USCIS California Service Center Relocation and Updated Filing Addresses

On 8/12/24, USCIS's California Service Center (CSC) relocated to 2642 Michelle Drive, Tustin, CA.

The CSC has three new PO boxes to receive U.S. Postal Service mail, while UPS, FedEx, DHL, and all other commercial carrier mail will go to CSC’s new facility address. USCIS reminds stakeholders that individuals should always refer to the USCIS website for the most updated mailing address.

USCIS will continue to accept mail at this address until September 30, 2024. After September 30, there will be a two-week grace period, during which time any mail received at the Laguna Niguel PO box will be forwarded to the Tustin PO box. Beginning October 15, 2024, all mail received at the Laguna Niguel PO box will be returned as “Return to Sender.” Individuals responding to USCIS correspondence issued on or before August 12, 2024, such as a Request for Evidence, Notice of Intent to Deny, or Notice of Intent to Revoke, should mail their responses to:
