I'm an American citizen, my wife has dual citizenship (Poland and U.S.) and we are planning and moving/retiring to Krakow within the next year or so. She has property in Krakow in which we'll live. We are also thinking of having a home built just outside of the city. Can anyone please let us know what hurdles we might face? Will I be able to use the state medical resources or will I (or both of us) need extra insurance? How does the taxation work on income from the US (rental property income, Social Security, Stocks, etc.)? Will I need to become a Polish citizen and. if so, how does that process work? Any insight would be greatly appreciated. Thanks
