You haven't read the document. This will be a special case of IRL, but not IRL. And it seems to me that, at least on paper, the conditions will be stricter than for the EEA-PR.
The thing is: I cannot trust this government; I cannot trust this Home Office and their predecessors. They are compulsive liars. They'll move the goal post at any occasion. Vote Leave promised an "automatic ILR" for all EU citizens. Where is it? The burden of proof is always on us. I am prepared for the worst. This will be Windrush on steroids, but this time there will be no happy ending.
