The Agreement establishes a general territoriality rule, which states that a worker’s
employment or self-employment is typically subject only to the social security laws
of the country where the work is performed. Under this rule, if a worker’s employment
or self-employment would otherwise be covered by the laws of both countries, coverage
is limited to the system of the country in which the work takes place, and the worker
is exempt from coverage under the other country’s system. However, there are several
exceptions to this rule, designed to ensure that coverage is provided under the system
of the country with which the worker has a substantial connection. These exceptions
are explained in RS 02002.790 - RS 02002.850.
