How to Check Visa Requirements for Any Country

"Do I need a visa?" sounds like a yes-or-no question. In practice, the answer depends on which passport you hold, how long you're staying, why you're traveling, and sometimes even which airport you're changing planes in.

Get it wrong and the consequences show up at the worst possible moment: at the check-in desk, when an airline refuses to board you, or at passport control on arrival.

This guide explains the main types of entry permission, where to check the rules for your passport, and the lesser-known requirements that catch travelers out even when they have the right visa.

Why your passport changes the answer

Entry rules are set by the country you're visiting, and they're set nationality by nationality. Two people on the same flight can face completely different requirements.

The gap between passports is large. In the October 2026 edition of the Henley Passport Index, Singapore's passport ranked first, with access to 193 destinations without a visa arranged in advance. At the other end of the index, several passports give that kind of access to fewer than 60.

A few things follow from this:

Check by the passport you'll actually travel on. If you hold two nationalities, the rules can differ for each, and many countries expect you to enter and leave on the same passport.
Your residence doesn't usually count. Living in a country doesn't give you its citizens' visa-free access. A few countries make exceptions for residence permit holders, but don't assume it.
Rules change. Countries add and remove visa requirements as diplomatic relations shift. Brazil, for example, reintroduced visa requirements for US, Canadian and Australian citizens in April 2025. Check the rules for every trip, even to a country you've visited before.

The main types of entry permission

Most destinations fall into one of these categories for a given passport:

Visa-free entry. You can enter for a limited stay, typically for tourism, without applying in advance. "Visa-free" doesn't mean "unlimited": there's usually a maximum stay, such as 30, 60 or 90 days.
Electronic travel authorization. Not technically a visa, but you still must apply online before you travel. Examples include the US ESTA, Canada's eTA and the UK ETA. Europe's ETIAS will work the same way once it launches, though as of October 2026 the EU has not set a start date; our guide to EES, ETIAS and the UK ETA covers the details.
eVisa. A full visa that you apply for and receive online, usually as a document to print or show on your phone.
Visa on arrival. You get the visa at the airport or border, usually after paying a fee and showing documents. Queues can be long, and some countries are moving these to online systems.
Embassy visa. You apply in advance through an embassy, consulate or visa center, often with an appointment, supporting documents and processing time of several weeks.

Each type also covers specific purposes. A tourist entry usually doesn't allow you to work, and some countries treat business meetings, remote work, volunteering or study differently from tourism.

Where to check official visa rules

Use official sources first. Good places to check:

Your own government's travel advice. The US State Department's country pages have an "Entry, Exit and Visa Requirements" section, and the UK FCDO's foreign travel advice has an "Entry requirements" page for each country. These are written for their own citizens, so they're most useful if you hold that passport.
The destination's official immigration or foreign ministry website. This is the authority that actually sets the rules, and it's the only place to get the authoritative version.
The destination's embassy or consulate in your country. Especially useful for embassy visas and unusual situations.
Your airline. Airlines check your documents before boarding because they can face penalties for carrying passengers who don't meet entry rules, so their entry requirement pages are worth a look before you fly.

Beware of lookalike sites. Search results for visas and travel authorizations often include third-party sites that charge extra fees, and some are outright scams. Apply through the official government portal, and check the web address carefully before you pay.

Passport rules that catch travelers out

Even with the right visa, these requirements can get you turned away:

Passport validity. Many countries require your passport to be valid for a set period beyond your trip, often six months. The Schengen Area requires at least three months of validity beyond your planned departure from the Schengen countries. Check your expiry date before you book.
Passport age. For the Schengen Area, your passport must also have been issued within the past 10 years. Some older passports were issued with extra months added, so a passport can look valid by its expiry date and still be refused.
Blank pages. Some countries require one or two blank pages for entry stamps or visa stickers. The amendment or endorsement pages at the back of some passports don't count.
Proof of onward travel. Some countries, and many airlines, ask for proof that you'll leave, such as a return or onward ticket. Travelers on one-way tickets are most often caught by this at check-in.
Funds and accommodation. Border officers can ask where you're staying and whether you can support yourself during the stay.
Stay limits. Visa-free stays have limits, and overstaying can bring fines, deportation or a ban on future entry. In the Schengen Area, the limit is 90 days in any 180-day period across all Schengen countries combined, not per country.

Don't forget transit

If you're changing planes in a third country, check its rules too. Some countries require certain nationalities to hold a transit visa even if they never leave the airport. Others have no international transit area at all. The United States, for example, has no airside transit, so most foreign travelers need an ESTA or a visa even to change planes there.

Self-transfer itineraries need extra care. If you booked separate tickets and must collect your bags and check in again, you'll usually need to pass through immigration, which means meeting the full entry requirements for that country.

A quick visa checklist

Check the rules for the exact passport you'll travel on.
Confirm the type of permission you need, and whether it covers your purpose of travel.
Apply through official government portals only, and leave plenty of time.
Check your passport's expiry date, issue date and blank pages against your destination's rules.
Have proof of onward travel and accommodation ready.
Check every transit country on your route.
Know your maximum stay, and count your days.
Recheck the rules shortly before you leave, because they change.
