Researchers have introduced ImmigrationReason, a new dataset designed to facilitate legal reasoning research within the domain of U.S. immigration appeals. This dataset comprises over 12,000 decisions from the USCIS Administrative Appeals Office, covering the period from 2005 to 2026. It includes detailed information on legal frameworks, evidence findings, adjudicator criticisms, and final outcomes, with a focus on identifying legal errors and analyzing adjudication processes. The dataset's creation involved advanced AI models like Claude and Opus 4.7 for transcription and quality validation, and it is made available through platforms such as Hugging Face. AI
