Documents and Visas.

Travelers coming to Peru usually only need a valid passport and a return ticket (anywhere outside Peru). Please check with the Peruvian government before coming. If you wish to stay more than 90 days, you need to renew your Tourist Card (given to you when you enter the country) and visa (stamped into your passport) in the Direction General de Migrations in Lima (Av. España block 7, Breña, Lima; ph. 330-4111) or the main cities. One thing you have to take in account is to ask for at the moment your tourist card is given to put it for 60 or 90 days, because it is usually given for 30 days. Always carry your passport and tourist card (or a photocopy) when walking by the street or using a public transport in a city.
It is advisable to bring a student card (i.e. ISIC) to save money in places and services like museums, archaeological sites, buses, hotels and hostels. There is no need to have an international vaccination certificate, but if you travel to some areas where a disease is present (i.e. malaria, yellow fever). You will need to be vaccinated before going. You can have this done in most of the major cities. All the foreign embassies and consulates are located in Lima. Peruvian embassies and consulates are found in all the neighboring countries and other countries in the world.
