The precise amount of investment that you have to make when obtaining an E-2 visa is not specified in the US legislation. All it says is that the investment has to be ‘substantial’. Now, how substantial the investment is will depend on many factors including the sector of economy you are putting money in, the geographical location of the intended business, the state authorities’ economic development preferences, and so on. Normally, you have to invest between one and five hundred thousand US dollars into the American economy to qualify for an E-2 visa.
