Treaty Trader visas and Treaty Investor visas are non-immigrant visas for nationals of a country with which the United States maintains a treaty of friendship, commerce and navigation who wish to go to the United States for one of two purposes: to carry on substantial trade, principally between the United States and the treaty country; or to develop and direct the operations of an enterprise in which the national has invested or is in the process of investing a substantial amount of capital.
