The single biggest area is time to adapt. It is not knowing exactly what new system they propose to jump into. They are completely crystal clear that free movement is coming to an end. The fear is whether a new system will be ready in time, with the promised reforms, streamlining and improvements. Will that be ready in time?
The vast majority of businesses in this country do not use the non-EU visa system at the moment. It is something in the order of only 30,000 firms in the country that currently use it and that tells me that it is a really quite restrictive, complex and burdensome system. If we are not ready with a new system that is ready to go from day one, without that clarity and without the time to transition into it, that, I think, is probably the biggest concern of all.
