Can You Work on an ESTA? Allowed Activities, Remote Work, and Risks

Working on an ESTA is not permitted in the traditional sense: the Visa Waiver Program admits you as a business or tourist visitor, and the same restrictions that apply to B-1 and B-2 visa holders apply to you.¹ You can attend meetings, negotiate contracts, and go to conferences. You cannot take a job, freelance for U.S. clients, or accept pay from a U.S. source. Remote work for a foreign employer sits in a gray zone that depends on who pays you, who benefits from your work, and whether your visit still looks like a visit.

Business Activities That Are Allowed

The legal definition of “business” for immigration purposes covers commercial transactions, negotiations, consultations, conferences, and similar professional activities, as long as they don’t involve gainful employment in the United States.² The underlying principle is that you’re advancing the interests of your foreign employer or your own foreign business, not filling a role in the American labor market.

Under that framework, you can:

Attend scientific, educational, professional, or industry conferences and conventions, whether presenting or observing.
Negotiate contracts and consult with U.S. business partners on ongoing international deals.
Take orders for foreign-made goods, as long as the goods aren’t delivered during the trip and no money changes hands from a U.S. source.¹
Conduct independent research that doesn’t involve compensation from a U.S. entity.
Sit on a corporate board as a foreign-based director attending meetings of a U.S. corporation.
Scout locations for a possible U.S. office or meet with American lawyers about an international deal.

Short-term training is allowed in narrow circumstances. A foreign company that has sold equipment to a U.S. buyer can send someone to install, service, or train American workers on that equipment, but only when the sales contract specifically requires it, the person has specialized knowledge essential to the obligation, and they receive no pay from a U.S. source.¹ Once training becomes the primary purpose of a longer stay, or starts producing value for a U.S. company beyond what’s incidental to the instruction, it crosses into H-3 trainee visa territory.³

What Counts as Prohibited Employment

The regulation draws a bright line: “local employment or labor for hire” is not business.² Unauthorized employment by anyone in B-1 or B-2 status, which includes VWP travelers, is treated as a failure to maintain status under federal law.⁴ The test isn’t whether the work sounds professional. It’s whether you’re providing services that benefit a U.S. entity or filling a role a U.S. worker could fill.

Common scenarios that cross the line:

Working for a U.S. company in any arrangement where an American business directs your daily tasks and benefits from your output, regardless of how you’re paid.
Freelancing, consulting, or taking contract work for U.S. individuals or companies while you’re in the country.
Receiving U.S.-source compensation, whether that’s salary, hourly wages, or non-cash benefits like free housing and meals given in exchange for services.
Building and construction work, which the regulations single out specifically as prohibited local employment, including some supervisory roles.²
Informal exchanges like childcare, house-sitting, or domestic help in return for room and board. Au pair arrangements, for example, are legally treated as employer-employee relationships requiring their own visa.

The part-time or short-term nature of the work doesn’t rescue it. Neither does calling it “volunteer” when you’re receiving something of value in return. Immigration authorities look at the substance of what you’re doing, not the label.

Remote Work for a Foreign Employer

This is where most travelers get confused, and where the law hasn’t fully caught up with how people work now. No statute or regulation directly addresses sitting in a hotel room answering emails for your London-based employer. What exists instead is a patchwork of rules, enforcement patterns, and common-sense boundaries.

The general enforcement posture treats incidental remote work, like checking email, joining a video call, or handling something urgent, as falling within the scope of a tourism visit. A British marketing manager who spends a week in New York and responds to work messages during the trip is unlikely to face scrutiny. The reasoning: no American worker is displaced, no American company benefits, and the compensation comes entirely from abroad.

To stay on the safer side of this line, several factors need to line up:

Your employer is based outside the U.S. and your employment relationship predates the trip.
Your pay goes to a foreign bank account. Deposits into a U.S. account raise questions about domestic economic activity.
None of your clients or work product serves U.S. entities. Coding for a German software company is different from freelancing for an American startup, even on the same laptop.
Tourism or permitted business is the primary purpose of your visit, with the remote work secondary.

The danger zone is treating the U.S. as a remote-work base. Staying close to the 90-day limit, making repeated back-to-back trips, renting a coworking space, or telling a CBP officer that you’re “working remotely from the U.S.” all signal that employment is what’s driving your travel. If an officer concludes you’re effectively living and working in the country, they can deny entry on the spot. Because VWP travelers waive their right to contest removal in most circumstances, there’s very little recourse at that point.⁵

Jobs That Always Need a Different Visa

Some work can’t fit into the business visitor category no matter how brief the trip.

Journalists and Media Workers

Representatives of foreign press, radio, film, or other media outlets need an I visa under 22 CFR § 41.52.⁶ Even if you’re covering a story for a foreign audience and your salary comes from abroad, gathering news or producing media content in the U.S. is classified as work beyond business visitor activities. A journalist attending a press conference as an observer might have an argument. A journalist conducting interviews and filing stories does not.

Athletes and Performers

Professional athletes competing in U.S. events and entertainers performing for American audiences need O or P visas. The P-1A classification covers internationally recognized athletes, and O-1 visas apply to individuals with extraordinary ability performing separately from a group.⁷ The P classification also extends to entertainment groups, reciprocal exchange artists (P-2), and culturally unique performers (P-3).⁸ Turning up at a competition or venue without the right visa is one of the faster ways to get sent home at the border.

Medical Students on Clinical Rotations

Foreign medical students in their third or fourth year can participate in unpaid elective rotations at U.S. medical schools under the business visitor category, but the restrictions are tight. The student cannot receive any pay from the U.S. institution, cannot engage in research, and must be admitted specifically as a business visitor (B-1 or WB status), not as a tourist. Pleasure visitor status is not acceptable for clinical rotations.

Volunteering on an ESTA

Unpaid volunteer work for a recognized religious or nonprofit charitable organization is permitted under specific conditions in the State Department’s Foreign Affairs Manual. You must be a member of and committed to the sponsoring organization, the program must benefit local communities or a charitable cause, and you cannot receive any payment, though the organization can reimburse incidental expenses like meals or transportation. The program cannot involve selling goods or soliciting donations.⁹

You’ll need a letter from the sponsoring organization stating your name, date and place of birth, foreign home address, U.S. destination, and the expected duration of the assignment. Carry it with you when you enter; CBP officers may ask for it. VWP travelers cannot extend the 90-day stay even if the program runs longer.

Taxes Can Apply Even When Immigration Doesn’t Object

Even if the immigration side is clean, the IRS has its own rules. Income from personal services performed while you’re physically inside the United States is generally U.S.-source income, regardless of where your employer is based or where the paycheck lands.

There’s a narrow exemption for nonresident aliens. Income from personal services performed in the U.S. is not treated as U.S.-source income if you meet all three of these conditions: you work for a foreign employer not engaged in U.S. business, you’re present in the U.S. for no more than 90 days during the tax year, and your total pay for those services is $3,000 or less. Miss any one condition and the full amount becomes taxable U.S. income.¹⁰ Most remote workers on a professional salary blow through $3,000 quickly, which means they technically owe U.S. tax on income earned during the stay.

Spend enough time in the country and a bigger problem opens up. Under the IRS substantial presence test, you become a U.S. tax resident if you’re present for at least 31 days in the current year and at least 183 days across a three-year weighted period: all days in the current year, one-third of days in the prior year, and one-sixth of days from two years back.¹¹ Becoming a U.S. tax resident means your worldwide income is subject to American taxation.

What Happens If You Get Caught Working

Consequences for unauthorized employment on an ESTA are severe and compounding. At the border, a CBP officer who suspects you’re entering to work can deny admission and put you on the next flight home. Once inside the country, unauthorized employment is treated as a failure to maintain your immigration status.⁴

The lasting damage comes from the re-entry bars tied to unlawful presence. Accumulate more than 180 days of unlawful presence and leave voluntarily before a year passes, and you’re barred from re-entering for three years. Stay a year or more and the bar jumps to ten years. In the worst cases, particularly re-entry after deportation, the bar becomes permanent, with the earliest possibility of requesting a waiver only after ten years outside the country.¹² These bars don’t just block ESTA travel. They can make you inadmissible for any U.S. visa category.

A violation also effectively ends your VWP eligibility. Even after any formal re-entry bar expires, a prior immigration violation stays in CBP’s systems and makes future ESTA approvals unlikely. Most people in that situation end up applying for a traditional visa at a U.S. consulate, where a consular officer will ask pointed questions about the earlier violation.

At the Border

CBP officers are trained to probe the purpose of your visit, and the questions can feel invasive, especially for business travelers whose trips genuinely straddle the line. A few things that help:

Have a clear, honest explanation of your trip’s purpose. “Attending a trade show and doing some sightseeing” is straightforward. “Working remotely for a few weeks” invites follow-up questions you may not want to answer.
Bring supporting documents. Conference registrations, hotel bookings, return flights, and invitation letters from business contacts show that your trip has a defined purpose and end date.
Keep stays well under 90 days and avoid repeatedly pushing close to the limit, which signals that you may be using the VWP as a substitute for a work visa.
Don’t volunteer information about remote work. You should not lie, but leading with “I plan to work from my Airbnb” frames the entire trip as an employment visit.
Know that your devices can be searched. Officers have the authority to inspect electronic devices at the border, and Slack messages about “working from the U.S. for a few months” can contradict a stated tourism purpose.

If your situation is complicated, for example a freelancer with both U.S. and foreign clients, or someone planning extended remote-work stays, talking to an immigration attorney before the trip is worth the cost. The line between a permissible business visit and unauthorized employment isn’t always obvious, and guessing wrong can reshape your ability to travel to the U.S. for years.
