Under this code the Bureau is composed of three (3) structural units namely: the Office of the Commissioner, the Board of Commissioners, and the Board of Special Inquiry. These groups act as collegial bodies and exercises quasi-judicial powers affecting the entry and stay of foreign nationals in the country.

The main objective of the National Bureau of Investigation is the establishment and maintenance of a modern, effective and efficient investigative service and research agency for the purpose of implementing fully principal functions provided under Republic Act No. 157, as amended.

The Bureau of Corrections (BuCor) is charged with custody and rehabilitation of national offenders, that is, those sentenced to serve a term of imprisonment of more than three (3) years.
