However, to apply for e-notification you must file USCIS Form G-1145 (E-Notification of Application/Petition Acceptance) along with your application. Form G-1145 must be attached to the front of the form you are filing.
The purpose of Form G-1145 is to allow the applicant or petitioner who can file their application or petition at one of the three USCIS Lockbox facilities, to receive electronic notification that their application or petition has been accepted.
The Form G-1145 is a single page form that requests electronic notification from the USCIS. When you file this form, you’ll be electronically notified when USCIS accepts your immigration application. This form, as well as its instructions are available free from uscis.gov.
