As of the 17th February 2022, the UK Government official website has stated that it is no longer possible to apply for a new Tier 1 (Investor) visa. The closure of this route affects all new applicants from all nationalities with immediate effect. This means that if an applicant was preparing to submit his Investor visa petition to the Home Office, the route is no longer valid. The Investor visa route has been discussed publicly for over a few years, and many articles can be found discussing the advantages and the disadvantages of the route. The Home Office has provided “Security concerns” as the reason for the immediate closure of the scheme.
If someone already applied and paid for the visa or was already granted this visa (or had one in the last 12 months, and it was their most recent visa), they can still apply to extend their visa for 2 years, for family members to join them and to settle in the UK (indefinite leave to remain). Applications for leave to remain from existing Investor visa holders must be made before 17 February 2026. Applications for indefinite leave must be made before 17 February 2028. (GOV.UK)
