CIS Ombudsman Service <cisombudsman@hq.dhs.gov> 8:03 AM (56 minutes ago) to me Dear Sir, <strong>The Ombudsman's Office has reviewed your request for case assistance and requested U.S. Citizenship and Immigration Services (USCIS) to mail you a new receipt notice. </strong> We will notify you when we receive information from USCIS. If you receive information from USCIS before hearing from us, we request that you kindly let us know by replying to this email. Please note that if the petitioner or applicant changes mailing address, the individual will need to notify USCIS. The individual will need to complete both the Form AR-11 and contact USCIS to update the mailing address for each pending application or petition. USCIS offers an Online Change of Address system that allows the individual to complete both steps electronically: https://egov.uscis.gov/coa/displayCOAForm.do. For more information, please see USCIS' website on Online Change of Address Information, which can be found at https://www.uscis.gov/addresschange. You will need the receipt numbers for all pending applications or petitions. Sincerely, Office of the Citizenship and Immigration Services Ombudsman U.S. Department of Homeland Security Washington, DC I agree to the terms of service Comment
