Site Access Policy

We welcome thousands of visitors to the laboratory every year. Visiting researchers may consult with their host to arrange a gate pass; members of the general public are invited to take a tour or attend one of our OutLoud public lectures.

Argonne National Laboratory is a controlled access facility, and approval for site access is required. All visitors must be pre-authorized before being allowed on the Argonne site.

  • For information regarding site access for a U.S. citizen, contact the Argonne Information Center at (630) 252-5755.
  • Site access for foreign nationals who do not already have site access approval requires the completion of a Visit/Assignment Request (ANL-593) and 7- to 30-day advance notice to process the request. For information, call the Foreign Visit and Assignment Office at (630) 242-1142. The laboratory's site access policy supports its obligation to ensure that classified and sensitive technologies, equipment, and information are controlled in compliance with the applicable regulations.

Important Note Regarding ID Cards

Effective June 1, 2015, per the 2005 REAL ID Act, Argonne National Laboratory cannot accept driver's licenses from the following jurisdictions: American Samoa, Louisiana, Minnesota, New Hampshire, and New York. Argonne will accept alternate forms of photo ID (see list below) for individuals from the identified jurisdictions. This applies only to U.S. citizens; non-U.S. citizens must complete information for the non-U.S. approval process.

Argonne accepts these alternate forms of photo ID.:

  • U.S. passport or passport card
  • Federally issued photo identification, military ID, or other government-issued photo ID cards
  • HSPD-12 card or global entry card
  • Enhanced driver's licenses or enhanced ID cards issued by the states of Minnesota or New York

Foreign Visits and Assignments

Argonne is firmly committed to fulfilling U.S. Department of Energy (DOE) directives and requirements regarding foreign visits and assignments. Unclassified foreign visits and assignments are to be used to advance laboratory program objectives consistent with U.S. foreign and nonproliferation policy, international energy policy and agreements, and national security policy and objectives. Protection of counterintelligence interests, security interests, and sensitive subject information and technologies in a manner consistent with program requirements, including compliance with export laws and regulations, is the responsibility of all employees. Under no circumstances should foreign nationals be allowed on any Argonne site without the appropriate reviews and approvals. Sponsorship of laboratory operations/functions by DOE does not mitigate, supersede, or remove the laboratory's responsibility to adhere to the policy. Contact the Office of Foreign Visits and Assignments at (630) 252-1142 forĀ  information.
