An electronic application is denoted by IOE. Please review your I-797 receipt; your processing center is listed below.

ask Emma current location. it can be transferred even from the note on the receipt

Receipt numbers starting with "IOE" indicate that your application was filed online through the USCIS Electronic Immigration System (USCIS ELIS). The "IOE" prefix is used for cases processed electronically, and it doesn't correspond to a specific physical service center. Instead, it signifies that your case is being managed within the USCIS's centralized electronic system.
