It's easy in the sense that it's more or less a sure thing. It's not easy in the sense that you still have to go through a lot of paperwork and bureaucracy, and even have to go in for a doctor to poke you and prod you to see if you're fit to live in the US. Nothing like being treated like livestock to make you feel welcome.

It was way easier for me to deal with the Italian bureaucracy once we were married than it would be for my wife to go to the US. And that's saying something: Italian bureaucracy is about as bad as the stereotypes make it out to be.
