Question: what happens if you don't change your address with uscis?
Answer: Failing to report a new address promptly is a misdemeanor, and could lead to fines, jail time, or even deportation. Fortunately, it's easy to keep USCIS in the loop. Most people can simply update their address online, but some may need to mail in Form AR-11 (officially called the “Alien's Change of Address Card”).
