ENTRY AND EXIT REQUIREMENTS: Visa is not needed for most Western Europeans, US citizens and Australian visitors. When entering the country, visitors receive a 90 day permit renewable for the same period of time. Some must pay the following tax in cash: US Citizens US$100 / Canadians US$ 55 / Australians US$ 35. (Subject to change). Fresh products, plants and animals can't be taken into the country. When entering to Chile it is necessary to fill in a form testifying if one enters with/without fresh products.
The receipt is valid for multiple entries during the validity of the traveler's passport.
In an effort to prevent international child abduction, many governments have initiated procedures at entry/exit points. These often include requiring documentary evidence of relationship and permission for the child's travel from the parent(s) or legal guardian not present.
Dependent children under age 18 (including the children of divorced parents) arriving in Chile alone, with one parent, or in someone else's custody, are required to present a letter notarized before a Chilean consular officer in the United States certifying that both parents agree to their travel. To exit Chile, children traveling under one of these scenarios must present either the notarized letter used to enter the country or a letter of authorization signed before a Chilean notary if executed in Chile. In either case, the document presented must be executed not more than three months prior to entry or departure.
Travelers considering scientific, technical, or mountaineering activities in areas classified as frontier areas are required to obtain authorization from the Chilean government at least 90 days prior to the beginning of the expedition. The portions of Antarctica claimed by Chile are exempt from these pre-approval requirements. Officials at the Torres del Paine National Park require mountain climbers to present an authorization granted by the Frontiers and Border Department, obtainable at the Chilean Embassy or Chilean consulates throughout the United States.
