I would love to do that, I do go to Iceland to visit my family for 3 weeks at a time, but I don't think I could stay for 3 months, because I have children ages 2 and 5 and also I have a home here that I own and lots of pets and stuff, so just up and moving for 3 months just really isn't an option. My older sister (I have 3 sister's) she moved to Iceland when she was pregnant to get the cheaper healthcare for her and her baby a few years ago.
I think I will not be able to get any benefits here in America and that really sucks !!
Of course most of my family lives in Iceland. I love he heat here in America and I need the sunshine for my depression too.

How old are you? I have many cousins and such who live in Reykjavik.
