The Users' Office was founded in 1989 and is the portal for CERN's guest scientists coming to work as Users (USER), Cooperation Associates (COAS) and Visiting Scientists (VISC).
The day-to-day work of the the Users' Office Staff covers a wide range of activities.
Newcomers register here, fill in and receive their contracts and residence papers and get advice. Registration is of course only one part of the administrative business. The Users' Office staff handles a large number of electronic requests such as pre-registration, contract modification and extension.
The Users’ Office provides the information and link to ACCU, the Advisory Committee of CERN Users.
Together with the larger experiment secretariats, the Users' Office is responsible for the maintenance of the data in the Grey Book, database of the research programm at CERN.
