My wife and I (US Citizens), are buying an apartment in a small town in Umbria...we would like to retire and spend at least 6 - 9 months per year in italy, and then 3-6 months with my folks in the USA. Any advice on which Visa to pursue? Just trying to surmise if we should just do the 3 months tourist visa and leave and come back or go for the Permissio Di Sorgiorno? I have read all the posts on residency requirements etc...so have an idea on requirements...
