United States law requires that most non-US citizens report a change of address within 10 days of moving by completing a Form AR-11, Change of Address. https://egov.uscis.gov/crisgwi/go?action=coa is the link to the USCIS Online Change of Address website page.
The only persons exempt from this requirement are those who are in the United States on A or G non-immigrant status and certain non-immigrants who do not possess a visa and whose current stay in the United States has not exceeded or will not exceed 29 days.
If you have moved, you need to follow two different steps:
Step 1: File the Form AR-11, which changes your address in the USCIS master database.
Step 2: If you have a pending case you must change your address with the USCIS Service Center where your case is pending as filing the Form AR-11 does NOT change your address with the Service Center. In order to change your address with the Service Center you must contact USCIS customer service at 1-800-375-5283 and follow the prompts.
The AR-11 can either be filed electronically or by mail.
If you choose to submit the completed Form AR-11 by mail please send it to the following address:
