I am Polish man who lives in the U.K. for three years. What do I need to emigrate to Australia or Canada?
Is it truth that British Citizen needs visa to emigrate to one of those two contries?
I am a bit confused because Brits, Australian and American citizens speak the same mother language. It is like you would emigrate from Warsaw to Krakow and would need visa to do so.
