B1 Industrial Worker Visa (B-1 After-Sales Service) at a Glance

  • Visa type: B-1 visitor for business used for commercial/industrial after-sales service (a recognised B-1 scenario)
  • Who it’s for: Specialised technicians travelling temporarily to install, service, or repair industrial/commercial equipment purchased from a company outside the U.S., or to train U.S. workers to perform those services
  • Key conditions: The sales contract must require the seller to provide installation/service/training; the equipment must be manufactured outside the U.S.; and the traveller must not receive U.S.-source compensation
  • Why it matters: This is the “safe, defensible” route for sending technicians—because “install/repair” can sound like employment at the border if you arrive under ESTA without the right framing and paperwork

INDEX:

How do I send technicians to the USA?

This route is ideal when you need to send UK technicians to the U.S. to fulfil after-sales obligations linked to equipment delivered to an American customer. Typical use cases include:

  • Installing or commissioning machinery delivered under a sales contract
  • Troubleshooting, warranty repair, maintenance, or upgrades
  • Training the U.S. customer’s staff to operate/maintain the equipment
  • Multi-site client visits across the U.S. for post-sale service work

The common thread: the work supports a foreign-manufactured product sold by a non-U.S. seller, and the technician is temporarily in the U.S. to fulfil the seller’s contractual obligation.

What is the B1 Industrial Worker Visa?

  • Installing or commissioning machinery delivered under a sales contract
  • Troubleshooting, warranty repair, maintenance, or upgrades
  • Training the U.S. customer’s staff to operate/maintain the equipment

ESTA vs B1 visa for technicians: why the B-1 route reduces border risk

Many UK travellers can use the Visa Waiver Program with ESTA for short business visits, but it’s limited to 90 days per trip and is not a visa.

The problem: technicians often answer border questions honestly—“I’m here to install/repair equipment”—and that can be misinterpreted as employment unless the officer quickly sees it fits the B-1 after-sales framework and conditions.

A B-1 visa prepared for after-sales service is often the smarter operational choice because:

  • your purpose is supported by a structured file (contract + letters + evidence) aligned to recognised B-1 rules
  • your case is easier to explain and inspect at arrival (still subject to CBP discretion)

Important accuracy point: A visa can reduce uncertainty, but it does not guarantee entry—CBP always makes the final admission decision at the port of entry.

Permitted activities under the B-1 after-sales service framework

The recognised scope includes:

  • installing, servicing, or repairing commercial/industrial machinery purchased from outside the U.S.
  • training U.S. workers to perform such services

Non-negotiables (where cases fail)

To fit, the officer must be satisfied that:

  • the sales contract specifically requires the seller to provide the services/training
  • the equipment was manufactured outside the United States
  • the technician is not paid by a U.S. source for the services

And this is not a general work authorisation. It’s a narrow, document-driven business visitor scenario.

“Will the visa show what I’m going to do?”

In many technician/service cases, consulates may place an annotation on the visa reflecting the business purpose (for example, after-sales service). The exact wording and whether it references a customer/project can vary by post and case facts. (We design the case so the purpose is clear and consistent across documents and the interview.)

B1 Industrial Worker / After-Sales Service: documents we typically structure

  1. A) Contract & commercial chain
  • Sales contract / PO / SOW showing the seller must provide installation/service/training
  1. B) Letters (the clarity layer)
  • Letter from the UK (or non-U.S.) seller explaining: equipment, contractual obligation, site(s), dates, tasks, and why this technician is essential
  • Confirmation letter from the U.S. customer (recommended): location, project schedule, and acknowledgement of seller-provided after-sales service
  1. C) Technician profile (specialised knowledge)
  • Evidence the technician has product-specific knowledge and is essential to fulfil the contractual obligation
  1. D) Pay & employment
  • Proof salary/remuneration remains outside the U.S. (non-U.S. payroll, assignment letter, etc.)
  1. E) Trip plan (temporary stay)
  • Itinerary, site schedule, return plan, accommodation details

How to apply (UK → USA)

1. Eligibility & risk screening (activity fit + contract fit + compensation structure)
2. Build a consular + border-ready evidence pack aligned to after-sales service rules
3. DS-160 + interview scheduling (as required by the post)
4. Interview preparation: crisp explanations, consistent documents
5. Travel with a “ready to inspect” pack for CBP

Frequently Asked Questions (FAQs)

If the equipment was manufactured outside the U.S., sold under a contract that requires the seller to provide installation/service/training, and the technician is paid from outside the U.S., it may fit the B-1 after-sales service framework.

Some can, but “install/repair” often triggers work-related scrutiny. For real projects, a properly prepared B-1 case is frequently the lower-risk operational choice—while still subject to CBP inspection on arrival.

No, this is a business visitor pathway for a narrow after-sales service scenario, with strict conditions (contract requirement, foreign manufacture, no U.S. pay source).

That’s a red-flag area. We structure the scope carefully and will tell you if the facts point to a different visa solution.
