The document provides an overview of the requirements and supporting documentation needed for an E visa. The E visa allows nationals from treaty countries to enter the US to direct or develop operations of an enterprise where they have made a substantial financial investment. Requirements include being a national from a treaty country, having control over a substantial investment in an operating commercial enterprise in the US, and entering the country to direct the invested enterprise. Supporting documentation must be provided from both the foreign company where the individual is employed, and the US company where they will work, and include items like articles of incorporation, financial statements, organizational charts, and the individual's resume and job description.
