In fiscal year 2014, the USCIS Lockbox rejected about 8% of the more than 7.7 million applications it received. CLINIC affiliates have vast expertise and achieve amazing results for their clients every day, but they still report occasional issues with application rejections. Such rejections can be frustrating and cause delays and complications in your clients’ cases. Here are a few tips for resolving issues with application rejections. 


Tip #1

When submitting your application, you should check your package for completeness, signatures, and correct mailing address. The most common reasons for rejection from the USCIS Lockbox are incomplete applications, missing signatures, and incorrect fees. Keep copies of the entire application package, including supporting documentation, the mailing address you used, and the fee check you sent.

Tip #2

We recommend that you submit packages via courier wherever possible, and always ensure that you have a reliable tracking mechanism. CLINIC affiliates have occasionally reported significant delays in USPS delivery times, so we recommend using a courier instead USPS, particularly if you are facing a deadline. Keep in mind that courier deliveries use different addresses than USPS deliveries, so be sure to check the form instruction page for the correct address. Track and keep proof of delivery!

Tip #3

 If your application is rejected, review the notice that was sent by USCIS and the reason for rejection. If you believe that you can overcome the rejection by resubmitting with additional information and documentation, we recommend you do so.

Tip #4

If you believe the rejection by the USCIS Lockbox was in error, you may submit an inquiry through the USCIS Lockbox Support email to request review of the rejection. 

  • Provide key identifying information including the form number; receipt number; petitioner and/or applicant name, mailing address, and date of birth; and your G-28 info.
  • Attach a copy of the rejection notice as well as evidence that the rejection/denial was improper.
  • You should expect to receive a response within 5 days. 

Tip #5

If you do not receive a response from the Lockbox, continue to advocate. You may resubmit the application, with further evidence that the initial rejection/denial was in error or you may consider contacting the CIS Ombudsman’s Office. If you are a member of CLINIC, you may also reach out to our Advocacy team to request individual case assistance.

Tip #6

If your application was received (your tracking number confirms delivery), but you have not received a receipt within reasonable time (30 days), send a message to the Lockbox Support email to request the receipt information. You should be sure to provide key identifying information including the form number; petitioner and/or applicant name, mailing address, and date of birth; your G-28 info; and proof of delivery (tracking info). You should expect to receive a response from Lockbox support within 5 days.


Even the best, well-documented cases can be met with a rejection. The above tips can help you to prevent and remedy a rejection and put your client’s case back on track. If you need additional guidance on preparing the particular application at issue, see CLINIC’s resources page at our website.
