You can go to Ireland, via the CTA. Live here five years, fill out a very long form, wait an indeterminate time for the form to be processed, and you have an EU citizenship again!(You can keep the UK one, too; dual Irish/UK citizenships are permissible and common).
Also, check for any Irish or Italian grandparents; you may already have won an exciting new citizenship!
One of you lot recently married an American and moved to Canada. Queen's a bit salty, but they seem to be doing well for themselves. But seriously, I'm an American living in Canada, planning on getting citizenship here. The British immigrants I've met seem to get along pretty well here.
Nah, they're back in Santa Barbara, California. Vancouver Island is a beautiful area, but it's pretty far from the nexus of the entertainment industry.
The UK and Canada are quite culturally similar though. I could see CANZUK working pretty well, if the politicians ever get around to implementing it.
Seconding Ireland. Also, out of habit I recommend The Netherlands + Scandinavia. Wealthy, competently run places. New Zealand is great, but 30 hours of travel to visit family is not super great.
What countries would you go to as an English expat for a better life? Where can you change a useless English citizenship for another?
