Scotland has called for the old Tier 1 (Post Study Work) visa to be brought back after seeing a notable "brain drain of global talent". 

The Home Office have previously remarked that there would be "no plans" to bring back this visa category as it was said to have "undermined the UK's work migration routes and damage the reputation of our education system". 

One must wonder whether the same arguments will be made in favour of any reforms to the Tier 2 category or the introduction of the Immigration Skills Charge. Many are beginning to argue that the introduction of the Immigration Skills Charge will adversely affect the economy as businesses will not be able to afford to fill the UK skills gap with overseas talent.Will lessons be learned from the closure of Tier 1 (PSW)? The proof will be in the pudding.
