U.S. copyright law (Title 17, Code § 105) states that government works (including writings, images, videos, and computer code) prepared by an officer or employee of the United States Government as part of that person’s official duties are deemed to be part of the public domain. Therefore, government works are generally not subject to copyright in the U.S. and unless the work falls under an exception, anyone may, without restriction under U.S. copyright laws:
Use of appropriate byline, photo, and image credits is required. Use of trademarked names and/or visual identifiers to identify unaltered government content or links to government web sites are allowable uses. Permission is not required to display unaltered products which include the trademarked names or visual identifiers as part of the original product. Neither the name nor visual identifier may be used, however, in a manner that implies an endorsement or affiliation with the United States federal, state or local governments or any affiliated agencies.
