I'm planning a trip to Peru this summer, but I don't yet know where I'll go after I leave Peru. The US State Department web site says that proof of onward travel is required when entering Peru:
ENTRY / EXIT REQUIREMENTS: A valid passport is required to enter and depart Peru. Tourists must also provide evidence of return or onward travel.
However, if I visit the site of the Washington DC Embassy of Peru, then follow their Tourism link, the FAQ states, under Was requires visa to enter Peru?[sic], mentions nothing of an onward travel requirement, in
Visas are not necessary for citizens from most countries in the Americas and Western Europe. Citizens of Bolivia, Ecuador and Chile do not need either a passport or a visa to enter certain regions of Peru. Check with the Peruvian consulate in your country for further information. Addresses and telephone numbers are included in the website of the Peruvian Foreign Ministry: www.rree.gob.pe Visitors entering Peru for tourism are granted a 90-day stay, which can be extended by the Immigration Office. Travelers must bear a valid passport or safe-conduct pass issued by Peruvian immigration authorities.
When I visit the web site for the Dallas Peruvian Consulate, I don't find any mention of visa requirements at all.
What are the actual requirements when entering Peru on a U.S. passport? Do I need proof of onward travel, or not?
