How do I update my address with USCIS?

You can update your address online through your myUSCIS account, or by filing Form AR-11, which is free and can be submitted electronically.

A few important details:

• Updating your address through your online account for a specific pending case is generally the most reliable way to make sure that case's file reflects the change
• You're required by law to notify USCIS of an address change within 10 days of moving, regardless of your case status
• If a notice (like an interview appointment or RFE) is mailed to an old address because your update didn't take effect in time, that's generally still considered valid delivery — so updating promptly really does matter

If you have multiple pending cases, double-check that the address update applies to all of them, since some systems require updating each case separately.
