|09/01/2021. USCIS has created a new Lockbox Filing Location Updates page on their website for customers to keep track of updates we make to lockbox filing locations.
You can use this page to easily see which lockbox form filing locations USCIS has updated and when USCIS made the update.
USCIS will update this page regularly, but USCIS always encourages 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 will periodically adjust filing locations among its lockbox facilities to balance its incoming workload for timely processing.
