In Chile, foreign workers that have the "technical" quality, as defined by Chilean law, are not required to pay contributions to Social Security.
For this exemption to apply, the law establishes the following rules:
Workers must be "technical", at least. "Technical Workers" are defined as those who have knowledge of a certain science or art that can be proven by documents that show professional or specialized studies. Of course, these documents must be legalized and, if necessary, translated by the Foreign Relations Ministry.
The worker must be affiliated to a foreign Social Security system that covers at least sickness, disability, old age, and death. This can be proven by a certificate from the foreign Social Security institution that the worker belongs to, properly legalized, that shows coverage of this benefits, and can be also applied to workers that are already receiving a pension.
