USCIS has developed Form G-1145, E-Notification of Application/Petition Acceptance, for petitioners and applicants who file cases at one of the three USCIS lockbox facilities in Chicago, IL, Phoenix, AZ, or Lewisville, Texas. The new form instructs USCIS to send the petitioner or applicant an e-mail and/or text message confirming receipt of the petition or application. The message will provide a receipt number, but will not include the name of the petitioner or applicant for privacy reasons. The electronic notification also will not constitute official notification of acceptance of the case by USCIS. An official receipt notice, Form I-797C, Notice of Action, will continue to be sent via U.S. mail to the petitioner, applicant, or attorney of record, as appropriate.
