Is it easier for a UK citizen to emigrate to USA or Canada?
Ah, Canada is not the UK as you undoubtably know. United Kingdom and Commonwealth are slippery concepts. You will need the same sorts of things for both and both will do background checks – like see if you have police record. Canada for sure will require a health exam from an approved doctor. For Canada it’s pretty easy to add up your points of desireability as an immigrant and see what your chances are. Unless you have a job waiting for you or a lot of money you can expect a 2 year wait for Canada immigration.
