Travelers' passports should be valid for at least six months beyond their departure date. When arriving by air, US citizens must show a return ticket or an open-jaw onward ticket.
Upon arrival, immigration officials may only stamp 30 days into a passport though the limit is 180 days. If this happens, explain how many more days you need, supported by an exit ticket for onward or return travel.
Bribery (known colloquially as coima) is illegal, but some officials may try to procure extra ‘fees’ at land borders.
Visas are generally not required for travelers entering Peru.
Tourists are permitted a 183-day, nonextendable stay, stamped into passports and onto a tourist card called a Tarjeta Andina de Migración (Andean Immigration Card). Keep it – it must be returned upon exiting the country. If you will need it, request the full amount of time to the immigration officer at the point of entry, since they have a tendency to issue 30- or 90-day stays.
Those who enter Peru via the Lima airport or cruise ship do not receive a tourist card; their visits are processed online.
If you lose your tourist card, visit the Oficina de Migraciónes or obtain a replacement copy via the website. Information in English can be found online. Extensions are no longer officially available.
Anyone who plans to work, attend school or reside in Peru for any length of time must obtain a visa in advance. Do this through the Peruvian embassy or consulate in your home country.
Carry your passport and tourist card on your person at all times, especially in remote areas (it’s required by law on the Inca Trail). For security, make a photocopy of both documents and keep them in a separate place from the originals.
