USA, Canada / Looking to move to Poland within the next 5-7 years from the US and need some guidance on your process. [15]

To be clear, my wife and I have semi-joked about moving to Poland for years now. However, the US has progressed very swiftly to a level of comfort with things that we are not really comfortable with. The 5-7 years is solely because I am still active-duty and my wife has to teach a minimum requirement here locally. Your PM's stance on a lot of positions that censor free speech, have honestly solidified us wanting to be apart.

What is the process to become apart of your country and is it very difficult coming from the US?
