Start with your route, not a general visa list
Entry requirements depend on your passport, where you are going, why you are travelling and how long you intend to stay. A rule that applies to a short holiday may not apply to remote work, study or an extended visit. Requirements can also change, so treat travel articles and forum posts as prompts for questions rather than final answers.
Write out your itinerary country by country, including places where you change planes, cross by land or return later in the trip. For each stop, check the destination government’s immigration or consular guidance for your nationality and purpose of travel. If the wording is unclear, ask the relevant embassy or consulate before making a booking that depends on a particular answer.
Check your passport and permission to enter
Look at your passport’s expiry date and condition well before departure. Some destinations or transport providers may expect a period of validity beyond your planned stay, and a damaged passport can cause problems even when it has not expired. Check whether blank pages are needed for stamps or visas, and confirm that the name on every flight booking matches your travel document.
For each country, find out whether you need a visa, an electronic authorisation, an arrival form or no advance permission for your planned visit. Note any limits on length of stay and whether an entry permits a later return. Do not assume that leaving a country briefly resets an allowance. If you hold more than one passport, check which one you will use for bookings and at each border; the rules may differ between them.
Allow time for applications that require an appointment, payment or supporting paperwork. Save confirmation details somewhere you can access without mobile data, while keeping the original document or approved digital record available in the form requested by the issuing authority.
Include transit stops and the way you cross borders
A connection on the way to South America may have its own transit requirements, even if you do not plan to leave the airport. Check every airport on your route, including stops added by a separate ticket. On separate bookings, you may need to collect baggage, check in again and pass through immigration, which can change the documents you need.
Overland travel deserves the same attention. Confirm that your intended crossing is open to travellers using your documents and that your chosen transport will take you through the required exit and entry procedures. At a border, make sure your departure from one country and arrival in the next are recorded as required. Keep any entry receipt or other document you are told to retain until you leave.
An onward ticket, proof of accommodation or evidence that you can support your stay may be requested in some circumstances. Check the official requirements and your carrier’s document guidance rather than assuming a flexible itinerary will be accepted without questions.
Prepare for circumstances beyond a standard holiday
Travelling with children, carrying a passport issued by a country different from your place of residence, or visiting for work can add requirements. A child travelling with one parent or another adult, for example, may need additional documentation depending on the countries involved. Check the rules for your specific situation and allow time to obtain any documents before departure.
Review official health-entry requirements for each destination and transit point, especially if your route includes areas with different rules. This is separate from seeking personalised travel-health advice about your itinerary. Also check any customs declarations or restrictions relevant to what you plan to carry, such as equipment, medication or food. Entry permission does not necessarily mean every item in your bag can cross the border.
Make a final document check before you leave
Create a simple checklist with one line for each country and transit stop: passport validity, entry permission, permitted stay, onward-travel evidence and any additional documents. Keep accessible copies of your passport details, bookings and approvals, stored securely and separately from the originals. Copies can help you retrieve information, but they do not replace documents a border official requires you to present.
Recheck official guidance and your airline’s requirements shortly before travel, including for any route changes. Leave room in your plans for an application delay or a question at check-in. Border officials make entry decisions, so the most useful preparation is to know which rules apply to your own journey and have the documents to support it.
