There is a good chance that after Brex*it you may not have rights to live in Portugal though..
You are correct but there is bound to be immigration opportunity just as in Australia & America. It's such a sh*tstorm politically currently that the outcome is completely unpredictable in my eyes. I may also try and register before brexit which is an option.
