Peru is a country of basically free access. Most of the countries of America and Western Europe do not require a tourist visa to enter Peru, and the maximum length of stay granted by the authorities is 183 days (it can not be extended). For a stay for a longer period with other objectives (business, study, work, etc.) it is necessary to previously request the corresponding visa to the Peruvian consulates.
To enter Peru, it is an essential requirement to present a valid passport. Citizens of Argentina, Brazil, Paraguay, Uruguay, Ecuador, Colombia, Bolivia, Venezuela and Chile can enter with their national identification document.
