E-2 visas are investor visas for investors from certain countries who have a trade agreement between their home country and the US. Foreign nationals who would wish to apply for an investor visa need to make sure that the amount that they want to invest is substantial, in terms of how much it takes to operate the business and start the business. They need to ensure that the business itself is not marginal, meaning that it’s going to return more than a living wage for the investor and his or her family, and they need to make sure that the amount that they are investing is in their possession, meaning that they have irrevocable control over those funds.
