Noncitizens living in the United States are required to report a change of address to U.S. Citizenship and Immigration Services (USCIS) within 10 days of moving, the agency reminds on its website. The rule covers green card holders as well as people on work, student and other visas.
Holders of A and G diplomatic visas and visitors under the Visa Waiver Program are exempt. People with a pending application should report the change as soon as possible so that notices and appointment letters do not go to an old address.

A post office change is not enough
USCIS says updating an address with the U.S. Postal Service does not update immigration records, and the postal service does not forward USCIS mail. Both need to be changed separately.
The fastest way is the change of address tool in a USCIS online account, which updates records almost immediately; applicants must enter the receipt number of each pending case. The paper Form AR-11 can also be mailed, but USCIS notes that it does not automatically update the agency’s systems.
Penalties under federal law
Under federal immigration law, failing to report a change of address is a misdemeanor punishable by a fine of up to $200 or up to 30 days in jail, and it can also be grounds for removal unless the person shows the failure was reasonably excusable or not willful.
Sponsors who signed an affidavit of support for a relative must also file Form I-865 within 30 days of moving.
