It's not necessary to be in the EU to study, live & work in each other's countries
Leaving the EU will simply mean that we have the power to end *automatic* freedom-of-movement. It doesn't mean that we won't be allowed to have anything to do with our neighbours.

All the EU citizens who want to live and work in the UK who have the right qualifications will be given permits to do so. Similarly, for British citizens on the Continent.

The people who will be refused permits are criminals, and people who do not have the skills we require.

I take it that your CERN colleagues aren't exclusively made up of people from EU countries? I'm sure there must be the odd Canadian, or Indian citizen working there? How do you think that they are able to do so? With permission, of course.

Yeah that'd be really convenient, but it's not the reality. The reality is, you won't have a clue what the reality is until you've negotiated your exit from the EU.
