Its quite common in countries all over Latin America that people who can, will protect themselves in several ways.
Buy at least some property in the US, maybe a condo or something.
Have a bank account in the US.
And when mom is about to give birth, fly her to the US so that the baby is a US citizen. The child may never live as an American, but they’ll keep the blue passport in a safety deposit box for the day that things go badly and they have to go. If you wait until you need a place to go, to start looking for a place to go, you’ve waited too long. And in a politicized economy as most of these are, you need to think ahead. An unlucky change of government can leave you in an untenable position.
That, and a lot of countries are so dangerous for people who have money that they need a place where they can walk the streets without having to worry about kidnappings. You may notice that many Latin entertainers and actors have homes here though they don’t advertise it.
I know people who have had to leave their home country; some arrive and get a lawyer and start working the system. The ones whose parents thought ahead, though, walk through the front door without any problems.
Dear marron, thank you so very much for these valuable insights!
