What is the B-1 visa?
The B-1 visa is a US nonimmigrant visa for business travelers who do not take up paid employment in the United States. It covers activities such as contract negotiations, client visits, conference attendance, or installing machinery bought abroad — but not employment for a US company. For shorter business trips of up to 90 days, German nationals usually enter visa-free under ESTA; the B-1 visa becomes relevant once the stay is longer or one of the extended activities described in this article is planned.
According to U.S. Citizenship and Immigration Services (USCIS), an initial B-1 stay is typically granted for one to six months, with a maximum admission period of six months per entry. An extension is possible, but the total stay may not exceed one year.
ESTA or B-1: when is visa-free entry enough?
German nationals face no visa requirement, according to IHK Koblenz, when entering for business or leisure purposes and staying no longer than 90 days. In that case, the electronic travel authorization ESTA (Visa Waiver Program, VWP) is sufficient. As the U.S. Department of State states: "Admission with Electronic System for Travel Authorization (ESTA) approval allows for the same activities as contemplated for a B-1 visa holder admitted in that status." In substance, ESTA holders may carry out the same business activities as B-1 visa holders — the difference lies purely in the maximum length of stay and the application process.
A B-1 visa becomes necessary once any of the following applies: the stay exceeds 90 days, the planned activity does not fit within the ESTA framework (e.g. because it goes beyond pure business-trip activities), or the traveler otherwise fails to meet ESTA requirements (e.g. no biometric passport, not eligible for the Visa Waiver Program). In practice, according to IHK Koblenz, the B-1 visa is mainly used for business visits longer than three but no more than six months.
Activities allowed on a B-1 visa
The legal basis for allowable B-1 activities is 9 FAM 402.2-5(B) through (F) of the US Foreign Affairs Manual. According to the corresponding U.S. Department of State fact sheet, these include in particular:
- Commercial transactions that do not involve gainful employment in the US (e.g. taking orders for goods manufactured abroad)
- Contract negotiations and consultations with business associates
- Participation in scientific, educational, professional or business conventions, conferences or seminars
- Independent research
- Litigation
- Installing, servicing or repairing commercial or industrial equipment purchased from a company outside the US — including training US personnel on that equipment (9 FAM 402.2-5(E)(1))
- Specialized trainers transferring knowledge on proprietary techniques or processes, provided the know-how is not widely available in the US (9 FAM 402.2-5(E)(2); the visa is annotated "B-1 SPECIALIZED TRAINER")
The combined B-1/B-2 visa is also common when business and personal travel purposes are linked (e.g. a vacation following a conference) — according to IHK Koblenz, this is the most frequent case for German business travelers.
What is not allowed on a B-1 visa
The central principle emphasized by the U.S. Department of State: "Engaging in business using a B-1 visa entails business activities other than the performance of skilled or unskilled labor. Thus, the issuance of a B-1 visa is not appropriate for applicants who intend to obtain and engage in employment while in the United States." Anyone intending to actually take up a job or work for a US company needs a petition-based work visa such as H-1B or L-1, not a B-1.
Payment from a US source is also excluded: under 9 FAM 402.2-5(F)(1), a B-1 holder may not receive a salary from a US company. Only expense allowances or reimbursement for reasonable travel, lodging and living costs are permitted. The IHK's practical example illustrates this: if a German employee installs a machine bought in Germany at the US subsidiary, payment must come exclusively from the German employer — not from the US entity.
Validity, length of stay and extension
According to USCIS, entry is typically granted for a stay of one to six months, with a maximum admission period of six months per entry. An extension is possible via Form I-539 filed with USCIS, but the total stay may not exceed one year. If the authorized period is exceeded, the traveler is considered "out of status" according to the U.S. Department of State — the visa is automatically voided (Section 222(g) of the Immigration and Nationality Act), and future visa applications may be affected.
If travel purposes change during the stay — for example due to a job offer — a change of status through USCIS is possible without first leaving the United States. However, a new visa in the appropriate category is required for the next entry after departing following a status change.
Applying: DS-160, interview and fee
The application is filed via the online Form DS-160 with the U.S. Department of State, followed by a personal interview at the responsible U.S. Embassy or Consulate. The current application fee is 185 USD, according to the U.S. Department of State. The passport must remain valid for at least six months beyond the planned stay. Applicants should have evidence of the purpose of travel, intent to return to Germany, and ability to cover travel costs — a letter of invitation is not required according to the U.S. Department of State, but IHK Koblenz nonetheless recommends a cover letter from the employer (purpose, duration, confirmation that no US salary is paid) as a practical tip to avoid questions at the port of entry.
B-1, ESTA and work visas compared
| Feature | ESTA (VWP) | B-1 visa | H-1B / L-1 (work visa) |
|---|---|---|---|
| Maximum length of stay | 90 days | up to 6 months, extension up to 1 year total | multi-year, renewable |
| Application | online, no interview | DS-160 + in-person interview | employer petition with USCIS |
| Fee | low (ESTA fee) | 185 USD | significantly higher, employer-paid |
| Employment in the US | not permitted | not permitted | permitted (tied to petition) |
| Typical use case | short business trip/vacation | longer business trip, installation/training, board meetings | local employment, intra-company transfer |
What this means for companies
For companies sending employees on business trips to the US, distinguishing correctly between ESTA, B-1 and petition-based work visas is essential to avoid violating US entry rules — misjudging the category can lead to denial of entry or automatic voiding of the visa. Tools like premote help capture travel purpose, length of stay and the right visa category per trip, and automatically track deadlines such as the 90-day ESTA limit or the 6-month B-1 limit.
FAQ
Do I need a B-1 visa for a short business trip to the US?
Not necessarily. For stays of up to 90 days, German nationals can generally enter visa-free under ESTA — the same business activities are allowed as with a B-1 visa.
Can I work in the US on a B-1 visa?
No. The B-1 visa does not permit employment or salary from a US source. Only expense allowances and reimbursement from the foreign employer are allowed.
How long is a B-1 visa valid?
Entry is usually granted for one to six months, with a maximum of six months per entry. An extension via Form I-539 is possible, but the total stay may not exceed one year.
What happens if I overstay the authorized period?
The visa is automatically voided (Section 222(g) INA), the stay is considered "out of status," and future US visa applications may be affected as a result.
Can I install machinery in the US on a B-1 visa?
Yes, if the machinery was purchased outside the US and payment comes exclusively from the foreign employer — not from the US entity.
