Peru is one of the easiest countries in South America for Americans to enter. There is no visa to apply for, no pre-arrival form to fill in, and no health paperwork left over from the pandemic. For a two-week trip, the entire requirement is a valid passport and a return ticket.
Where travelers get caught out is in the details: how long you are actually allowed to stay, which is not what most guides say, what happens if you plan to extend, and the rules for anyone travelling with children or holding two passports.
This guide covers what you need for the trip, what the immigration officer will and will not do at the desk, and the handful of situations where Peru’s rules are genuinely more restrictive than they first appear.
💡 Planning the trip itself? Entry is the easy part. The parts worth planning are altitude sequencing, permits that sell out months ahead, and the internal flights that hold the itinerary together. Explore our 10-day Peru tours or let our team build an itinerary around your dates.

No. U.S. passport holders receive tourist entry authorization on arrival, whether you land at Jorge Chávez International Airport in Lima or cross at an official land border. There is nothing to apply for in advance and no visa on arrival to pay for.
This is the part that is most often reported inaccurately, so it is worth being precise.
The legal maximum is 183 days within a rolling 365-day period, and in practice most visa-exempt travelers are admitted for up to 90 days within a 180-day period.
What you will actually get is whatever the immigration officer decides, and 90 days is the routine stamp. The officer has discretion to grant anywhere from 30 days upward.
What you cannot count on is making up the difference later. Since the 2023 modification of the Foreigner Law, extensions of tourist stays are restricted in practice to nationals of Andean Community countries, meaning Bolivia, Colombia and Ecuador. As an American, if you are stamped for 90 days, you should plan on 90 days.
The practical takeaway: if you intend to stay longer than three months, say so politely at the desk and ask for the time you need, before the stamp goes in. Once you have walked away from the counter, your options are limited. And check the stamp or your digital record straight away rather than assuming.
If you stay past your authorized period, you pay a daily fine calculated against Peru’s official tax unit, settled when you leave. Serious immigration problems can also carry re-entry bans measured in years. Neither is a catastrophe if you catch it early, but both are entirely avoidable by reading your entry date on the way in rather than on the way out.

Your passport must be valid for at least six months beyond your arrival date. Airlines check this at check-in in the United States and will deny boarding, which means the rule bites long before you reach Peruvian immigration. If yours expires within seven or eight months of your travel dates, renew it before you book anything else.
You need at least two blank pages in the visa section for entry and exit stamps. This is easy to overlook on a well-used passport, and it is a real refusal reason.
Peru has fully digitalized the Tarjeta Andina de Migración. There are no paper slips to complete on the plane and no receipt to keep safe for two weeks.
That last point is worth money. Hotels can zero-rate the tax for non-resident foreign guests, and some will ask for evidence of your entry to apply it.
Airline check-in agents and immigration officers can both ask for evidence that you intend to leave within your authorized stay. A return flight or an onward ticket out of Peru, printed or on your phone, settles it. This is asked for more often at U.S. check-in desks than at Peruvian immigration.
The authorization granted at the border is single entry. If your itinerary crosses into Bolivia for Lake Titicaca or into Chile, coming back into Peru is a fresh entry, assessed again. Nothing about your first stamp carries over, so plan the days accordingly.
Peruvian procedures for minors are stricter than most travelers expect, and most guides skip this entirely.
According to the U.S. Department of State, U.S. citizen minors under 18 travelling to Peru alone or with only one parent do not usually require additional documentation if they are entering as tourists and staying under 183 days. That covers the overwhelming majority of family holidays.
Two situations are different:
Both require an Autorización de Viaje para Menores de Edad, a travel authorization completed by the non-travelling parent at a Peruvian notary, or at a Peruvian consulate in the United States as a Permiso Notarial de Viaje. It is valid for 30 days and one trip only, so it is timed rather than filed early.
Regardless of which case applies, carry a copy of each child’s birth certificate and, when only one parent is travelling, a notarized consent letter from the other. Airlines request these more often than immigration does.
If you hold both U.S. and Peruvian citizenship, Peru expects you to enter and exit on your Peruvian passport. This changes several things at once: the tourist day limits do not apply to you in the same way, the minor authorization rules above are triggered for your children, and the hotel tax exemption for foreign visitors does not. If this is your situation, check with a Peruvian consulate before travelling rather than relying on general tourist guidance.

Currency. The Peruvian sol (PEN). U.S. dollars are widely accepted in Lima, Cusco and the Sacred Valley for hotels, tours and larger purchases, but bills must be clean and undamaged. A small tear or a pen mark is enough for a merchant or exchange house to refuse a note, and this genuinely happens.
Cards and cash. Visa and Mastercard work in hotels and better restaurants. Beyond that, carry soles in small denominations, particularly for markets, artisans, taxis and rural areas. Withdraw in Cusco or Lima rather than in small towns, where ATMs run out during high season.
Declaring cash. Amounts over US$10,000, counted across your whole party, must be declared on entry. Do not treat this as a formality that nobody checks.
No vaccinations are legally required to enter Peru when arriving directly from the United States. Several are strongly recommended:
Speak to a travel clinic six to eight weeks before departure, since some of these need lead time to take effect.
COVID-19. All entry restrictions have been lifted. No vaccination certificate, no test, no health affidavit.

Altitude is the health issue that actually affects most visitors, not anything at the border. Cusco sits at 11,152 ft (3,400 m), and arriving there directly from sea level is what ruins the first two days of many trips. The fix is itinerary order rather than medication, and our guide to preventing altitude sickness in Peru sets out the sequence that works.
On insurance, one point specific to American travelers that most Peru guides omit entirely: Original Medicare does not cover healthcare received outside the United States, and Part D does not cover prescriptions bought abroad. Some Medigap plans include a foreign travel emergency benefit covering 80% of emergency care with a lifetime cap, but that is a partial backstop rather than coverage.
Buy a standalone travel policy, and make sure it explicitly includes emergency medical evacuation from high altitude. Evacuation from the Sacred Valley or a jungle lodge is not a taxi ride, and it is the line item that justifies the premium. If anyone in your party has a pre-existing condition, most insurers require purchase within a set window of your first trip deposit.

Peru is a welcoming country for visitors and the ordinary precautions are the ordinary ones. In Lima and Cusco, petty theft and phone snatching happen in crowded markets and on busy streets. Keep valuables out of sight, do not wear obvious jewellery, and use ride-hailing apps or hotel-arranged taxis rather than flagging cars at night. Our guide to whether Peru is safe covers the picture region by region.
If your passport is lost or stolen, report it to the police immediately and keep the report. You will need to apply for a replacement at the U.S. Embassy in Lima in order to leave the country, and immigration may ask for the police report on departure. Build in time: this is not a same-day fix.
Electricity. 220 volts at 60 Hz, with Type A sockets that accept standard U.S. flat-pin plugs and Type C round-pin sockets. Laptops, phones and camera chargers are almost always dual voltage and need nothing more than the plug shape. High-draw heating appliances such as hair straighteners and curling irons are the exception and will need a converter, not just an adapter.
Flights. Lima is served nonstop from Miami, Houston, Atlanta, Newark, JFK, Los Angeles, Dallas and Fort Lauderdale, with most arrivals landing late at night. Our guide to flights from the USA to Peru covers gateways, connection times and how to sequence the domestic leg to Cusco.
Time zone. Peru does not observe daylight saving, so it matches U.S. Eastern Time for part of the year and sits an hour behind for the rest. Jet lag is minimal from the East Coast.
No, U.S. citizens do not need a visa to enter Peru for tourism. American passport holders are granted visa-free entry on arrival, provided their passport is valid for at least six months beyond the arrival date and has blank pages available for entry and exit stamps.
The legal maximum is 183 days within a rolling 365-day period, but immigration officers routinely grant 90 days, and that is what most American visitors receive. The officer decides at the desk, so if you need longer, ask before the stamp goes in and check what you were given.
In practice, no. Since the 2023 reform of the Foreigner Law, tourist extensions are effectively restricted to nationals of Bolivia, Colombia and Ecuador. Americans stamped for 90 days should plan on 90 days, because topping up to the 183-day legal maximum from inside the country is not realistically available.
Your airline will most likely deny boarding at check-in in the United States, before Peruvian immigration ever sees the passport. The six-month rule is applied by carriers as well as by border authorities, so renew well ahead rather than arriving and hoping for discretion.
U.S. citizen minors entering as tourists for less than 183 days do not usually need extra documentation, even when travelling with only one parent. Dual U.S.-Peruvian children entering on a Peruvian passport, and stays beyond 183 days, require an Autorización de Viaje, valid for 30 days and one trip.
No. Peru has fully digitalized the Andean Migration Card, so there are no paper forms to complete on the plane. Entry is recorded when your passport is scanned, and you can download the digital TAM record from the Migraciones portal if a hotel needs it for the tax exemption.
No vaccinations are legally required for entry from the United States, but hepatitis A, typhoid and routine immunizations are strongly recommended for all travelers. Yellow fever is recommended for jungle areas below about 2,300 m, including Puerto Maldonado and Iquitos. Visit a travel clinic six to eight weeks ahead.
Original Medicare does not cover healthcare outside the United States, and Part D does not cover prescriptions purchased abroad. Buy a standalone travel medical policy that explicitly includes emergency evacuation from high altitude, which is the coverage that actually matters on an Andean itinerary.
Yes, but your original entry authorization is single entry, so returning means a fresh assessment and a new stamp from a different officer. Days from your first entry do not carry over, and the officer applies the same discretion again, so do not assume continuity across the border.
Amounts over US$10,000, counted across everyone travelling together, must be declared to customs on arrival. Below that there is no declaration requirement, though carrying large amounts of cash is inadvisable in any case given card acceptance in the main tourist centres.
Report it to the local police immediately and keep a copy of the report, then apply for a replacement passport at the U.S. Embassy in Lima. You cannot leave the country without one, and immigration may ask to see the police report when you depart, so allow several days.
Entry to Peru is genuinely straightforward, and once the passport and the return ticket are sorted, the planning that matters is everything after the airport: the altitude sequence, the permits that sell out months ahead, and the internal flights that hold it all together. Tell us your dates and who is travelling, and we will build the itinerary around them. Start with a custom itinerary shaped to your pace.
