documentation results in approval in most cases. Check our RFE Intelligence Hub for patterns by visa type.

What to Do If Your Case Is Stuck

If your case has no status update for a period longer than the official processing time, you have several options:

1. Submit an Online Inquiry

If your case is outside the official processing time by more than 30 days, visit uscis.gov/e-request to submit a case inquiry. USCIS responds within 15–30 business days.

2. Call the USCIS Contact Center

Call 1-800-375-5283 (Monday–Friday, 8am–8pm ET). Have your receipt number, A-Number (if applicable), and date of birth ready. Representatives can see more detail than the online system but cannot expedite cases.

3. Request Expedite Processing

USCIS grants expedite requests in specific circumstances: severe financial loss, urgent humanitarian need, USCIS error, or national interest. Document your reason thoroughly and submit via the online portal.

4. Contact Your Congressional Representative

US Senators and Representatives have casework offices that can submit congressional inquiries to USCIS on your behalf. This is particularly effective for cases exceeding processing time by 6+ months.

📊 Check Current Processing Times

Before submitting an inquiry, verify your case is actually outside the official processing window. Processing times vary by service center and are updated monthly by USCIS.

Frequently Asked Questions

Where do I find my USCIS receipt number?
Your receipt number is printed on Form I-797 (Notice of Action) that USCIS mails after receiving your petition. It starts with 3 letters (EAC, WAC, LIN, SRC, or IOE) followed by 10 digits. Example: EAC2390123456. It is also on any RFE or other USCIS correspondence you receive.
What does "Case Was Received" mean?
"Case Was Received" means USCIS accepted your petition and assigned a receipt number. Your case is now in the queue for adjudication. No action is needed. Processing time begins from this date. Expect the next update in 30–90 days depending on your form type.
What is an RFE and what should I do?
An RFE (Request for Evidence) means USCIS needs additional documentation before deciding your case. You have a fixed deadline to respond — typically 87 days from the RFE date printed on the notice. Failing to respond on time results in automatic denial. Contact an immigration attorney immediately. Do not wait. A well-crafted RFE response with comprehensive evidence leads to approval in the majority of cases.
My case is outside the processing time — what can I do?
If your case exceeds the official USCIS processing time by 30+ days, submit a case inquiry at uscis.gov/e-request. You can also call USCIS at 1-800-375-5283. For cases significantly outside processing time, your immigration attorney can request expedite processing or submit a congressional inquiry through your US Senator or Representative's casework office.
How long does USCIS processing take in 2026?
Processing times vary widely by form type and service center. H-1B I-129: 3–6 months standard, 15 business days premium. I-140 EB-2 NIW: 6–12 months standard, 15 business days premium. I-765 EAD: 3–5 months. I-485 Adjustment of Status: 8–24 months. N-400 Naturalization: 8–14 months. Use our Processing Times tracker for current, up-to-date estimates by form and service center.
What happens after "Case Was Approved"?
After approval, USCIS will mail an I-797 approval notice. For physical cards (EAD, Green Card), USCIS sends them separately via USPS. EAD cards typically arrive within 1–2 weeks of the approval notice. Green cards may take 2–4 weeks. If you don't receive your card within 30 days of the approval notice, contact USCIS to request a replacement.
