EB-5 is the only US program that converts investment directly into permanent residency: US$800,000 into a targeted employment area project (US$1,050,000 elsewhere) that creates at least ten full-time American jobs, with green cards for you, your spouse, and unmarried children under 21. E-2 is faster and lighter on capital but is a renewable non-immigrant status rather than residency, and it is open only to nationals of treaty countries — including Canada and Grenada, which is why Grenadian citizenship is often paired with it.
