A friend of mine relocated to Costa Rica after his wife died.
He loves it there.
Costa Rica could be nice.
Russia would not be my cup of tea at all.
It’s a popular destination for expats. There’s a few countries that allow foreign nationals to have the same rights as citizens..i.e. you can own property and have private property protections, legal rights, atc...Costa Rica is one of those. And they don’t require giving up US Citizenship.
