To prohibit persons who are not citizens of the United States, except for those from the "Five Eyes", from accessing or entering Department of Energy sites and facilities.

This bill prohibits non-U.S. citizens from accessing or entering Department of Energy (DOE) sites and facilities, with an exception for citizens of Australia, Canada, New Zealand, or the United Kingdom (the "Five Eyes" alliance). It requires the Secretary of Energy to update relevant regulations within 60 days of enactment to implement the restriction. The prohibition takes effect 60 days after the bill becomes law. This directly affects foreign nationals seeking access to DOE facilities, excluding those from the specified allied countries.
