The E-2 Investor Visa allows an individual to enter and work inside of the United States based on an investment he or she will be controlling, while inside the United States. This visa must generally be renewed every two years, but there is no limit to how many times one can renew. The investment must be “substantial.“
The E-2 visa allows businesspeople from certain countries to work in the U.S. for a business in which they invest.
The E-2 visa is a nonimmigrant visa, meaning it is temporary, while green cards are permanent. Moreover, a green card through investment requires a dollar investment of $500,000 or more, while an E-2 visa has no dollar minimum set in law.
