@geauxlsu32, if you or both you and your wife are going to be retired then I guess the language won't be such an issue as in case when you would have to find a job here, but it's still an issue... Polish is a difficult language, I'd slowly start learning it already if I were you...
Btw, why Poland? Do you or your wife have Polish roots?
As for politics, in 5-7 years time we may have a different government, so I'm not sure if that's a good enough reason to move across the ocean...
Do you know already where exactly in Poland you would like to live?
What is the process to become apart from your country
What do you mean by that?
