Indian and Pacific Ocean

Mauritius is an Indian Ocean island with a tropical climate, excellent beaches, a stable democracy, a good quality of life, a favourable investment environment and low taxes. Mauritius has opened its property market to foreigners by way of controlled property development schemes, including one for retirees. It offers expats the chance to obtain residency and citizenship through an investment of US$500,000 in an approved resort scheme or in a qualifying business activity. Investors can obtain citizenship and passport of Mauritius after approximately five years of residence in the country.
Seychelles is a tropical island group in the Indian Ocean with with pristine beaches, a thriving tourism industry and is a popular destination for retirees and expats. Foreigners who invest in real estate such as villas, houses and apartments automatically qualify for a residence permit in Seychelles conditional on approval from the government. The property must be used only for residential benefit of the buyer and his family and worth a minimum of US$77,000. There are two permanent resident options available for business investors: (1) Invest US$1 million or more in a business physically located in Seychelles and reside in Seychelles for at least one year. A residency permit is valid for five years after which it can be renewed; (2) Invest at least US$1 million and maintain at least five years of business association as a result of the investment - there is no residency requirement then. 

The South Pacific island of Vanuatu has re-launched its CBI programme in March 2017. It is called the Capital Investment Immigration Plan and offers a "honorary citizenship" to foreign investors against one time contribution to a government fund. A single applicant has to contribute $200,000 and a family of four with minor children about $240,000. Potential citizens don't have to live in Vanuatu or even visit the country to qualify. Vanuatu is a member of the Commonwealth and its citizenship provides investors with visa-free travel to 113 countries, including the UK and Schengen states. It also has no capital gains or income taxes. Read more on the Government of Vanuatu's website
