E-1 (Treaty Trader) and E-2 (Treaty Investor) visas are meant for nationals from countries that have commerce and navigation treaties with the United States. The applicant should be entering the U.S. to conduct significant trade, encompassing services or technology, primarily between the U.S. and the treaty-affiliated country (for E-1). Alternatively, for the E-2 visa, the applicant should be aiming to develop and direct the functions of a business where they have made a notable capital investment.
