You are talking about the EB-5 immigrant visa. The amount of investment is normally $1million, but drops to $500,000 if it is in a targeted employment area.

Generally speaking, the investor comes to the US on a B1 business visitor visa, then finds the investment and then completes the investment. After that, you can file for the EB-5.

You should consult with an immigration attorney.
