B-1 Category: Business Visitor Visa
The B-1 Business Visitor visas are used by foreign nationals who wish to visit the United States for certain business purposes for a temporary period of time.
If you are seeking the B-1 visa for business purposes, please note that it should only be used for that purpose (making investments, buying goods, attending meetings or seminars) and not for employment purposes.
It is sometimes difficult to draw the line between allowable business activities and illegal employment under the B-1.
