E2 Visa grants a person who has a great number of funds to invest to enter America for the sole purpose of setting up a business. However, this visa does not give you permanent residency but one advantage of the E2 visa is that you can be extended if the business is still viable. The investor can either invest in a new or existing company, but the company can not be used to make a job only for an individual investor. The investor must employ at least 3-5 others to qualify.
