Yes, at my last birthday a month ago I reached official retirement age and became entitled to Medicare.
Thus, I had to do my due diligence and research both Medicare advantage and Medigap policies in Puerto Rico ( since I am still here) and in the USA and compare them.
I am happy I finally can say something really positive about Puerto Rico: the benefits of the best medicare advantage here are far greater than benefits offered by the best in the USA.
So for retirees on a limited income, especially ones that either require hospitalization or serious dental work, it would be financially beneficial to live in Puerto Rico and enroll in one of the best medicare advantage plans here. They could save thousands of dollars per year... at the cost of dealing with local bureaucracy and with Spanish as a prevalent language, but yes, some things are so far better here ... though these benefits are likely to end once PR becomes a regular state ... if it becomes a regular state.
