South America entry rules

By the Viamo editorial team · Editor Terje Moy · Last updated July 2026 · 5 min read

South America is one of the world's most rewarding overland-travel regions, and for most Western visitors, the good news is that visas are rarely required for short-stay tourism. The continent's countries have been broadly welcoming to visitors from the UK, US, Canada, Australia and the EU for decades. But the rules differ by country and nationality, some border crossings have their own quirks, and a few countries do charge reciprocal fees — so knowing what to expect before you arrive saves surprises.

The broad picture: most countries, no visa required

For citizens of most Western European countries, the UK, the US, Canada and Australia, the majority of South American countries offer visa-free entry for stays of up to 90 days (and in some cases longer). This makes an overland trip across the continent viable without any advance visa paperwork for eligible nationalities.

Key countries where most Western visitors enter without a visa include:

• Argentina — typically up to 90 days for most Western nationalities
• Chile — typically up to 90 days
• Peru — up to 90 days (extendable once inside the country)
• Colombia — up to 90 days, extendable for an additional 90 under certain conditions
• Ecuador — up to 90 days
• Bolivia — typically up to 90 days (see note below on reciprocity fees)
• Uruguay — up to 90 days for most Western visitors
• Paraguay — up to 90 days for most Western visitors

These figures are general guidance — the exact period and conditions depend on your passport and can change. Always confirm before travel.

Brazil: e-visa for some nationalities

Brazil occupies a position of its own in South America's visa landscape. Citizens of many countries — including the EU, UK and Australia — enter visa-free for up to 90 days. However, Brazil has historically operated reciprocal visa requirements for some nationalities, including the US and Canada, who at various times have needed a visa (or more recently an e-visa) in advance.

Brazil launched an e-visa system for nationals of countries that require one, accessible through the Brazilian government's official portal. The e-visa covers tourism and short business visits. Processing times are generally a few days; apply a week or more before travel. Check the current situation for your passport — Brazil has changed its policy on reciprocity several times and may do so again.

Bolivia: reciprocity fees

Bolivia has historically applied reciprocity visa fees — requiring citizens of countries that charge Bolivian nationals for visas to pay a fee on arrival. This has affected US citizens in particular. The fee structure and whether it remains in place should be confirmed with the Bolivian consulate before travel. Citizens of countries not subject to reciprocity fees typically enter visa-free.

Venezuela: a special case

Venezuela's political and humanitarian situation means that many governments advise against travel, and practical entry logistics are complex. Visa requirements for Venezuela depend on your nationality, but the more immediate question for most travellers is your government's current safety advice for the country. Check your government's travel advisory before making any plans to visit.

The Guianas: Guyana, Suriname and French Guiana

The three Guianas in the northeast of the continent each have their own entry requirements:

• Guyana — British and many Commonwealth citizens have traditionally been visa-exempt; other nationalities should check.
• Suriname — requires a tourist card (toeristenkaart) or visa for many Western nationalities, obtained online or at the border. Check current requirements, as they have changed.
• French Guiana — an overseas territory of France and part of the EU. EU citizens enter freely; other nationalities follow French/EU entry rules, similar to entering metropolitan France.

Crossing land borders

South America's overland crossings are a fundamental part of the backpacker and slow-travel experience — the route from Colombia through Ecuador, Peru, Bolivia and into Argentina or Chile is one of the world's classic overlanding journeys. A few things to know about land crossings:

• Exit stamps matter. You usually need an exit stamp from the country you're leaving before entry stamps in the next are valid. Don't skip the exit formalities, even at informal crossings.
• Tourism tax (reciprocity fee) on entry — a few countries collect a fee at land borders; check in advance whether your crossing collects this.
• Yellow fever vaccination — some countries (including Brazil, Peru, Bolivia and others) require proof of yellow fever vaccination, particularly if you are arriving from certain other countries in the region. Carry your International Certificate of Vaccination (yellow card) — see the World Health Organization guidance on required vaccinations for specific countries.

Extending your stay

In countries where the standard visa-free stay is 90 days, it is sometimes possible to extend your stay by visiting an immigration office (migraciones) and applying before your initial stay expires. Peru and Colombia, in particular, have relatively clear extension processes. Some travellers exit to a neighbouring country and re-enter for a fresh allowance — this works in some cases and at some borders, but should not be assumed to always succeed; immigration officers in some countries have become more aware of repeated border crossings.

Frequently asked questions

Do I need a visa for Argentina and Chile?

Citizens of most Western European, North American and Australasian countries can enter both Argentina and Chile without a visa for tourist stays, typically up to 90 days. Confirm your nationality's specific allowance before travel as it can vary and may have changed.

Do US citizens need a visa for any South American countries?

US citizens have historically needed either a visa or to pay a reciprocity fee for some South American countries, most notably Brazil (at times requiring an e-visa) and Bolivia (a reciprocity fee at some points in recent history). This has changed multiple times; always check the current requirement for your passport.

Do I need a yellow fever vaccination for South America?

Yellow fever vaccination is required or recommended for parts of several South American countries, and some countries require proof if you are arriving from high-risk areas. Carry your International Certificate of Vaccination and check the World Health Organization's current requirements for each country you plan to visit.

Can I travel overland across the whole continent?

Yes. Overland travel from Colombia to the tip of Patagonia is one of the world's great adventures, entirely feasible by bus (and in parts by train or boat). The one gap is the Darién Gap between Panama and Colombia — there is no road, so most travellers take a flight or boat around this section.
