I think there's a distinction between EB-4 Investor Green Card visa and E-2 treaty investor visa. For EB-4, it takes minimum $1 million and pledge to create 10 jobs or $500k in high unemployed region and 10 jobs. For E-2 visa it usually requires $50k to $100k. Of course $200k is a better amount for immigration authority to consider substantial and there is no quota for visa.
