I noticed that a lot of people have to go check on uscis site to see if they are approved, I found out that if you just open an account with them on here: https://egov.uscis.gov/cris/jsps/login.jsp

Then you can sign up for updates and add as many cases as you like, meaning that you can still get notified on your phone and email even for cases that aren't yours - this uses the same logic as the postal service where you can track a shipment just by entering the tracking number, without the instant notification form. This is handy for these that like to keep checking, you can just create an account, add your case number and pwoned, you don't need to keep checking
