Every Country Has Its Own Requirements: Here's How to Check Them
There is no single list of "travel requirements" valid for the entire world: each country sets its own entry rules, and those rules change depending on your nationality, the purpose of the trip, and, in some cases, your previous itinerary. That's why the same person may need a visa for one country and be exempt in the neighboring one.
In this Travel Requirements section we explain the general rules that apply in most destinations (passport, vaccines, customs, luggage, immigration, restrictions), but the specific visa details—who needs it and how to apply—depend on each country.
For that level of detail, check the Visas section of Viaje365, where we break down the most relevant visa requirements country by country regardless of your nationality or language, or always check the official embassy or consulate of your destination as the definitive source.
Why Requirements Vary So Much Between Countries
Entry requirements depend on bilateral or regional agreements between countries, internal immigration policies, health and security conditions, and, in some cases, reciprocity (if country A requires a visa from citizens of country B, country B may require the same in return).
What Factors Change Your Specific Situation
- Your nationality (the passport you carry, not the country where you live).
- The purpose of the trip (tourism, business, study, work).
- Whether you hold dual nationality, since you can choose the most convenient passport.
- Your previous itinerary, if it includes layovers or visits to health risk areas.
How to Check the Official, Up-to-Date Requirement
The most reliable source is always the embassy or consulate of the destination country, or its official immigration/foreign affairs website. Avoid relying solely on forums or social media posts, since requirements can change without notice.

Frequently Asked Questions
Why Do I Need a Visa for a Country If My Travel Companion Doesn't?
Because the requirement depends on the nationality of the passport, not on where you live or where the flight departs from; each nationality has different agreements with each country.
Where Can I Find the Exact Requirement for My Destination Country?
On the official website of that country's embassy or consulate, or in the Visas section of Viaje365 for the most searched destinations.
Can Entry Requirements Change From One Year to the Next?
Yes, they change frequently due to bilateral agreements, immigration policies, or health situations, so you should always verify them before each trip, not just the first time.
Can Dual Nationality Help Me Avoid a Visa?
In some cases, yes, if the other passport you hold has better agreements with the destination country; it's worth comparing both before booking the trip.
