B Visa vs ESTA: Which One Do You Actually Need for the US?

For most first-time US travellers the question is simple: apply for ESTA, or apply for a visa? Get it wrong either way and it costs you. Assume ESTA covers something it doesn't, and CBP can turn you back at the border. Miss that a past refusal or an overstay rules ESTA out altogether, and a rushed visa application under deadline pressure is a worse position to be in than starting one early. This guide sets out who qualifies for ESTA, where the line sits with a B1/B2 visa, and what changes the answer.

Who qualifies for ESTA under the Visa Waiver Program

The Visa Waiver Program (VWP) "permits citizens of 42 countries to travel to the United States for business or tourism for stays of up to 90 days without a visa," according to CBP. British passport holders are one of those 42 nationalities.

If you qualify, you apply directly through the official ESTA site, no agent required. An approved ESTA is valid for two years, or until your passport expires, whichever comes first, and it only ever covers business or tourism, never the activities below.

What ESTA doesn't cover

The VWP has a purpose test built in. It does not permit "study, for credit", "employment", or "work as foreign press, radio, film, journalists" (source: travel.state.gov). A genuine business trip, meetings, negotiating a contract, attending a conference, sits inside the VWP's "business" purpose. Taking up paid work for a US employer, studying towards a US qualification, or working as press does not, whatever passport you're travelling on.

ESTA is also a one-trip decision, not a flexible status once you land. Travellers admitted under the VWP cannot change or extend their status while in the US, and, asylum aside, have no right to appeal a refusal of admission at the border (source: CBP's VWP/ESTA FAQ). If your trip might run past 90 days, or might need a status change once you're there, ESTA is the wrong tool from the outset.

If your ESTA application is refused for one of these reasons, or any other, our guide on what to do if your ESTA is refused covers reapplying and the visa route in more detail.

When a past overstay or refusal rules out ESTA

Two questions on the ESTA form matter more than the rest, because a "yes" to either normally closes off the VWP entirely, not just for this trip.

• "Have you ever stayed in the United States longer than the admission period granted to you by the U.S. government?" The underlying law is blunt on this: a previous VWP entrant "must not have failed to comply with the conditions of any previous admission" (8 U.S.C. § 1187(a)(7)). The question covers any past admission, not only a previous VWP trip, and the statute sets no time limit on how long ago an overstay happened.
• "Have you ever been denied a U.S. visa you applied for with your current or previous passport, or have you ever been refused admission to the United States or withdrawn your application for admission at a U.S. port of entry?" (source: ESTA application). A past refusal here usually means applying for a visa again rather than trying ESTA.

If either applies to you, the practical route in is a B1/B2 visa from a US embassy or consulate, applied for directly. CBP is direct about the consequence of an ESTA refusal generally: "If an ESTA application is denied and the traveler wishes to continue with the trip, the traveler will be required to apply for a nonimmigrant visa at a U.S. Embassy or Consulate," and a denial "is not a determination of eligibility for a visa" (source: CBP FAQ).

Two nationality-based restrictions sit alongside this and rule ESTA out regardless of your own history: dual nationality with certain countries, and travel to certain countries after set dates. If either might apply to you, our guide on which passport to use as a dual citizen covers both in detail.

ESTA vs B1/B2 visa: cost and timing compared

ESTA costs $40.27 per application: a $10.27 processing fee, plus $30.00 (a $17 travel promotion fee and a $13 General Fund fee) that only becomes payable if you're approved (verified September 2026; source: ESTA application, fee structure confirmed in the Federal Register notice setting the current fee). There's no interview. CBP recommends applying as soon as you start planning travel and checking your status before booking flights, since some applications need further review.

B1/B2 visa costs $185, non-refundable regardless of outcome (verified September 2026; source: travel.state.gov). It means completing Form DS-160 online, and, since 1 October 2025, "all nonimmigrant visa applicants… will generally require an in-person interview" with a consular officer (source: travel.state.gov). The main exception is renewing a B1/B2 "within 12 months of the prior visa's expiration when the prior visa was issued for full validity at the time of issuance and the applicant was at least 18 years old". Outside that exception, budget for an interview slot on top of the processing time, since appointment availability varies by location and season.

If you already hold a valid US visa, you don't need ESTA at all: "Individuals traveling on valid visas are not required to apply for a travel authorization" (source: CBP FAQ).

One reassurance if you've seen headlines about visa bonds: the bond scheme that now requires some B1/B2 applicants to post up to $20,000 before a visa is issued applies to nationals of specific non-VWP countries. It doesn't touch ESTA-eligible travellers. Our article on the visa bond programme has the detail if a member of your travel party holds an affected nationality.

The short version

• Business or tourism, under 90 days, no disqualifying history: ESTA, applied for directly at esta.cbp.dhs.gov.
• Paid work, study for credit, or journalism assignments: ESTA doesn't cover it, whatever the length of stay.
• A past overstay, a past US visa refusal, or a stay that might run over 90 days: a B1/B2 visa, not ESTA.
• Touring performers and crew: a different route again. See our guide to visas for UK bands touring the US.

This is general guidance, not legal advice, and CBP officers still make the final admissibility decision at the border whichever route you take.
