US ESTA in 2026: Who Needs It, the $40 Fee, and How to Apply the Official Way

If you hold a passport from one of the countries in the United States' Visa Waiver Program (VWP), you can visit the US for tourism or business without a visa — but only after you have an approved ESTA, the Electronic System for Travel Authorization. Since 2009 it has been the digital permission that VWP travellers must hold before they board a US-bound flight or cruise. It is quick and cheap compared with a full visa, but it trips people up in two ways: the fee rose sharply in late 2025, and a swarm of copycat websites charge a fat markup for the very same government form.

Who is eligible for an ESTA

ESTA is available only to citizens of the 42 countries in the Visa Waiver Program. That list covers most of Western Europe, plus Australia, New Zealand, Japan, South Korea, Singapore, Chile, Israel and Qatar, among others. If your passport is on it, you can apply online and, once approved, visit the US for up to 90 days for tourism, business or transit without setting foot in an embassy.

If your passport is not on the VWP list, ESTA is not an option — you need a full US visa, applied for through a US embassy or consulate. This is exactly the situation for Nepali passport holders: Nepal is not a Visa Waiver Program country, so a Nepali traveller heading to the US applies for a B-1/B-2 visitor visa, attends an interview and pays a higher fee. ESTA is the shortcut reserved for VWP nationals only.

ESTA is not a visa — and does not guarantee entry

This is the single most misunderstood point. An ESTA is a travel authorization that screens your eligibility to board under the VWP; it is not a visa and it is not a promise of admission. As US Customs and Border Protection puts it, ESTA "does not guarantee entry to the United States" — officers at the port of entry make the final call. The practical difference between the two routes looks like this:

How to apply — the official way

1. Go to the official site only: esta.cbp.dhs.gov, or the official CBP mobile app. This is the only place that issues a genuine ESTA.
2. Have your passport ready. Apply with the passport you will actually travel on — the ESTA is linked to that document's chip, so a new passport means a new application.
3. Answer the questions and pay. You fill in personal, passport and travel details, answer the eligibility questions, and pay the fee by card.
4. Apply early. Approvals are often near-instant, but CBP advises applying at least 72 hours before travel in case a case needs review.

Why this matters if Nepal is on your itinerary

Plenty of our trekkers come from VWP countries — the UK, Germany, Australia, Japan, South Korea — and route through a US airport, or tack a US stopover onto a longer trip. If your journey passes through US border control, you need that approved ESTA before you fly, even in transit. It is a separate, easily-forgotten step from your Nepal paperwork, where entry is far simpler: most nationalities get a Nepal visa on arrival in Kathmandu. For a fuller picture of how 2026's entry rules are shifting worldwide, see our roundup of the 2026 entry-rule changes across ETIAS, the UK ETA and US ESTA, and our dedicated UK ETA 2026 guide.

Once the authorizations are sorted, the mountains are the easy part. If a Himalayan trek is the reason you are crossing time zones at all, our guided Everest Base Camp and Annapurna Circuit itineraries handle the Nepal-side permits and logistics for you — so the only forms you sweat over are the ones back home.
