A checklist of other things to consider:
Most of America and Western Europe countries do not require a tourist visa to enter Perú. The maximum length of stay granted by the authorities is 183 days (it cannot be extended).
For a longer stay or with other objectives (business, study, work, etc.) it is necessary to previously apply for the corresponding visa to the Peruvian consulates.
In any case, to enter Perú, it is an essential to present a valid passport. Citizens of Argentina, Brazil, Paraguay, Uruguay, Ecuador, Colombia, Bolivia, Venezuela and Chile can enter with their national identification document.
For more information, refer to our full section on "Passport, Visa & Permits".
On the home front, make sure all bills are paid or have a means of being paid.
It is best to inform tax offices of any change in residency. Some countries have reciprocal tax agreements, and others may require you to pay some form of taxes both in your home country and abroad.
National Tax Administrations are an excellent resource to know exactly what steps to take when moving away. In Perú, the National Tax Administration Superintendency (SUNAT in Spanish) is the institution in charge of collecting the main taxes. For example, the General Sales Tax (IGV), which is the tax on the value added at each good/transaction made at different stages of the economic cycle.
For more information, refer to our full section on "Taxes".
For concerns about your health when abroad, the World Health Organization (WHO) publishes International Travel and Health, which is revised annually and is available online for free. Another excellent resource is MD Travel Health, which provides free and complete travel-health recommendations for every country, and is updated daily.
Most travellers will need vaccinations for hepatitis A, typhoid fever and yellow fever, as well as medications for possible diarrhea and altitude sickness. Malaria is recommended for all areas below 2,000 m (6561 ft), including the cities of Iquitos and Puerto Maldonado.
These recommendations only apply for Lima, Cusco, and Machu Picchu. If you are planning to visit other destinations or Amazonian areas, you should pay special attention into health and vaccinations requirements. Other immunizations may be necessary depending upon the circumstances of the trip and the medical history of the traveller.
Insect repellent is recommended, in conjunction with other measures to prevent mosquito bites.
It is also recommended to visit either a travel health clinic or a personal physician 4-8 weeks before departure.
Remember that long-term travellers who are under regular treatment may not have access to their medical care during their trip. Therefore, it is advised to bring along enough medications for the entire stay.
