Lawrence Livermore National Laboratory

Planning Your Visit to the User Resource

To visit the User Resource, an investigator should first contact the User Resource Director or Administrative Contact to discuss the reason for the intended visit, determine suitable dates for the visit, and to provide the names, nationalities, research affiliation/institution of all persons in the visiting party. As the User Resource is located within Lawrence Livermore National Laboratory (LLNL), a national laboratory with controlled access, all visitors must obtain approval to enter the main site. For U.S. citizens, the approval process can usually be obtained within 24 hours of providing the relevant information. For non-U.S. citizens, the visitor approval process can take up to eight weeks. When visiting, all visitors must check into the Westgate Badge Office to pick up badges before entering LLNL’s main site. Investigators must bring suitable identification to the Badge Office to be granted admission to the site. For U.S. citizens, a valid U.S. driver's license or other form of official photo identification is sufficient, and for foreign nationals, a Permanent Resident Card or a valid passport with all required accompanying documentation (e.g., visa) is necessary.
