many countries offer the Investment Visa option. Canada does, as do places like NZ:
> New Zealand offers the Active Investor Plus Visa, which requires a minimum investment of NZD $5 million for the Growth category or NZD $10 million for the Balanced category. This visa allows investors to live, work, and study in New Zealand, with pathways to permanent residency after maintaining the investment for the required period.
After 5 years of investment, the visa holders can apply for Permanent Resident status, and after 5 years of PR, citizenship.
