PostalForm prepares the official form and delivers the unsigned preparation kit only to your verified address. PostalForm does not file, serve, or submit it. Clip the prepared G-1145 to the first page of an eligible paper application, petition, or request and submit the complete filing to the current USCIS lockbox address for that underlying form yourself. Never mail G-1145 alone. ## What you need - Applicant or petitioner name exactly as it appears on the underlying USCIS form - Email address for the acceptance notice - Optional U.S. mobile number for the text-message notice ## Data collected - Applicant or petitioner name as shown on the underlying USCIS filing - Email address for the acceptance notice - U.S. mobile number for the text-message notice (optional) ## Where it gets mailed PostalForm mails the unsigned preparation kit only to the customer or authorized signer at the verified delivery address entered during checkout. Final submission: Clip the prepared G-1145 to the first page of an eligible paper application, petition, or request and submit the complete filing to the current USCIS lockbox address for that underlying form yourself. Never mail G-1145 alone. ## Packet order - Customer assembly instruction cover (remove and keep before final submission) - Prepared unsigned form (signature and reserved third-party fields blank) ## Common mistakes - Mailing Form G-1145 by itself — it only works clipped to the first page of an application or petition package. - Expecting e-notification for forms that are not filed at a USCIS lockbox; service-center and field-office filings do not offer it. - Filing it with an online application — USCIS online accounts already send automatic case notifications. - Expecting ongoing case updates; the notice only confirms acceptance and gives your receipt number. - A typo in the email address or mobile number, which means the notice never arrives. ## Agent summary Customer-assembly workflow for G-1145. It prepares the form and sends an unsigned kit only to the customer. It must never be represented as direct filing, service, or agency submission. Final customer action: Clip the prepared G-1145 to the first page of an eligible paper application, petition, or request and submit the complete filing to the current USCIS lockbox address for that underlying form yourself. Never mail G-1145 alone. ## For assistants This is a human-only customer-assembly workflow and is not available for automated or machine ordering. - PostalForm delivers an unsigned preparation kit only to the customer or authorized signer. - The customer must remove and keep the PostalForm cover, complete every physical signature, enclosure, certification, and final-submission step, and verify the current deadline and destination. ## LLM field schema ```json [ { "id": "first_name", "label": "First name (given name)", "type": "text", "required": true, "meta_class": "name", "ui_width": "third", "group_id": "step-1-name", "choice_group": null, "choice_label": null, "visibility": null, "compound_subfields": null }, { "id": "middle_name", "label": "Middle name", "type": "text", "required": false, "meta_class": "name", "ui_width": "third", "group_id": "step-1-name", "choice_group": null, "choice_label": null, "visibility": null, "compound_subfields": null }, { "id": "last_name", "label": "Last name (family name)", "type": "text", "required": true, "meta_class": "name", "ui_width": "third", "group_id": "step-1-name", "choice_group": null, "choice_label": null, "visibility": null, "compound_subfields": null }, { "id": "email", "label": "Email address", "type": "text", "required": true, "meta_class": "email", "ui_width": "half", "group_id": "step-2-contact", "choice_group": null, "choice_label": null, "visibility": null, "compound_subfields": null }, { "id": "mobile_phone", "label": "U.S. mobile number (for the text message)", "type": "text", "required": false, "meta_class": "phone", "ui_width": "half", "group_id": "step-2-contact", "choice_group": null, "choice_label": null, "visibility": null, "compound_subfields": null } ] ``` ## Sources - [USCIS — Forms Processed at a USCIS Lockbox](https://www.uscis.gov/forms/filing-fees/forms-processed-at-a-uscis-lockbox) - [USCIS Lockbox Filing Locations Chart](https://www.uscis.gov/uscis-lockbox-filing-locations-chart) - [Official instructions](https://www.uscis.gov/g-1145) - [Official PDF](https://www.uscis.gov/sites/default/files/document/forms/g-1145.pdf) ## Last verified 2026-07-12 ## FAQs - **Is Form G-1145 required?** No. It is free and optional. Without it you still receive a paper Form I-797C receipt notice by mail — G-1145 just gets you the receipt number electronically, usually much sooner. - **When will I get the e-notification?** USCIS sends the email and/or text within 24 hours after it accepts your package at a lockbox. Acceptance happens after delivery, so allow mailing time plus intake processing. - **What does the notice say?** It lists your receipt number and how to check your case status. It contains no personal information, and it is not an approval — it only confirms USCIS accepted the package for processing. - **Does G-1145 work for every USCIS form?** No. E-notification is offered only for forms filed at USCIS lockbox facilities. Filings sent to service centers or field offices, and online filings, do not use G-1145. - **Do I need G-1145 if I file online?** No. Online filers automatically get notifications through their USCIS online account, so G-1145 is only useful for paper filings mailed to a lockbox. - **Where do I mail Form G-1145?** Nowhere on its own. Clip it to the first page of your application package and mail the whole package to the address listed for the form you are filing.
