A more thorough explanation:

A business visitor is a person who is invited or allowed to enter someone else's property for a purpose related to the owner's or possessor's business. This term can have different meanings depending on the context:

In tort law, a business visitor is someone who is invited or permitted to enter or stay on someone else's property for a reason that is directly or indirectly related to the owner's or possessor's business dealings. For example, a customer who enters a store to buy something is a business visitor. The owner or possessor of the property has a duty to take reasonable care to ensure that the property is safe for business visitors, and can be held liable for injuries or damages that result from their negligence.

In immigration law, a business visitor is a non-U.S. citizen who has a B-1 visa, which allows them to enter the United States for a temporary period of time for business purposes. This can include attending meetings, negotiating contracts, or conducting research. However, a B-1 visa holder is not allowed to work in the United States, except in certain limited circumstances.

An example of a business visitor in tort law would be a customer who enters a store to buy something. The store owner has a duty to ensure that the store is safe for customers, such as by cleaning up spills or fixing broken stairs. If the owner fails to take reasonable care and a customer is injured as a result, the owner could be held liable for the customer's injuries.

An example of a business visitor in immigration law would be a foreign executive who comes to the United States to attend a business conference. The executive would need a B-1 visa to enter the country, and would be allowed to stay for a limited period of time to conduct business activities. However, the executive would not be allowed to work in the United States, such as by taking a job with a U.S. company.
