Thank you for your question
My name is ***** ***** I shall do my best to help you.
The realistic position is that nothing at all will happen in the next 18 months - and the odds are that if we wish to have a trade agreement then like Norway we will have to accept the free movement of people.

Please ask if you need further details
You are most welcome
