ESTA for business trips: what you can negotiate in America

You fly to America to see a customer, negotiate for two days, walk a trade show and sign the framework agreement on Friday. You don't need a visa for that. ESTA is enough, as long as you do business in America and don't work there. That exact distinction is where European business travelers trip up, rarely out of bad intent, but because the difference barely shows in an entrepreneur's day-to-day. This article draws the line the way the law, the State Department's Foreign Affairs Manual and the guidance of the border agency CBP draw it.

1What ESTA is on a business trip, and what it isn't

ESTA stands for Electronic System for Travel Authorization. It isn't a visa but the electronic authorization to travel to the USA by air or sea under the Visa Waiver Program. The program covers 42 countries, including most of Europe. The underlying law is short and clear: anyone entering under the Visa Waiver Program is applying for admission as a visitor under INA 101(a)(15)(B), the same category as a holder of a B-1 or B-2 visitor visa, for no more than 90 days.

That gives you the most important rule for any business trip: on ESTA you may do what a business visitor may do, and nothing more. ESTA is not a mini work visa, and it's no license for everything that isn't expressly forbidden. The authorization only says you may travel. Whether you may enter is decided by the CBP officer at the airport, and CBP itself states that an approved travel authorization does not guarantee entry.

Two conditions make the program stricter for business travelers than a visa. By entering, you waive any review of the decision made at the border, and you can neither extend nor change your status inside the USA. If you realize after 80 days that the project will take longer, you have no way to fix that on the spot. The key facts are in the table below.

2The basic rule: business yes, work no

The State Department sums up the line in one sentence: business in the B-1 sense generally means activities that are not skilled or unskilled labor. The clearest legal test comes from an old decision, Matter of Hira. A tailor took measurements in the USA for suits that were made abroad and then shipped. That was permitted because the principal place of business and the place where the profit accrued were abroad. Almost every permitted activity follows this idea: what you do in America serves a business that is essentially run outside the USA.

From this you get three test questions you can answer before every trip:

• Who pays you? Your salary or fee must not come from a US source. A US partner may, however, reimburse reasonable travel and living expenses: flights, hotel, meals and similar basic costs.
• Where is the value created? If you negotiate a contract your company carries out at home, the value stays abroad. If you carry out the contract in the USA, you are working there.
• Are you replacing an employee? If a US company would otherwise have to hire or engage someone for the task, it's no longer a visitor activity.

CBP puts it just as briefly in its guidance on permitted B-1 activities: business activities are generally allowed as long as you receive no pay from a US employer or US company. CBP then lists what that means: negotiating contracts, consulting with business associates, attending board meetings of a US corporation, litigating, attending conferences and seminars, and doing independent research.

3Permitted activities at a glance

The Foreign Affairs Manual lists the classic business purposes in 9 FAM 402.2-5(B). You enter as a business visitor if you conclude commercial transactions that don't amount to gainful employment in the USA, for example as a merchant taking orders for goods made abroad. The same applies if you negotiate contracts, consult with business associates, litigate, attend scientific, professional or business conventions, conferences and seminars, or do independent research.

For European entrepreneurs, that means in practice: the sales director discussing terms with a distributor in Texas is a visitor. The managing director checking quality and negotiating volumes at a supplier in Ohio is a visitor. The founder talking to investors about a stake is a visitor. The Manual expressly allows you to look for and evaluate investments, including one that later qualifies for an E-2 investor visa. But it draws the same line as everywhere else: no productive work and no active management of the business while you're a visitor.

If you sit on the board of a US corporation, you may enter for its meetings and carry out the duties that come with the seat. CBP goes a step further: an outside board member who is paid for their time and travel costs may attend the meeting as a visitor. And if you only want to tour a business to learn how things are done there, that's allowed too, as long as you observe and don't pitch in.

The table below sorts the activities clients mention to us most often. It doesn't replace a case-by-case review, but it shows how the authorities draw the line.

4What you cannot do on ESTA

The prohibitions follow the same logic. If you do productive work in the US for a US client, get paid there or fill a job, you are not a visitor. That holds whether the activity lasts a few days or several weeks.

4.1Setting up your own US branch

For many business owners, this is the most surprising limit. Asked whether a visitor may come to a new branch, subsidiary or affiliate of their foreign employer to set it up or work there, CBP gives a clear no and points to the L-1. Discussing the setup, looking for office space and meeting attorneys, accountants and banks count as consulting with business associates. Running the branch, training staff and managing day-to-day operations is work. If that is your plan, the route is the L-1 visa if a company at home can send you, or the E-2 if you invest in your own US company.

4.2Building, installing, repairing without the right basis

Construction work is off limits for visitors, on the building site and in the workshop alike. That is what 8 CFR 214.2(b)(5) says. If you supervise or instruct others on construction work without doing it yourself, however, you can enter as a visitor. Installing, servicing and repairing machinery bought abroad falls under a separate, narrowly drawn rule with conditions on the purchase contract. It matters so much to mid-sized European manufacturers that we have given it its own article: B-1 for installation, service and training.

4.3Paid services for US clients

A consultant who spends a week in an American client's office delivering a project and then invoices for it is performing the service in the US. That is no longer consulting with business associates; it is the service itself. The same goes for trainers, designers, programmers and tradespeople. There is one exception for lectures at universities and similar institutions: the law lets visitors accept an honorarium for usual academic activities if they last no more than nine days at any one institution and you have not been paid by more than five institutions in the previous six months.

4.4What the law rules out in principle

The visitor category excludes study, as well as working as a representative of foreign press, radio or film media. And if you enter on a B-2 visitor visa for personal purposes, you may not do B-1 business. On ESTA the question does not arise, because the program covers both purposes; that makes it all the more important to state the purpose that is true when you enter.

5Gray areas: trade shows, client visits, talks and your own US company

Most of the questions we get are not clear-cut cases but activities somewhere in between. Four come up especially often.

The trade show booth. Attending a trade show is a classic business purpose. Staffing your own booth is more narrowly defined: CBP considers it permissible if you work for a foreign exhibitor and your duties are mainly abroad. A field sales rep from Stuttgart advising customers at his employer's booth fits that picture. A booth hostess hired by a US agency does not.

The demo at the client's site. Presenting a product, showing how it works and answering questions is part of selling. Once the demo turns into commissioning, training the client's staff or a repair, you leave the scope of a business trip and end up under the rules for installation and service.

The laptop in the hotel. Reading email on a business trip and calling your office at home is part of doing business. But neither the law nor the Foreign Affairs Manual has an exception for doing your regular job from the US for weeks. The authorities ask whether you are coming as a visitor or to work, and a trip whose purpose is working on your laptop does not look like a visit to a border officer. Our position on this is in the box below.

Your own US company. Many of our clients set up a US company before they have a visa. As an owner you may enter for meetings with your bank, accountant and business partners, attend meetings and make the decisions an owner makes. What you may not do: run the company on site, serve customers yourself or deliver goods yourself. The Foreign Affairs Manual explicitly names actively managing the business as the limit for investors. For anything beyond that, there is the E-2, the L-1 or, for trade with the US, the E-1 treaty trader visa.

6When ESTA is not enough: B-1 visa or work visa

A B-1 visitor visa essentially allows the same business activities as ESTA. But it is worth having in three situations. First, if you are excluded from the Visa Waiver Program: for example after a stay in Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria or Yemen since March 1, 2011, as a dual national of Iran, Iraq, North Korea, Sudan or Syria, after a visit to Cuba since January 12, 2021, or if your ESTA was denied. Second, if 90 days are not enough, because a visitor with a visa can be admitted for up to a year and extended. Third, if your activity falls into one of the special categories of the Foreign Affairs Manual that the consulate annotates on the visa, such as a specialized trainer or B-1 in lieu of H. An ESTA cannot carry such an annotation.

If you are ESTA-eligible, read the trade-offs in our overview ESTA and the B-1 visa before applying for a B-1. The ESTA application asks whether you have ever been refused a US visa, so a refusal follows you into every future ESTA application. If you want to work in the US, run a branch or stay longer, you do not need a better visitor visa; you need a work visa. The table below maps the typical plans.

7Mistakes that cost business travelers their ESTA

We see these mistakes again and again. None of them is dramatic, but any one can end a trip before it starts.

Miscounting the 90 days. A side trip to Canada, Mexico or a Caribbean island does not reset the clock. When you come back, you are only readmitted for the rest of the original 90 days. If you overstay the 90 days, you violate the terms of your admission, and the law then bars you from the program. Only if an emergency prevents you from leaving can the authorities grant a period of up to 30 days.

Forgetting the ESTA after getting a new passport. The authorization is tied to your passport. A new passport, a new name, a different nationality or a changed answer to one of the yes/no questions all require a new application. Your existing ESTA, on the other hand, only has to be valid on the day you arrive, not until you leave.

Applying through an intermediary site. CBP stresses that private sites do not speed anything up and are not affiliated with the government. The fee on the official site is $40.62. Anything an agency charges on top is its markup.

Telling different stories. The ESTA application asks about your current or previous employer; CBP says this helps show you do not intend to immigrate. The form also has a section on your social media accounts. What you enter there, what your profile says and what you say at the counter should match. We have described how entries go wrong in practice in Why Europeans are turned away at the US border and in Five years of social media for an ESTA.

Traveling without documents. The officer wants to know why you are coming, how long you are staying and where you are staying. An invitation, a schedule and a return ticket answer those questions before they become a problem. What exactly to pack and what a good invitation letter looks like is in the US business trip checklist.

When your trips become more frequent, your stays longer and your tasks on site bigger, that is good news for your business and bad news for your ESTA. Then it is time to choose the status that fits your plan instead of squeezing the plan into the status. With us, that starts with the visa roadmap or a consultation.

In short

• ESTA is a travel authorization under the Visa Waiver Program: you enter as a visitor for up to 90 days, and the CBP officer at the airport decides whether to admit you.
• The same business activities are allowed as on a visitor visa: meetings, negotiations, contracts, orders for goods from abroad, trade shows, conferences and board meetings.
• Not allowed: productive work, pay from a US source, setting up a US branch and construction work.
• If you want to stay longer, do installation or training, or run things on site, you need a B-1 visa on the right basis or a work visa such as the L-1, E-1 or E-2.
