I’ve been sorta thinking of Panama as a possibility. Alternatively, parts of Europe might also work. I’m a third generation American which means there are a couple of countries that might allow me dual citizenship.
I’ve lived in Canada and it’s beautiful there, but if you are someplace urban it’s outrageously expensive. The rural areas aren’t too bad though and the exchange rate is generally in your favor if your money is coming from the US. I have landed immigrancy status there because I was married to a Canadian.
