What this tracker does

  • Decodes each receipt number: which USCIS office received the case and, for paper filings, the commonly used fiscal-year reading of the digits.
  • Compares your case age with the national median processing time USCIS publishes every quarter for that form and category.
  • Shows the typical next steps for the form (biometrics, interview, decision, card production) with links to uscis.gov.
  • Keeps a log of status changes and notes, with export and import. Without an account everything stays in your browser.
  • Optional sign-in syncs your receipt numbers and emails you when a case changes, once USCIS approves our access to its official Case Status API.

USCIS processing times by form

National medians from USCIS’s quarterly report for Apr 1 – Jun 30, 2026 (FY2026 Q3). Your case may differ.

How USCIS receipt numbers work

A receipt number has 13 characters: 3 letters and 10 digits. The letters name the office that received your case:

EAC
Vermont Service Center (VSC)
WAC
California Service Center (CSC)
LIN
Nebraska Service Center (NSC)
SRC
Texas Service Center (TSC)
YSC
Potomac Service Center (PSC)
MSC
Missouri Service Center, now the National Benefits Center (NBC)
NBC
National Benefits Center (NBC)
MCT
Form I-539 filing (change/extension of nonimmigrant status)
IOE
Electronic filing (USCIS ELIS: online filings, immigrant visa fee)

For paper filings the 10 digits are commonly read as a 2-digit fiscal year, a 3-digit workday and a 5-digit sequence number. That reading is community knowledge, not documented by USCIS. IOE numbers come from USCIS’s electronic system and are not split this way.

Frequently asked questions

Where do I find my USCIS receipt number?

It is printed on the receipt notice (Form I-797C) USCIS sends after accepting your filing, and in your USCIS online account for online filings. It has 13 characters: 3 letters followed by 10 digits, for example IOE0912345678 or EAC2190012345.

What do the letters in a receipt number mean?

The 3-letter prefix shows the office that received the case: EAC = Vermont, WAC = California, LIN = Nebraska, SRC = Texas, YSC = Potomac service center, MSC/NBC = National Benefits Center, and IOE = USCIS’s electronic system (online filings).

What does “national median processing time” mean?

It is the number USCIS publishes in its quarterly report: half of the cases it completed in that quarter took this many months or less from receipt to completion. It is a nationwide figure; your office and your case may be faster or slower.

Is the USCIS Case Tracker free, and is it affiliated with USCIS?

It is free and made by Xaplore LLC. It is not affiliated with USCIS or any government agency and is not legal advice; always rely on your official USCIS notices and account.

Does this site check my case status automatically?

Only through USCIS’s official Case Status API, and only after USCIS approves Xaplore’s production access; until then that feature is marked “coming soon”. We never scrape the USCIS Case Status Online website.

About automatic status

Automatic status uses only the official USCIS Case Status API (developer.uscis.gov). Our server asks it about the receipt numbers in signed-in accounts about once a day, and you get one email when anything changes. USCIS’s API keys stay on our server and are never sent to your browser.

USCIS opens production access only to US organizations after a test period, a written attestation with a privacy policy and terms, and a live demo. Xaplore LLC is applying; until USCIS approves it, automatic status is marked “coming soon” and nothing is fetched. Sign in now and your cases will be checked from the first day it is approved.

We never scrape the USCIS Case Status Online website: it is protected against automated access.

Not officially documented

  • Receipt digits: the “fiscal year / workday / sequence” reading of the 10 digits is community knowledge, not documented by USCIS.
  • Status names in the log menu are commonly seen on the USCIS page; USCIS publishes no official list.
  • The percentage estimate is a statistical model built from two published figures, not a USCIS number.
  • The office-level processing-times page (egov.uscis.gov) asks for human verification, so we could not re-check its wording automatically; its “80% of cases” definition and the “receipt date for a case inquiry” rule are as widely reported.
