Petitions for Review are a type of federal litigation commonly used in immigration law to challenge decisions made by administrative agencies, such as the Board of Immigration Appeals (BIA) or the U.S. Citizenship and Immigration Services (USCIS). When individuals or organizations are dissatisfied with the outcome of their immigration case at the administrative level, they may seek review of the decision by filing a petition for review in a federal appellate court.

Motions to reconsider are legal requests made to a court asking it to review its decision based on new evidence, legal arguments, or errors in the original decision. In the context of federal immigration litigation, individuals or parties may file motions to reconsider with the immigration court or the Board of Immigration Appeals (BIA) to seek a review or reversal of a decision.

The Administrative Procedure Act (APA) is a federal statute that governs the process by which federal administrative agencies propose and establish regulations, conduct hearings, and adjudicate disputes. In the context of federal immigration litigation, the APA may be invoked to challenge actions or decisions taken by immigration agencies, such as the Board of Immigration Appeals (BIA) or the U.S. Citizenship and Immigration Services (USCIS).

Mandamus is a legal remedy available in federal litigation that allows individuals to seek a court order compelling a government official or agency to perform a specific act or duty required by law. In the context of immigration law, mandamus may be used to compel action by immigration authorities when they have unreasonably delayed or failed to act on a pending application, petition, or other request.
