Our view is that a full closure of the visa category would be like using a sledgehammer to crack a nut. Perfectly sensible due diligence requirements have been in place since 2015 and these could potentially be enhanced further.
If the visa category is closed it is not clear yet what transitional provisions will be put in place or how the Home Office will treat those already granted Tier 1 (Investor) visas. It is a corner stone of public law that new rules should not be applied retrospectively to visas already granted and we are ready to seek judicial remedy if required.
Please contact our Citizenship and Immigration team if you have any questions in relation to this.
