A mandamus action is a federal lawsuit filed under the Mandamus Act and Administrative Procedure Act to compel a government agency to take action on an unreasonably delayed immigration application. When USCIS or another agency fails to adjudicate a petition or application within a reasonable time, the affected individual may seek court intervention to force the agency to act. Mandamus does not guarantee approval of the application but requires the agency to make a decision.

Frequently Asked Questions
How long must my case be pending before I can file mandamus?
There is no fixed waiting period. Courts consider whether the delay is unreasonable under the TRAC factors, which include the rule of reason, the statutory timeframe for action, the effect on human welfare, and the agency's competing priorities. Cases pending well beyond normal processing times may be candidates for mandamus.
Will filing a mandamus case hurt my application?
Filing a mandamus case should not negatively affect the merits of your application. The lawsuit only asks the court to order the agency to decide your case—it does not ask the court to order approval. Agencies must still evaluate applications based on eligibility.
What are the TRAC factors courts consider?
The TRAC factors come from a D.C. Circuit case and include: (1) rule of reason governs timing; (2) statutory timetable; (3) effect on human health and welfare; (4) prejudice to other pending matters; (5) nature of interests at stake; and (6) agency's explanation for delay. Courts balance these factors to determine if delay is unreasonable.
What happens if the agency adjudicates my case after I file suit?
If the agency decides your case after you file, the mandamus case typically becomes moot. You may still be able to recover attorney fees in some circumstances if the lawsuit was the catalyst for the agency action.
