USCIS has created a new Lockbox Filing Location Updates page on their website for customers to keep track of updates they make to lockbox filing locations.

USCIS will update the page regularly, but they always
encourage you to check the “Where to File” section of your form’s
webpage for the most current information on where to mail your
form.

USCIS periodically adjusts filing locations among their lockbox facilities to balance their incoming workload for timely processing.
To receive updates on these lockbox filing location changes, pleasensubscribe to the “Forms Updates” GovDelivery distribution list. In addition to updating the new page, USCIS will issue a GovDelivery email with each filing location update and announce each update through social media.
