Work permits are required if you wish to take up paid or unpaid employment in Argentina.
Work permits in Argentina are issued to foreigners by the National Directorate of Migration In Argentina. In order for you to obtain a work permit for paid employment you will need to have the company that you will be working for make the application for you.
In some cases work permits can be applied for by the Consulate, usually though this is reserved for volunteers and charity workers.
If you intend to visit Argentina, on holiday, a business trip, to study, work, volunteer or as an emigrant you should get up to date and accurate information from the official website of the National Directorate of Migration.
