An Investor Visa is sometimes referred to as a Treaty Visa. This is because the United States of America maintains treaties of commerce and navigation with certain countries. The Immigration and Naturalisation Act gives non-immigrant visa status to an individual whose country maintains this treaty with the Untied States. The Investor Visa is given to the individual who is coming into the United States to conduct substantial trade, including business in technology or services mainly between the US and the country with the treaty. The business should direct and develop operations of enterprise that the individual has or is considering investing large amounts of capital.

The requirements of the Investor Visa or the Treaty Visa include the point that the investor is a corporate or real person and that the investor is of the nationality of the treaty country. The investment to be made in the United States should be substantial in magnitude. Within the same bracket, the portion of the investment being made for a low-cast stature of business enterprise should be more than the portion of investment being made for a high-cost business.

The Investor Visa applicant must show proof that the investment is a real and operating enterprise that is not idle or speculative.  Uncommitted money and funds held in an account in the bank or like securities are not deemed as investments. Further, the investment must not generate marginal profits but should reap significantly more profit than merely to provide the investor and his/her family a living. It, therefore, must provide a notable positive economic impact for the US.
