Change Your Address with USCIS
All noncitizens in the United States must report a change of address to USCIS within 10 days (except A and G visa holders and visa waiver visitors) of moving. Timely reporting a change of address also helps USCIS to ensure that they mail important notices and documents to the right place.

Use the case status tool to check the status of your case with USCIS. According to USCIS, “The receipt number is a unique 13-character identifier that consists of three letters and 10 numbers. Omit dashes (“-“) when entering a receipt number. However, you can include all other characters, including asterisks (“*”), if they are listed on your notice as part of the receipt number.“
