We are often asked how to verify the case status. It is a very simple process. You can verify your case status online from your home or office, even from your cell phone! You only have to access USCIS’ Case Status Online directly through uscis.gov.
The Case Status Online landing page shows other quick reference online tools, such as how to change your address online, how to submit an inquiry about your case (e-Request), case processing times and how to locate a USCIS office.
To check your case status using our online tool, you have to have your case receipt number. This receipt number is a unique 13-character identifier that USCIS provides for each application or petition it receives, and it’s used to identify and track its cases. The receipt number consists of three letters followed by 10 numbers. For example, the letters can be EAC, WAC, LIN, SRC, NBC, MSC or IOE. You can find it on notices of action USCIS has sent you.
