Which document serves as the formal record of an investigation?

• A. Report of Investigation
• B. Warrant for Arrest of Alien
• C. Order to Detain or Release Alien
• D. Warrant of Removal/ Deportation

Answer: (A)

The main concept here is understanding what constitutes the formal written record of an investigation. The formal record is the Report of Investigation because it centrally documents all aspects of the investigative process—what was looked into, who was interviewed, what evidence was gathered, what analysis was performed, and what conclusions and recommendations arose. This document creates an official trail that can be reviewed later by supervisors or other authorities to understand why certain actions were taken or not taken. The other options are action-oriented documents that authorize or implement steps (arrest, detention, or removal) but do not themselves serve as the complete formal record of how the investigation was conducted and what it found.
