They would be able to keep their french health insurance, it helps!
I said they are not rich enough for EB5 (which requires $850.000 and is a risky investment), it doesn"t mean they are poor! In fact, they own multiple condos for rental income, and 1 for family use (we've spent our vacations there for the past 20 years). My father is retired, but my mother is still working, remotely, they have assets in the US, they would have enough money to support themselves, and they certainly don't want to be a public charge.
The point of my first post was just to know if there may be a way around the "2 years of work experience in the past 5 years" requirement for a retiree!
