The NDRB is a component of the Secretary of the Navy Council of Review Boards and has its offices located in the NCR. The NDRB conducts documentary reviews and personal appearance reviews in the NCR and, on a traveling basis, at selected sites within the 48 contiguous states. Regional site selection is predicated on the number of pending applications accumulated from a given geographical area and the resources available to support distant personal appearance reviews. The NDRB does not maintain facilities other than at its NCR offices. The primary sites of NCR are: Chicago, IL; Dallas, TX; and San Francisco, CA.
