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 would bar non-U.S. citizens from accessing or entering any site or facility owned, operated, or leased by the Department of Energy (DOE), with a narrow exception for certain citizens. Specifically, non-citizens would be prohibited unless they are citizens of Australia, Canada, New Zealand, or the United Kingdom. The prohibition becomes effective 60 days after enactment, and the Secretary of Energy would need to revise regulations and procedures within 60 days to implement the law. In short, the bill tightens access controls to DOE sites by excluding foreign nationals, even for routine or professional visits, unless they come from the four listed countries. The bill raises questions about who is affected (including foreign researchers, students, and contractors who work at DOE facilities), how access would be verified, and how ongoing collaborations and staffing at DOE labs would be handled. It also suggests potential policy tensions with scientific collaboration, international visitors, and current personnel who are not U.S. citizens but may need access to DOE facilities for legitimate work.
