You can also register for automatic case status updates by email and text message by “creating an account” via the “check your case status” feature on USCIS’ webpage! Think of your account as your home page to view your case status and history for most of the applications and petitions you have filed with USCIS. Creating an account is free and allows you to easily save your receipt numbers and view your entire case history. To sign up, please visit: https://egov.uscis.gov/casestatus/disclaimer.do
After signing up, you will be able to enter the receipts number(s) for your pending application(s) and/or petition(s) and turn on the e-mail or text message notifications.
