The E-2 Treaty Investor Visa offers a flexible, indefinitely renewable option for entrepreneurs and corporate executives who hold citizenship in one of the 80+ nations maintaining an active treaty of commerce and navigation with the United States. Unlike the EB-5, there is no legally mandated minimum dollar threshold under US law; instead, the regulations require a ‘substantial’ capital injection — typically ranging from USD 80,000 to over USD 300,000 depending on the industry — that must be irrevocably committed and placed at genuine commercial risk in a real, operating, for-profit enterprise. To satisfy consular standards, the business cannot be ‘marginal’, meaning it must possess a credible five-year business plan proving its capacity to generate significant economic impact and revenue well beyond merely supporting the investor’s basic living expenses. The primary applicant must hold at least 50% ownership or clear operational control to actively develop and direct the venture. While it does not automatically transition into a green card and requires an intent to depart when the business concludes, it allows spouses full open-market work authorisation and permits children under 21 to reside and study in the United States.
