When a citizen of another country wishes to travel to the United States for
business or pleasure, there are specific visas that are available for those individuals. The B-1, Business visa is for those interested in traveling to the U.S. to consult with business associates, to attend conventions/conferences, and to negotiate a contract, etc. In other words, the B-1 visa is intended for those applicants traveling to the U.S. temporarily for business related purposes. The B-2, Pleasure/Visitor/Tourist visa is for those who plan to travel to the U.S. for recreational purposes including tourism, to visit with friends and family, and to obtain medical treatment, etc.
When changing status to B-1 Business visitor, it is important that the applicant document the business activity to be performed, the exact length of time needed to complete the business activity, and the applicant’s intent to depart the United States at that time. This documentation may be established by submitting an itinerary, a brochure of scheduled business events, or evidence of a roundtrip airline ticket, etc. This change of status can only be granted for up to 364 days, so it is extremely important to carefully document the exact length of time needed to complete the activity.
