B-1 Commercial Work
Installation, Service and Repair
Foreign workers traveling to the U.S. to install, service or repair commercial or industrial equipment or machinery sold by a foreign company to a buyer within the U.S. are able to apply for a B-1 Commercial Work Visa. A purchase contract between the two companies and evidence that the foreign worker possesses the specialized knowledge essential to perform the services is necessary.
These provisions do not apply to a foreign worker seeking to perform building or construction work, whether on-site or in-plant. The exception is for an applicant who is applying for a B-1 visa for supervising or training other workers engaged in building or construction work, but not actually performing any such building or construction work.
