Change of Address for Non-U.S. Citizen Who Does Not Have any Applications or Petitions Pending with USCIS and Who Has Not Filed an Affidavit of Support
Except for "A" and "G" Nonimmigrants, aliens in the United States for 30 days or longer are required by law to inform USCIS of any address change within 10 days of the permanent change of address. To meet this legal requirement, they must complete and submit a Form AR-11 to USCIS within 10 days from the date the permanent move is completed. The AR-11 is available here (http://shusterman.com/formsusimmigration.html).
Therefore, any person who is not a United States citizen and who is age 14 or older and in the United States for 30 days or longer (except “A" or “G" Nonimmigrants) and who does not have any applications or petitions with USCIS must still complete and submit AR-11 within 10 days from the date the permanent move is completed.
