This new agreement replaces the old agreement between the United States of America and the Swiss Confederation on Social Security, signed on 18 July 1979, and the supplementary agreement signed on 1 June 1988. The competent authorities and agencies of the contracting states assist each other in the implementation of this agreement, within the framework of their respective authorities. This assistance is free, subject to the exceptions that must be agreed in an administrative agreement. From 19 June 2017, it will be possible to obtain a guarantee certificate for a worker posted from China to Switzerland or to remain in the Old Age, Survival and Disability Pension Insurance (OASI/DI) for the duration of his secondment. The maximum booking period is 72 months. An exceptional extension beyond 72 months is only possible if the social security authorities concerned reach an agreement. The guarantee certificate you receive from one country indicates the effective date of your exemption from paying social security contributions in the other country. In general, this is the start date of your temporary transfer to the other country or the start date of your self-employment. To avoid any difficulties, your employer (or you, if you are self-employed) should apply for a coverage certificate as soon as possible, preferably before starting your work in the other country.
Workers already posted to Switzerland by their Chinese employers before the agreement comes into force must present a certificate of coverage to the relevant Chinese authorities within three months of the entry into force of the SSA in order to remain in their national social security system. This warranty certificate is valid as soon as the SSA is registered. This table is just a guide. For more information on U.S. benefits, visit the Social Security website at www.socialsecurity.gov.
