We were told by immigration in Orlando, that we are allowed to stay up to 180 days in a 12 month period. If we overstay, we could be barred from coming back to USA for 10 years, and would have to have an interview at US Embassy in London.
We think 6 months is a good deal for us, we still would have access to health care, if needed, back in UK.
Once upon a time, it was our dream and our wish to move to Florida, but now it is just too difficult, too many hoops etc....
