If I was American I would probably consider Goonerland or Australia and Canada if you don´t mind the weather. The UK will give you a culture shock when you realise that the purchasing power is an absolute outrage and the cost of living as such is rediculously high.
Another destination would be Ireland. You would be a resident of Euroland which facilitates doing business and travel with other European countries – if you don´t mind grey skies and rain that is.
