In accordance with the CERN Staff Rules and Regulations, your social insurance cover is the responsability of your employer or of the educational institution at which you are normally enrolled.
If you do not have this kind of insurance covering you in both Switzerland and France, you are under the strict obligation to take the necessary measures to safeguard yourself against the economic consequences of illness, accidents and disability throughout your stay at CERN.
This obligation also applies to any family members who may be accompanying you.
Given that the Organization is located on the border between France and Switzerland, we strongly recommend that you contact the relevant consulates for information on the entry conditions applicable to you in these two countries.
If you require an invitation letter for a visa, please contact Alexia.Augier@cern.ch
