B-1 visas and ESTA travel authorizations both allow short-term business visits to the United States. But they are not interchangeable. Using the wrong entry route—or failing to document activities properly—can trigger costly enforcement, delays, and reputational damage.
The B-1 visa is issued at a U.S. consulate and can cover limited, temporary business activities. Under 9 FAM 402.2-5(E), visitors may install, service, or train others on equipment purchased abroad, or provide after-sales support tied to a foreign purchase.

The B-2 visa is for tourism, visiting family, or receiving medical treatment in the U.S. It is also issued at a U.S. consulate.

B-2 vs. ESTA (Visa Waiver Program):
ESTA is not a visa. It is an electronic travel authorization that allows eligible nationals of participating countries to apply for admission under the Visa Waiver Program (VWP). If admitted, the traveler is placed in VWP status—not B status—for a maximum stay of 90 days per trip. ESTA authorization itself is valid for 2 years (or until passport expiration), allowing multiple entries. Some activities may overlap with B-1 allowances, but VWP admission lacks the documentation, flexibility, and protections of a B-1 visa stamp.

Not Permitted on ESTA:
U.S. authorities are now coordinating across DHS, DOJ, and DOL to scrutinize ESTA and B-1 use in large or politically sensitive projects. Even when an activity is technically permissible under 9 FAM 402.2-5(E), unclear documentation or perceived U.S. worker displacement can trigger site visits, audits, or raids.
Even seemingly lawful activities—such as installation or training tied to foreign-purchased equipment—can cause problems if:
Example: One highly publicized incident involved the government raid of the Hyundai electric battery plant project in Georgia, where foreign technicians reportedly entered under ESTA to install proprietary machinery. While such work may fall within B-1/ESTA allowances, the lack of a visa record and unclear documentation triggered a full-scale government raid, project delays, and global publicity.
THE LESSON: Even when the law allows certain activities, choosing VWP/ESTA instead of a B-1 visa—or failing to document the purpose—can cause major disruption.
For projects that go beyond narrow B-1 allowances, other visas may be more appropriate:
Kennedy Law advises companies on choosing the right visa, preparing documentation, and avoiding costly mistakes.
Because ESTA/VWP admission creates no visa record of your business purpose, cannot be extended or changed, and provides no protection if CBP or ICE disagrees. For complex projects, a properly annotated B-1 visa is the safer route.
