How do you actually know whether you need a visa, an electronic travel authorization, or nothing at all?

Most people ask one question before a trip: “do I need a visa?” If the answer is no, they stop checking. That used to be a reasonable place to stop. It isn’t anymore — a growing number of countries now require a paid, pre-travel authorization even from travellers whose passports are genuinely visa-free.

Here’s the actual framework: three questions, in order, and the second one is the one most people skip.

This is a general framework for how these systems typically work, not a rules database and not immigration advice. Requirements are set by your nationality and the destination, both of which we can’t know for you — check the official source before you book.

The three questions

1. Is my passport visa-free for this destination at all?
2. If visa-free, does the destination still require an electronic travel authorization?
3. Even fully clear on both, are there other conditions that could still stop me?

Question 1: Is my passport visa-free for this destination?

This is the question everyone already asks, so it’s the fastest to answer and the one with the least room for surprise. Your nationality and your destination together determine the baseline: either you’re visa-free for short stays, or you need to apply for a traditional visa in advance.

If you need a visa, the rest of this framework matters less — the visa application itself will tell you what else is required (often including proof of insurance, funds, or an interview). If you’re visa-free, don’t stop here. Move to question 2.

Question 2: Does this destination still require an electronic travel authorization?

This is the question people skip, and it’s the one that’s gotten a lot more likely to apply to you in the last few years.

An electronic travel authorization — often called an eTA, and functionally similar whether it’s branded ESTA, ETA, NZeTA, or (soon) ETIAS — is a lightweight system that sits on top of visa-free access, not instead of it. You fill out a short form online, pay a modest fee, and usually get approved automatically or within a few days. It doesn’t grant the rights a full visa can (longer stays, work authorization), and it doesn’t replace a visa for nationalities that need one — it’s an additional step specifically for people who are already visa-exempt.

The reason this question deserves its own step: this list of countries keeps growing, and a passport that was paperwork-free on your last trip may not be anymore.

Destination	System	Since / status	Typical cost
United States	ESTA	Live since 2009	$21
Canada	eTA	Live since 2016	CAD $7
New Zealand	NZeTA	Live, valid 2 years for most nationalities	NZD $17-23 + levy
Australia	ETA	Live, valid 1 year	AUD $20
Kenya	eTA	Live, valid 90 days, replaced visa-on-arrival	$34
United Kingdom	ETA	Fully enforced for all eligible visa-exempt nationalities since 25 February 2026	£16
EU / Schengen Area	ETIAS	Not yet live as of this writing — see our ETIAS explainer	€20 (planned)

This isn’t an exhaustive list, and it shouldn’t be treated as one — new systems get added, and we’re not going to try to maintain a live global database here (see the sources below for a tracker that does). The point is the pattern: six major destinations already require this even for visa-exempt travellers, a seventh is coming, and the UK’s only went into full enforcement this year. If it’s been a couple of years since your last trip to any of these, don’t assume your last experience still applies.

Question 3: Are there other conditions that could still stop me?

Even with zero visa and zero eTA required, a handful of conditions can still block boarding or entry, and they’re not visa rules at all:

• Passport validity. Many destinations require your passport to be valid for a set period beyond your return date — six months is the most common rule, but it varies. This is an airline check-in issue as much as a border one: airlines are fined for boarding passengers who’ll be refused entry, so they enforce this at the gate.
• Blank pages. Some countries require a minimum number of blank visa pages, separate from the “amendments” pages many passports have.
• Proof of onward or return travel. Common for visa-free and eTA entries alike — some border agents or airlines ask to see it, even if it’s rarely checked in practice.
• Proof of sufficient funds. Less common for eTA-covered destinations, more common for traditional visas.
• Mandatory insurance. Not universal, but real — a Schengen short-stay visa, for example, legally requires travel medical insurance of at least €30,000. This is a visa-specific requirement rather than a general one, and it’s separate from whatever eTA or visa-free status applies. If Europe is your destination, our Schengen visa insurance guide covers which policies actually qualify.

None of these are exotic edge cases — passport validity alone is one of the most common reasons airlines deny boarding, precisely because it has nothing to do with whether you’re “visa-free” and travellers stop checking once they know that part is fine.

How to actually check, for your trip

All three questions depend on your specific nationality and destination — nothing generic, including this article, can give you a final answer. Two official sources cover this reliably:

• The IATA Travel Centre — the same data airlines use to decide whether to let you board, covering visa, eTA, and passport-validity requirements by nationality and route.
• Your destination’s official government immigration or foreign affairs site — authoritative for that country’s specific rules, and the only place that’s guaranteed current when a system like the UK’s ETA changes enforcement dates.

We link both from our visa requirements page rather than keeping our own rules database — a stale answer here risks a missed flight or a refused entry, and that’s not a risk worth taking to save you one extra click.

What this framework deliberately doesn’t do

It doesn’t tell you whether you specifically need a visa, an eTA, or nothing — that depends on your passport and destination, which only an official source can confirm. It doesn’t attempt to be a complete, current list of every eTA system worldwide, because that list changes faster than any article can track it reliably (the Henley & Partners Global Mobility Report maintains a running one). What it does give you: the right three questions to ask, in the right order, so you check the thing you’re most likely to skip — question 2 — instead of stopping at question 1 like most travellers do.
