To file a writ of mandamus, you must draft a formal petition detailing the agency's clear duty to act, your right to relief, and lack of other remedies, then file it in the correct federal court (for USCIS/immigration) or state court (for administrative actions), serve it on all parties (including the U.S. Attorney's office and Attorney General if federal), and follow specific formatting and service rules, ideally with an attorney due to complexity. The process involves exhausting administrative steps first, gathering documents, filing the petition and fee, serving the government, and waiting for a response, which can lead to a court order compelling action, not necessarily a favorable decision.

What is the success rate of the writs of mandamus?

There's no single mandamus success rate, but it's generally high (often cited as 90%+), especially in immigration cases, as filing often prompts agency action, not necessarily approval.

Factors like the specific case's strength, the agency's workload, the assigned attorney's skill, and even the case type (e.g., faster processing EADs) influence outcomes.
