At present, the Register of Copyrights is appointed by the Librarian of Congress and answers to that office. H.R. 6028 would break that link. The bill would remove the US Copyright Office from the Library of Congress‘s supervisory authority. The Register would instead be nominated by the President and confirmed by the Senate, serving a term of 10 years with the option of reappointment.
