Sorry for the delayed response. Been running around quite a bit lately. Thanks to everyone for replying.
I suppose my pros and cons are as follows:
Pros (i.e. reasons in favor of moving from the US to the UK)- Living in or near Europe (depending on your feelings on this very touchy subject) and among cultures with qualities of life built upon centuries of art, architecture, and cuisine, and where beauty, pleasure, and the company of others are highly valued.
- Living away from a society built upon substantially different pillars, including the constitutional or God-given right to own assault weapons, the 60-hour work week with little to no real vacation, strip mall restaurants and Burger King.
- Raising the kid(s) in a country just a quick flight from other countries where different languages are spoken and different traditions observed
- Raising kid(s) where quality public education and equal access to health care are defended as basic rights.
- The thrill of moving some place new.
Cons (i.e. reasons to stay in the US)- Family is here. It would be great for my parents to be grandparents and to see our kid(s) grow.
- The weather (I'm also in California), the Pacific ocean, and the wild outdoors here.
- I'm an entrepreneur and I know next to nothing about starting businesses in the UK. That said, my businesses running in the US will be fine.
I'm afraid I don't know much about US citizen taxation abroad, but I'd like to know...
