Having a second passport allows you to strategically plan your future, to guarantee financial freedom, to create a secure future for your family, and to enhance global mobility.
This article deeply examines available citizenship investment programs in Oceania and the Caribbean. We will delve into comparing minimum investment amounts, involved due diligence costs, and other perks to find out the cheapest economic citizenship program.
Top 5 Criteria to find Cheapest Citizenship by Investment Program

Available Investment Options
Most economic citizenship programs offer more than one route to get citizenship.
For instance, Saint Lucia’s CBI program allows investors to invest in government bonds. The CBI program of St. Kitts offers financing of public benefit projects throughout the island. Other countries, like Grenada or Nauru, accept donations to national development funds aimed at financing public infrastructure.
The selection of a particular investment option is closely connected with your future goals. If you plan to live in a country after getting citizenship, the real estate investment sounds like a good plan. If, however, the aim of getting a second passport is the access to global mobility, in that case the donation option might be the best way to do things.
Number of Applicants
The sum of a final investment significantly depends on the composition of a family. The same CBI program can be the cheapest for a single applicant and the most expensive for a big family.
In some Caribbean citizenship programs, you need to pay an additional fee for adding certain family members into the application. For instance, in Grenada an investor needs to pay an extra USD 75,000 in order to include their siblings in the application.
On the other hand, in Antigua and Barbuda, the CBI program welcomes only families having at least six members in order to be eligible for the investment into the education project.
Taxes Involved
Holding a passport of another country imposes a duty of paying taxes.
If you plan to make a real estate investment, first, make sure there is no capital gains tax. Otherwise you may end up paying a portion of the property’s value as a tax. The good news is that there is no wealth or inheritance tax in either Caribbean or Oceania CBI countries.
If you apply for citizenship in order to be able to live in a country at some point, think in advance about personal income tax. In countries like St. Lucia, tax residents should pay taxes on income generated inside and outside of St. Lucia.

Additional Costs
In order to find out the cheapest citizenship by investment program, you need to calculate additional due diligence and application fees.
Besides that, when it comes to real estate investment, most Caribbean CBI programs apply additional government fees in case of approval in principle. Those fees vary between USD 25,000 and USD 100,000 depending on the composition of the applicant’s family.
Benefits and Perks
There is no perfect CBI program. Everything depends on the goal you would like to pursue once the citizenship is granted.
If you are looking for visa-free travel, pick up investment programs with the highest global mobility (e.g., Saint Kitts).
If you are looking for something very cheap and want to preserve trips to the UK at the same time, in that case the Nauru Citizenship by Investment Program could be a good choice.
The Caribbean Citizenship: Advantages and Costs
The Caribbean offers a wide selection of CBI programs to choose from. Each citizenship program has unique and remarkable features.
All Caribbean programs share certain advantages:
- First, getting a passport in one CBI program gives you a right to become a part of a residency program in another Caribbean country, which is a part of CARICOM.
- Second, all Caribbean countries offer visa-free access to the European Union. Unlike European Golden Visa programs offering temporary rights to reside and travel within the EU, the Caribbean passport can permanently secure your Schengen trips.
However, when it comes to traveling globally, visa advantages of Caribbean passports may differ significantly. For instance, St. Lucia could offer visa-free trips to China, while Antigua has visa-free travel with South Africa.
The same differences could be found when it comes to eligibility requirements for family members or the selection of available investment options.
