After filing your case, you can check its status online. For this, the USCIS tool will ask you to provide the receipt number the agency gave you when you submitted your application.
If you now live at a different location than the one mentioned in your application, you should inform the agency about your new address. More information about filing your address change form is available here.
You should also inform the USCIS if there’s some other unexpected change. For example, if you cannot attend a scheduled interview, you should inform as early as possible. You can request to reschedule by calling the contact center and explaining the emergency. The office location for the interview accepts or rejects rescheduling requests.
If you’ve received a document or card that contains a typographical error, you can submit an e-request for a correction.
