Investors seeking a residency visa for the UK can consider the Tier 1 investment visa. This requires an investment of £2 million and allows temporary residency in the UK for the investor and their immediate family. This residency lasts for 3 years and 4 months and applicants can apply to extend this residency a further 2 years.
Investors can then apply for indefinite leave to remain after 5 years and British citizenship after 6 years. There is no direct UK citizenship by investment program.
