Peru Entry Requirements for U.S. Citizens (2026)

Entry checklist

• Passport valid 6+ months beyond arrival (enforced)
• Return/onward ticket — often checked at check-in
• No visa, no online forms for tourist stays up to 183 days
• The officer decides your granted days — usually 90-183, state your real itinerary

The 183-day reality

Peru's max is among the world's most generous — but the stamp is what counts, not the legal max. If you need the full 183 (trekking season, remote work), say so clearly at immigration and show onward travel past day 90.

Machu Picchu logistics

Entry tickets to Machu Picchu are timed and limited — book weeks ahead in high season. The classic sequence: fly into Lima → Cusco (acclimatize 1-2 days, it's 11,000 ft) → Sacred Valley or the citadel. Altitude sickness is the real entry requirement nobody lists.

Extension and overstay

Extensions are handled by Migraciones offices — roughly S/16 (~$4) per day overstay fine if you slip past your stamp. Peru is strict on exit: overstay fines are collected at the airport before departure.
