A business visa is required if an individual is planning business-related travel to the United States on a temporary basis. This is true of most countries, and the important part of this type of visa is that it is granted on a temporary basis only. You will need to state your intention and purpose for the business travel to the given country you hope to visit, as well as the duration of your stay. Under immigration law, it is essential to obtain a business visa to conduct business in a given country. Business visitor visas are often under great scrutiny by a given country because a government wants to ensure that there is no intention on the part of the holder to stay on a more permanent basis.
