This may be because it was taken by an employee of the Congress as part of that person’s official duties, or because it has been released into the public domain and posted on the official websites of a member of Congress. As a work of the U.S. federal government, the image is in the public domain.

This signature is believed to be ineligible for copyright and therefore in the public domain because it falls below the required level of originality for copyright protection both in the United States and in the source country (if different). In this case, the source country (e.g. the country of nationality of the signatory) is believed to be 美國.

Note that this tag cannot be used on all signatures, as not all signatures are copyright-free.

See Commons:When to use the PD-signature tag for an explanation of when the tag may be used.
