OBS_VALUE: No licence/authorisation required from firms to enter the market for this sector. Regarding professional practice, Decree Law 2757 and Decree Law 3621 establish that membership to an association is a voluntary and personal act, and therefore no one can be compelled to join in order to be able to practice. However, engineers and technicians graduated abroad, e.g. in computer engineering, and hired in Chile must request authorisation from the Associations of Engineers and Techniciansto be able to work. These professionals will be registered in a special registry that identifies the specific activity they are authorised to perform as well as the duration.
