Only $100k buys you permanent residency in Ukraine. For that you get all the privileges of living in a former Soviet state including BS paperwork that even the IRS would envy. /sarc
Ukraine is on the list of a very few countries that the US still looks on with suspicion. To get your SS check you have to go to the US embassy in person every month.
To further put into perspective how bad it is in Ukraine, there are whole websites of beautiful women who want to leave by marrying men who are 20-70. If they want to leave that badly, I suspect there isn’t much of a future. I know a guy who married a beautiful Ukrainian woman, probably 15 years or more younger than him. They now live in Switzerland.
