Is Brexit an Opportunity to Reform Immigration for Skilled Workers?

In 2010, David Cameron pledged to reduce net migration in the UK to tens of thousands. This was always going to be impossible with the freedom of movement from the European Union. In order to meet their pledge to the electorate, Cameron and Theresa May dutifully reformed the immigration system for non-EU foreigners, notably doing away with the Tier 1 (General) visa for highly skilled workers and the Tier 1 (post-study) visa for those who had earned a higher education degree in the UK. The effect of this immigration reform has been increased complexity and cost for skilled workers coming to the UK. Many of them have just chosen not to come.
