USCIS e-Notification of Acceptance (Form G-1145)

Who qualifies

Anyone submitting a paper immigration form to a USCIS Lockbox facility can use Form G-1145. It is not accepted for forms mailed directly to Service Centers or local field offices.

The step-by-step roadmap

1. 1

   Enter Contact Details

   Provide your full legal name, an active email address, and a valid 10-digit U.S. mobile phone number.

   Watch out: Avoid typos in your email address or phone number, as USCIS will not correct them.

   Common rejection reason: Providing an international phone number that cannot accept U.S. SMS messages.
2. 2

   Attach to Front of Filing

   Clip the completed Form G-1145 directly to the top of the very first page of your filing packet.

   Watch out: Do not staple or bury the form behind other documents or forms.

   Common rejection reason: Placing the form inside the packet where intake staff miss it.
3. 3

   Submit with Underlying Form

   Mail Form G-1145 together with your main immigration petition to the assigned USCIS Lockbox address.

   Watch out: Do not mail Form G-1145 alone. It must accompany an eligible petition.

   Common rejection reason: Standalone filings are discarded immediately without processing.
4. 4

   Receive Electronic Notification

   USCIS sends a text or email with your official receipt number once your packet is accepted.

   Watch out: Check your email spam folder so you do not miss the automated message.

   Common rejection reason: Overlooking the text message or having carrier spam filters block the shortcode.
