How Do I Find My USCIS Receipt Number?
Your USCIS receipt number (also called a case number) is the 13-character identifier USCIS assigns the moment your petition or application is received. It is your key to tracking your case, creating an online account, and communicating with USCIS about your application's progress.
The receipt number follows the format XXX123456789 — three letters followed by 10 numbers, no spaces, no dashes. Example receipt numbers include EAC241234567, WAC241234567, LIN241234567, CSC241234567, and IOE241234567.
Where to Find Your Receipt Number
Your receipt number appears on every USCIS notice you have received — your I-797C Receipt Notice (issued when USCIS receives your petition), approval notices, denial notices, and Request for Evidence (RFE) notices. It is also on any paper check or money order you sent with your filing. If you have an immigration attorney, they also have a copy of all your receipt numbers.
Receipt Number Format: What the Letters Mean
The three-letter prefix identifies the USCIS processing location handling your case:
| Code | Service Center | Typical Form Types |
|---|---|---|
| EAC | Vermont Service Center | H-1B, L-1, O-1, I-140, many I-485 |
| WAC | California Service Center | H-1B, L-1, O-1, I-140, many I-485 |
| LIN | Nebraska Service Center | I-485, N-400, I-130 family petitions |
| CSC | Potomac Service Center | I-129 H-1B, L-1, O-1, E-3, TN |
| IOE | Online electronic filing | Forms filed via myUSCIS online account |
Important: Do not confuse your receipt number with your I-94 number (travel document), your A-number (Alien Number, used in deportation cases), or your visa stamp number (on your passport). Only the 13-character USCIS receipt number works with the case status checker.

How to Check Your USCIS Case Status Online
USCIS offers two tools for checking your case status: a public Case Status Online Checker (no account needed) and a myUSCIS online account (full case history after registration).
Option 1: Public Case Status Checker (No Account Required)
The fastest way to check your status is to use the free public checker at uscis.gov/case-status-online. No login or account creation is needed.
- Go to uscis.gov/case-status-online
You do not need to log in or create an account. Enter your full 13-character receipt number exactly as it appears on your notice — no spaces, no dashes. - Click Check Status
Your current case status will display with a brief description. The checker updates daily, but there may be a 24–72 hour delay from when an action actually occurs in your case. - Note any action required
If your status mentions a deadline — such as responding to an RFE or appearing for an interview — take action immediately. Deadlines in immigration are firm.
Option 2: myUSCIS Online Account (Recommended)
For the most complete picture of your case, create a free myUSCIS online account at my.uscis.gov. This gives you:
- Full case history with dates of all actions taken on your case
- Secure messaging with USCIS (Emma chatbot + live agent support)
- Document delivery tracking (when cards and notices were mailed)
- Alert preferences (email or SMS notifications on status changes)
- Ability to respond to RFEs and other requests entirely online
- Access to your approval notice and travel document status
Pro tip: Even if you have an immigration attorney, creating your own myUSCIS account is worthwhile — it gives you direct access to your case history and the ability to check status any time without going through a third party.
Understanding Your Case Status Messages
USCIS case status messages can be cryptic. Here is what the most common ones mean and what action — if any — you should take.
Case Received
USCIS has received your petition and it is in the queue for initial processing. No action needed — this is a normal early-stage status.
Pending
Your case is actively being reviewed by an officer. Processing time depends on form type, service center, and current workload.
Request for Evidence (RFE)
USCIS needs additional documentation to make a decision. The response deadline is in your RFE notice — typically 30 to 84 days. See our RFE response guide →
Interview Scheduled
USCIS has scheduled an interview for your case. Preparation is key — gather all supporting documents listed in your interview notice.
Decision Made / Approved
USCIS has reached a final outcome. An approved case means your petition or application has been granted. Check your mail for the approval notice and next steps.
Case Approved and Dispatched
Your case is approved and your documents (card or notice) have been mailed. Check your address in your USCIS account to confirm they will reach you.
Transfer to Another Office
Your case has been moved to a different service center or field office. The new office's processing times now apply to your case.
Case Denied
Your petition was denied. The denial notice explains the reason. You typically have 30 days to appeal or file a motion to reopen or reconsider.
What to Do If You Receive an RFE
A Request for Evidence (RFE) is one of the most common mid-case statuses and is not a denial — it is an information request. USCIS issues an RFE when the initial evidence submitted was insufficient to make a decision. An RFE gives you a structured opportunity to provide what is missing.
Common reasons for RFEs include:
- Degree equivalence not clearly established (foreign degree vs. U.S. equivalent)
- Employer-employee relationship documentation gaps
- Specialty occupation evidence insufficient (for H-1B cases)
- Missing experience letters, pay stubs, or organizational charts
- Incomplete response to a prior RFE
Respond to your RFE before the deadline. Missing the RFE response deadline is one of the most common reasons petitions are denied — not because the case was weak, but because the applicant never submitted the evidence. Calendar your deadline immediately upon receiving an RFE.
For detailed strategies on responding to RFEs, see our RFE Intelligence Guide, which covers evidence organization, response timelines, and common RFE types by visa category.
Why Is My Case Taking So Long? Processing Time Estimates
Processing times depend on the form type, the service center handling your case, and the current workload across USCIS. Each service center maintains different processing loads, and times can fluctuate significantly over the course of a year.
USCIS publishes typical processing time ranges at uscis.gov/tools/check-processing-times. You can enter your form number and service center to see the current range for your specific case type.

What to Do If Your Case Is Beyond Normal Processing Time
A case is genuinely stuck when it is materially beyond the posted processing time range for its form type and service center. Here is the recommended escalation path:
- Verify the delay is real: Check the current posted processing time for your form number and service center at uscis.gov/tools/check-processing-times. If your case is within the normal range, it is not stuck — patience may be correct.
- Submit an e-request: Log into your myUSCIS account and submit an e-request through the Emma agent for cases outside normal processing time. USCIS typically responds within 30–60 days.
- Contact your congressperson: Write to your representative's district office (not the Washington DC office) with your receipt number and a brief summary. Most offices have dedicated immigration caseworkers and this is often the most effective escalation step.
- Upgrade to Premium Processing: For eligible forms — I-129 (H-1B, O-1, L-1), I-140, and I-765 — file Form I-907 and pay the $2,500 fee for a 15-business-day decision guarantee. If USCIS fails to meet the deadline, they refund the fee.
How to Contact USCIS About Your Case
USCIS offers several channels for getting case information or escalating delays. Here is the recommended path from fastest to most involved.
Emma Chatbot (Fastest)
The Emma chatbot at my.uscis.gov handles common case status questions, processing time inquiries, and e-request submissions 24/7. For existing cases, Emma can often provide current status and next-step information without a live agent. Start here for routine inquiries.
Phone (For Complex Issues)
USCIS Customer Service: 1-800-375-5283 (Monday–Friday, 8 AM – 6 PM ET). For people who are deaf or hard of hearing: 1-800-767-1833. Be prepared for long wait times. Have your receipt number ready before you call.
Local Field Office (Case-Specific Inquiries)
If your case has been transferred to a local field office (for interviews or adjustments), you can make an InfoPass appointment at info.pass.usics.gov to speak directly with an officer at that office. InfoPass appointments are in-person and allow you to discuss case-specific matters that the general helpline cannot address.
Congressional Inquiry (Most Effective for Delays)
Contact your U.S. Representative's or Senator's district office to request a constituent case inquiry. This is one of the most effective tools for escalating genuinely delayed cases. Your congressperson's office will submit an inquiry directly to the relevant USCIS service center and typically receive a response within 30–60 days. This approach is especially effective when e-requests have gone unanswered.
When to Hire an Immigration Attorney
Many immigration cases proceed successfully without an attorney, especially straightforward H-1B, L-1, or O-1 petitions with complete documentation. However, certain situations benefit significantly from professional legal guidance.
Consider hiring an immigration attorney if:
- You have received an RFE and are unsure how to respond or the request seems overly broad
- Your case has been denied and you need to evaluate appeal or motion options
- Your case involves complex facts — prior denials, status violations, unusual employer arrangements
- You are past normal processing time with no response to e-requests or congressional inquiries
- You are self-petitioning (EB-1A, EB-2 NIW) and want an expert to review your evidence package
- You are going through consular processing or an interview and want professional preparation
Get a case review before making major decisions. Our partner immigration attorneys offer a $49 Attorney Prep Session that gives you a 30-minute evaluation of your case, identification of potential issues, and a roadmap for next steps — whether you have an RFE, a denial, or a delay.
