Really? Because "freedom of movement" seems to be the sticking point in the Brexit negotiations. The UK can't go the Norway route because it doesn't want "free movement" into its territory.
The UK manages to both have influence over EU immigration policies AND also have exemption to it for non-EU immigration, AND can apply its own limitations even for when immigrants get citizenship for a limited period. Yet many brexiters spout on about how the EU just dictates everything to us and it's all out of our control. Absolute rubbish.
