Business Visitor Access


A Business Visitor is an individual who has business with Fermilab that can be achieved in less than one week while being escorted when in non-public access areas and…

  • Does not require training or a Fermilab ID badge
  • Does not require computing access
  • Does not receive payments or reimbursement using DOE funds


Business Visitors who are coming onsite are encouraged to enter Fermilab through the Batavia Rd. / Warrenville gateBusiness Visitors must go to the Fermilab Welcome and Access Center (located in Aspen East) to get their BV badge. See our Badging Chart for additional information. 

  1. Coordinate with your Fermilab POC the details of your visit.
  2. Fill out the Site Access and Badging form.
  3. Once access is approved:
    • Non-U.S. citizens will be sent an email to complete onboarding in WorkDay. This step must be completed in order for the access request to be fully processed.
    • Onsite visitors will receive an informal letter with a QR Code, which must be presented at the security gate upon arrival.
    • Business visitors are also required to show a valid REAL ID at the security gate
    • Once through the gate, BVs will proceed to the Fermilab Welcome and Access Center to get their BV badge/sticker.
    • In addition to the informal letter, onsite non-U.S. visitors will receive a formal invitation letter that can be used, if needed, in the visa process

*Business Visitors must be escorted when in non-public access areas by a Fermilab-badged individual, unless attending an event is in Wilson Hall and approvals have been obtained for BVs to be unescorted while attending that event.

**Business Visitors must exit the site by sundown unless there is special approval from Security to stay onsite after-hours.

For additional direction on the business visitor process, please refer to the Guidance document and the Security Department website.
