IOE receipts are issued for cases in USCIS's electronic system, ELIS. Every form you file online with a USCIS account gets one, and USCIS also gives IOE receipts to many paper filings it processes electronically.
We've started it with IOE. Type the 10 digits from your notice to see what they mean. It all happens in your browser.
| Form | What it is |
|---|---|
| I-130 | Petition for Alien Relative |

| I-90 | Application to Replace Permanent Resident Card |
| I-539 | Application to Extend/Change Nonimmigrant Status |
| N-400 | Application for Naturalization |
| N-600 | Application for Certificate of Citizenship |
Typical forms, not a complete list. USCIS moves workloads between offices over time.
In IOE0912345678, IOE identifies the USCIS online filing (ELIS) and the 10 digits are the case's number. They don't encode a fiscal year or workday the way service-center receipts do. This is an illustration, not a real case. See the receipt number decoder for the full format.
The prefix alone doesn't tell you how long you'll wait. Timing depends on the form, the category and the office actually working the case, which can change after a transfer. Check USCIS processing times by form, see what your current status means on USCIS case status meanings, or look up your case below for an estimate based on similar cases we track.

A receipt number starting with IOE belongs to the USCIS Electronic Immigration System (ELIS). IOE receipts are issued for cases in USCIS's electronic system, ELIS. Every form you file online with a USCIS account gets one, and USCIS also gives IOE receipts to many paper filings it processes electronically.
IOE isn't a physical office. It means the case is in USCIS's electronic system, ELIS, and any USCIS office with access to that system can work on it.
Commonly I-130, I-765, I-90, I-539, N-400, N-600, among others. USCIS moves workloads between offices over time, so treat this as typical rather than a complete list.
An IOE receipt doesn't name a deciding office. The case can be worked by a service center, the National Benefits Center or a field office, depending on the form.
It depends mostly on the form and category, not the prefix alone. See USCIS processing times by form, or enter your IOE receipt number on our status check for an estimate based on similar cases we track.
Unlike service-center receipts, the 10 digits of an IOE receipt don't encode a fiscal year or workday. They're simply the case's number in the electronic system.
General information, not legal advice. Office workloads change; confirm anything that affects your case with USCIS or an immigration attorney.
