There are many different types of activities that are permissible as a Business Visitor in the U.S. However, the line between which activities are allowable and which activities require a work permit is not always clear. Especially with a business presence in the U.S, it is always important to fully understand when and where you cross the line into work permit territory. This not only gives you the ability to explain to an officer how you fall into the business visitor category to protect yourself but it also gives you a realistic list of benchmarks you know you need to accomplish before you can file for a work permit or status of any kind.
