617.4 Determining the Author’s Citizenship or Domicile for Anonymous and Pseudonymous Works
The applicant should provide the author’s citizenship or domicile, even if the author’s real name is not provided in the application and does not appear on copies or phonorecords of the work.
If the applicant fails to provide this information in an online application, the application will not be accepted by the electronic registration system. If the applicant fails to provide this information on a paper application, the application will be questioned if there is no other basis for establishing that the work is eligible for copyright protection under U.S. copyright law.
For a discussion of anonymous and pseudonymous works, see Sections 615.1 and 615.2.
