On March 28, 2016, the Lockbox began sending certain cases to the Potomac Service Center. This includes all newly filed Form I-765, Application for Employment Authorization, applications filed by F-1 and M-1 students seeking Optional Practical Training (OPT).

 

 

        When the Lockbox sends your case to the Potomac Service Center, USCIS will send you a notice with your receipt number. Cases sent to the Potomac Service Center will be assigned a receipt number that begins with YSC, which is the prefix used to identify Potomac Service Center filings.

 

        The filing location and instructions for these forms will not change. Please continue to file the forms at the address listed under Where to File in the Form I-765 instructions and on the Web page.

 

 

        Check your case status online with your receipt number. You can also sign up to receive automatic case status updates by email.

 

        If you have any questions regarding your case, submit an inquiry online using our e-Request tool or call the National Customer Service Center (NCSC) at 800-375-5283 (TYY 800-767-1833). When asking about your case status, please provide your receipt number and specify that your case was sent to the Potomac Service Center.

 

        If USCIS sends you any notice (such as a Request for Evidence) please read the notice carefully and follow the instructions provided.

 

        If you move while your case is pending, you must inform USCIS of your address change. You may file a change of address on USCIS website or by calling the NCSC. It is important that you notify USCIS of any address change as soon as possible, so that you continue to receive notifications from USCIS.

 

        The Potomac Service Center is expecting a large number of Form I-765 student filings within the next several months as students prepare for summer employment. Please be patient while the Potomac Service Center prepares for the anticipated surge in applications.
