I'd be willing to move to some Canadian big city if someone sponsors me -- Toronto or Vancouver or maybe Montreal.
More seriously, I've considered emigrating, but it would be hard for me to get anywhere unless someone is willing to sponsor me. I'd prefer an Anglophone country: Canada, Australia, New Zealand, the UK, Ireland, and South Africa. Here are other countries:
Non-Anglophone countries with many English speakers and relatively easy languages (I or I+): Denmark, Norway, Sweden, Holland, Belgium, Germany, Austria, Switzerland, Argentina.
Non-Anglophone countries with relatively few English speakers but relatively easy languages (I or I+): France, Spain, Portugal, Italy, Romania, most Latin American countries.
Non-Anglophone countries with many English speakers and relatively difficult languages (II or more): Iceland, Finland, the Baltic states, Poland, Greece, Israel, India, Japan, South Korea, Hong Kong, Taiwan, Nigeria, Kenya, Malaysia, United Arab Emirates, etc.
Non-Anglophone countries with relatively few English speakers and relatively difficult languages (II or more). Lots of them, mostly in Africa, the Middle East, and central Asia, but the biggest are Russia and China.
