The E-2 treaty investor visa allows you to stay indefinitely, although the visa must be renewed every few years. Unlike with many other visas, you are not required to state a specific time you plan to return to your home country. All that’s needed is an “intent” to depart from the United States upon the termination of the E2 status. Many people continue to run a successful business in the United States for years and renew their visa several times.
