With Case Tracker for USCIS you can:

• Monitor every application for which you are the case manager and receive timely updates as soon as they are published.
• Track multiple cases at once. This helps you avoid losing track of an application, as well as reducing the risk of duplicate applications.
• Access to every current USCIS bulletin at any time of day or night. If there are changes in an application’s status, you’ll receive alerts and know exactly when you should be looking for updates.
• Receive notifications for every new application. The app uses the case manager’s email address as the case alert.
