The U.S. Citizenship and Immigration Services (USCIS) Service Centers were established to handle the mail, file, data entry, and adjudication of most applications for immigration services and benefits. These applications should be mailed to USCIS service centers. Service centers are not staffed to handle walk-in applications or answer questions. Service centers have established special Post Office boxes to receive applications mailed to the center by applicants or petitioners residing in its service area. The applications and petitions processed by each service center are listed on its home page, as are the special Post Office box numbers and zip codes by form type for the service centers using them. Prospective applicants should look at this list of forms to confirm that they are accepted by the service center in their area.
It should be noted that if your request was submitted through the USCIS Electronic Immigration System (ELIS) or is being processed online, the receipt number will begin with IOE, regardless of jurisdiction.
