Business Travel to the USA: Visa, Preparation & Etiquette

Do I need a visa for a business trip to the USA?

For most short business trips from Germany an ESTA travel authorization under the Visa Waiver Program (VWP) is enough – you do not need a visa, provided you only perform classic business activities (meetings, negotiations, conferences, trade shows) and stay no more than 90 days per visit. Anyone staying longer, who cannot rely on the VWP, or whose planned activity touches on borderline cases applies for a B-1 business visa. What matters is not the occasion but what you actually do: "business" is allowed, "work" is not.

This guide explains which authorization fits your trip, which activities are permitted and which require a work visa, how to prepare for the entry inspection (CBP), and what counts in US business culture. Unsure what applies to you? Our visa check leads you to an assessment in a few steps, and you'll find the matching service packages under services.

ESTA or B-1 visa – which fits my business trip?

Under the VWP, the ESTA covers essentially the same scope of activity as a B-1 visa – just without an embassy appointment and with stays up to 90 days, with no extension or change of status. The B-1 visa is the right choice if you stay longer than 90 days, travel repeatedly on a planned basis, are not VWP-eligible (for example due to certain prior stays in sanctioned countries), or want documented certainty at entry.

We go deeper into duration, application, and requirements in B1/B2 basics and in ESTA or visa?.

A practical tip for deciding: if you cannot say today for certain that your next stay will be under 90 days, or if you enter several times across the year, the multi-year B-1 visa is often the calmer choice – you avoid re-running the ESTA logic for every trip and are better documented in borderline cases. For the classic three-day trip to a client meeting or a trade show, the ESTA is faster, cheaper, and entirely sufficient. Note also: anyone previously refused on a regular visa, or with certain prior stays (e.g. in countries excluded from the VWP), cannot use the ESTA at all and must take the B-1 route anyway.

Important: A valid ESTA or visa is only permission to seek admission. The actual admission – and the permitted length of stay – is decided by the CBP officer at the airport at every entry.

Which business activities are allowed in the USA – and which are not?

This is the most important question of any business trip. The US Department of State and USCIS draw a clear line between permissible "business" (commercial transactions without gainful employment) and impermissible work ("skilled or unskilled labor", "local employment and labor for hire"). The rule of thumb: you may initiate and conduct business for your foreign company – but you may not perform productive work in the US and be paid for it by a US source.

Expressly permitted under ESTA/B-1 are, among others:

• Business meetings, discussions, and consultations with business associates
• Negotiating contracts and contract talks
• Attending conferences, conventions, seminars, and trade shows
• Taking orders for goods manufactured abroad (e.g., as a sales representative)
• Independent research
• Settling an estate / legal matters, appearing as a witness
• Limited after-sales service: installing, servicing, or training on equipment purchased abroad if the sales contract requires it (exception under 9 FAM 402.2; no construction work)

Not permitted (requires a work visa, e.g. H-1B or L-1):

• Physical, "productive" work – such as setting up production equipment, tooling, manufacturing
• Salary or fee from a US source for your activity
• Providing services to US customers for pay
• Employment with a US employer, running the day-to-day business of a US subsidiary, supervising US staff
• Construction work

On compensation: You may not receive a salary from a US source for your activity. The only thing allowed is for a US source to pay you an expense allowance or reimbursement of incidental expenses related to the short stay (travel, hotel). Your salary continues to come from your German employer.

Why is this line so delicate? Because US authorities have stepped up scrutiny here in recent years. The typical borderline cases are rarely obvious: a technician who "just briefly" commissions an already-sold machine at a US customer is only clean on B-1 if the after-sales exception applies – meaning the sales contract calls for exactly that service, the equipment was made abroad, and it is not construction work. A consultant who directs a US team on site for weeks and runs its day-to-day work crosses the line into employment – even if still paid from Germany. And continuing to work "remotely" for your German employer on the laptop while you actually entered as a tourist is likewise a gray area you should not stretch in the wrong visa category. When in doubt: have the activity assessed before the trip, not explained at the counter.

If your planned activity falls in the right-hand column, clarify it before you travel. Our visa check helps with the first assessment; matching packages are under services.

How do I prepare for entry (CBP)?

Even with the correct authorization you must convince the CBP officer that you are coming as a business visitor, not to work, and that you will leave as planned (strong ties to your home country). So prepare documents and carry them in your hand luggage – not in your checked bag.

1. Invitation letter from the US business partner: purpose, duration, locations, and who covers which costs.
2. Confirmation from your own employer in Germany: employment, purpose of travel, and a note that your salary continues to be paid from Germany.
3. Agenda/itinerary for the trip (meetings, conference, trade show) with contact details.
4. Evidence of ties to Germany (employment contract, family, residence) to show intent to return.
5. Business cards, conference/trade show tickets, hotel and return-flight booking.
6. Prepare clear, concise answers to CBP questions: "What is the purpose of your trip?", "How long will you stay?", "Who is paying?", "Will you be working here?". Answer honestly and consistently with your documents.

Describe your purpose as a "business visit" concretely (e.g., "contract negotiation", "conference attendance"), not vaguely as "work". Read more about the inspection process, questions, and customs rules in US entry & customs (CBP).

Tip: Consistency beats completeness. If the invitation letter, agenda, and your verbal answers all line up, inspection usually goes quickly. Contradictions are the most likely cause of secondary questioning.

Expenses, per diem, and travel costs

Travel and accommodation costs are usually paid by your German employer; a US partner may reimburse expenses but may not pay a salary for the activity. For internal accounting the US concept of per diem is useful: daily allowances for lodging and meals that vary strongly by city (New York and San Francisco are well above average). Also budget for tips (see etiquette), roaming/data, local mobility (rental car, rideshare), and sales tax, which in the US is only added at the register. Keep all receipts – German expense accounting requires them, and they also support your business purpose at entry.

US business etiquette: what matters culturally?

German and US business cultures resemble each other in many ways but differ in tone and pace. Knowing the differences makes you appear more assured.

• Punctuality: Be on time; in the US this is taken for granted, though somewhat less rigidly timed than in Germany. Give brief advance notice if you are running late.
• Small talk: US meetings almost always begin with light small talk (travel, weather, sports). Don't skip it – unlike in Germany it is part of building the relationship. Avoid sensitive topics (politics, religion, salary).
• Communication style: US counterparts phrase things in a friendly, optimistic way and emphasize the positive. German directness can come across as blunt; soften criticism diplomatically and don't be irritated by effusive praise.
• Meeting culture: Clear agenda, results and action orientation ("next steps", "action items"), decisions often faster. A crisp presentation is preferred over a long detailed discussion.
• Address and demeanor: Quick move to first names, a handshake with eye contact, a confident but polite manner. Smart business casual is common depending on the industry.
• Tipping in a business context: In US restaurants 18–20% tip is standard (not optional); at a business meal the host pays. Taxis/rideshare, hotel staff, and coat check are also tipped – a clear difference from Germany.
• Follow-up: Promptly (ideally within 24 hours) send a short thank-you email with a summary and agreed next steps. This is expected in the US and underlines professionalism.

Connectivity, conferences, and travel logistics

Sort out connectivity before the trip: an international data plan or a US eSIM is often cheaper than roaming. Check that your corporate VPN, video-conferencing tools, and cloud access work on the road, and bring a travel adapter (US sockets, 110 V). For conferences and trade shows, register in advance, print badge confirmations, and carry plenty of business cards – they are less formal in the US but useful for networking. Watch time zones when scheduling and build in buffers for domestic connections and longer security checks. Travelers with sensitive equipment should know the customs rules we explain in US entry & customs (CBP).

Plan the logistics around the appointment: book a hotel close to the venue, since traffic and distances in large US cities are easily underestimated, and allow generous time for entry on day one – after a long-haul flight comes CBP inspection, often a connecting domestic flight, and jet lag. Don't schedule key meetings for the first hour after arrival. Keep presentations both offline and in the cloud so unstable conference Wi-Fi doesn't slow you down, and always carry travel documents, ID, and a spare charger in your hand luggage. Good travel insurance with international health cover belongs on every US business trip, as medical treatment in the US is very expensive.

Global Entry: time savings for frequent travelers

If you fly to the US several times a year, consider Global Entry – CBP's Trusted Traveler Program for expedited entry. Instead of the regular line you use kiosks or the app, which saves a lot of time on arrival. In 2026 Global Entry costs USD 120 for a five-year membership and includes TSA PreCheck in the US (faster security for domestic flights). It requires a background check and an interview. Important: Global Entry speeds up entry but does not replace an ESTA or visa – you still need those. All application steps are in Global Entry basics.

What does a business-trip authorization cost in 2026?

The ESTA fee has been USD 40.27 since 1 January 2026 (previously USD 40; the jump from 21 to 40 came in 2025 via the One Big Beautiful Bill Act). The authorization is valid for two years. A B-1/B-2 visa costs the MRV application fee of USD 185 (expected to rise to USD 205 on 30 May 2026) plus the Visa Integrity Fee of USD 250 levied since 1 October 2025 – around USD 435 in total. The wait for an appointment at the US missions in Germany (Berlin, Frankfurt, Munich) is usually a few weeks under normal conditions but can vary seasonally. Always check current amounts and wait times on travel.state.gov.
