Lockbox Intake Processing Tip Sheet
This tip sheet provides additional information on filing your application or petition with a USCIS Lockbox. Tips include:
The Lockbox service provider will assemble each application in the package in the correct processing order before it is scanned; however, we recommend applicants assemble their packages in the following order:
- Check or money order.
- Form G-1145, Request for e-Notification (if applicable),
- Form G-28 (if applicable).
- Form being filed.
- Supporting documentation.
For tips on filing applications with USCIS, please see General Tips on Assembling Applications for Mailing and Form Filing Tips.
For information on requesting a fee waiver, please see our Fee Waiver Guidance, which includes a link to the Form I-912, Request for Fee Waiver. USCIS developed this form to help users understand the fee waiver process and provide the information needed for such requests.
If you sent your application to the wrong filing location, we will forward your application to the correct Lockbox facility. If the application is not processed by a Lockbox facility, it is returned to the applicants.
If applicants or their representatives have specific cases where this is not happening, you should provide additional information to Lockboxsupport@uscis.dhs.gov and we will make any required corrections.
The Lockbox Service provider performs the following activities when processing incoming applications and petitions:
- Receive, open, sort and stage mail;
- Prepare and scan documents;
- Enter document data in system from scanned images;
- Accept or reject applications and related fees based on business rules;
- Balance applications and fees;
- Deposit payments to the U.S. Treasury;
- Send receipt notices for accepted applications to the applicant and designated representative;
- Return rejected applications to the applicant or designated representative;
- Transmit application data to USCIS and payment data to U.S. Department of Treasury; and
- Send application files to the appropriate USCIS service center or field office for further processing.
In addition, USCIS-staffed Case Resolution Units adjudicate fee waiver requests and whenever possible resolve issues with application packages so they can be accepted and sent to a USCIS office for further processing.
If applicants or their representatives have any specific cases where they believe something was lost by a Lockbox facility, please provide details by email to Lockbox Support at email@example.com and we will investigate.
The 90-day period for adjudicating your Form I-765, Application for Employment Authorization, is based on when your form is received at the Lockbox facility. This date is on the notice and it is also sent to the USCIS system for tracking.
Your application will be rejected if it is not filled out completely and does not include correct signatures and the correct fee.
In fiscal year 2017, the Lockbox facilities processed over 11.1 million applications and rejected 9.7% of the applications received. The most common rejection reason is that the correct fees were not enclosed.
The Lockbox facilities accept applications with information that is deemed critical to acceptance of the application. This information is critical because it is used to process our business rules, such as reasons for filing or eligibility categories, and/or it is required by USCIS case management systems.
If your file is rejected, we will send you a rejection notice. If you filed your application or petition with a valid Form G-28, Notice of Entry of Appearance as Attorney or Accredited Representative, we will return it to the attorney or representative on file and send a rejection notice to both you and your attorney or representative.
If your G-28 is not valid (for example, it was not signed), we will not honor it and send all correspondence directly to you.
Please see Filing Your Form G-28 for additional filing tips.
If USCIS has not responded within a reasonable timeframe to an email, attorneys or representatives should reach out to their USCIS Liaison who can email the Chief, Office of Intake and Document Production directly.
