Visas: A
valid passport is required to enter and depart Peru. Tourists must also provide
evidence of return or onward travel. U.S. citizens may enter Peru for
short-term tourist- or business-related visits of up to 90 days. Health risks: Peru has several provinces in a continuous declared
state of emergency due to leftist rebels, & drug narcotics gangs, & those are
the biggest health risks to be concerned about.
