The Vienna Conventions provide that, in general, nationals of a country who work abroad
            in the diplomatic or consular services of their country are exempt from social security
            coverage and contributions under the host country's laws, unless the host country
            specifically waives that exemption.
         
         The Conventions, to which both the United States and Switzerland are parties, apply
            to:
         
         
            -

                     members of the staff of a diplomatic or consular mission, including the diplomatic,
                        consular, administrative and technical staffs;
