Please notify the Site Office by submitting a Visitor Pass Request before 3:00 p.m. on the day before the expected visit. Include the name(s) of any visitors, the time you expect them, and your name and contact information.

Please note: Owing to heightened security measures at Berkeley Lab, all visitors must be able to provide picture identification at the entrance to the laboratory. Visitors from outside the U.S. should be prepared to show a valid passport.
