ETA vs eVisa vs Visa vs Visa-Free in 2026: What the Difference Actually Is

Few things in modern travel are as quietly confusing as the words on the checklist. One country tells you to get an ETA. The next wants an eVisa. A third gives you a visa on arrival, a fourth still wants a sticker in your passport from an embassy, and a fifth waves you straight through visa-free. They sound interchangeable. They are not. Getting the category wrong is how people miss flights, pay a stranger's website twice over, or turn up at a border with the wrong piece of paper. Here is the plain-English map for 2026 — and where Nepal sits on it.

The one that trips everyone up: an ETA is not a visa

The newest category is the electronic travel authorisation, and it causes the most confusion because it looks like a visa and is bought like a visa — yet it is deliberately something else. As Wikipedia's own definition puts it, an ETA is "a midway point between countries allowing a foreign national to travel to their country unconditionally without a visa" and the old world of embassy interviews. In other words, it is a light pre-screening layer bolted onto a visa-waiver relationship. You only need one because your passport was already exempt from needing a visa; the country simply now wants to vet you online first.

That is why the big four are all ETAs, not visas: the US ESTA, Canada's eTA, the UK ETA and the EU's incoming ETIAS. Each is cheap, fast, tied to your passport number, and valid for multiple short trips. None of them is a visa, and none lets you do things a visa allows, such as long stays or work.

eVisa, VOA and the sticker: three flavours of a real visa

Once you actually need a visa, the only question is how you get it. An eVisa is the online version — you fill a form, upload a photo, pay by card and receive an emailed approval before you fly. A visa on arrival is the same legal thing granted at the counter when you land, trading the online lead time for an airport queue. A consular visa is the old-fashioned way: paperwork lodged with an embassy, occasionally an interview, and a sticker in the passport before departure. All three are visas. Which one is offered depends entirely on your nationality and your destination — the same country can hand a Canadian a visa-free stamp and require a full eVisa from a neighbouring passport.

Which one do you actually need?

It comes down to two facts: your passport and your destination. Check the destination's official immigration site for your specific nationality — the same trip can be visa-free for one passport, an ETA for another and a full eVisa for a third. Beware, too, that categories drift: Kenya scrapped its visa on arrival for a compulsory online authorisation, and Europe's ETIAS will soon add a pre-screen for visitors who currently breeze in visa-free. If you are only changing planes, a different rule may apply again — see our guide to transit visas. And whatever the category, mind the clock once you are in: overstaying carries the same fines and bans regardless of how you entered.

Where Nepal sits on the map

Good news for anyone Himalaya-bound: Nepal keeps it simple. Most nationalities get a visa on arrival — a genuine visa issued at Kathmandu's Tribhuvan International Airport (and major land borders), where you fill a short form at a kiosk, pay in US dollars and are stamped in. It is not an ETA and not a pre-flight requirement for most visitors; you sort it when you land. The current tiers and exact fees, plus who is exempt and who must apply in advance, are laid out in our Nepal visa guide. If you want the sharper VOA-versus-online comparison, read visa on arrival vs eVisa.
