What is the term used for a request to review a decision made by a higher authority?

The correct term for a request to review a decision made by a higher authority is "appeal." In the context of immigration law and various administrative procedures, an appeal is a formal process by which an individual can challenge a decision and seek a review from a higher authority. This higher authority reviews the original decision to determine if there were errors in the application of law or fact, and may consequently reverse or modify the decision.

Understanding the distinction between an appeal and other terms is crucial. A motion to reconsider generally refers to asking the same authority that made the original decision to review its own decision, rather than seeking a higher authority's input. A request for information typically involves seeking additional data or clarification rather than contesting a decision. Reassessment may imply a review of circumstances for various purposes but is not a formalized request for a higher authority to evaluate a previous decision. Therefore, "appeal" best captures the concept of formally asking a higher authority to review a decision.
