E-Filing in ACMS

SYSTEM DOWNTIME: CM/ECF and ACMS may be be unavailable from midnight until 9:00 AM Pacific Time every Saturday for system maintenance.

As of May 1, 2021, the court has processed all new petitions for review in immigration cases through the court’s new Appellate Case Management System (ACMS). Additional case types have been added since then and, by October 1, 2023, all new cases will be opened in ACMS. New cases submitted in CM/ECF on or before the effective start date for that case type in ACMS will be processed via CM/ECF unless the Court directs otherwise.

The Administrative Order regarding ACMS provides additional information.

For attorneys, electronic case filing in the ACMS system is mandatory. See Administrative Order Regarding Appellate Case Management System, as adopted December 15, 2021, updated June 30, 2023; Ninth Cir. R. 25-5.

Pro se litigants are encouraged, but not required, to register for electronic case filing and use the ACMS system. More information about pro se filing can be found here under the question “How do I file documents in the Ninth Circuit?”

For more information about CM/ECF, see E-Filing in CM/ECF.
