Nauru, Vanuatu, and São Tomé and Príncipe are three countries that offer the cost-effective and short timelines to obtain citizenship and a second passport through investment. Vanuatu is the most established of the three, offering a proven program, starting at $130,000. São Tomé and Príncipe offers the lowest entry point, starting at $90,000, and Nauru’s program starts at $115,000, with a key benefit being discretion and minimal publicity.
All three citizenship programs deliver affordability and fast processing speeds, with access to strategic destinations, and the option to include family members. However, the right program depends on your priorities, including whether you prefer to obtain an alternative passport quickly, minimize citizenship costs, access future growth potential, or travel to specific destinations.
This comparison guide breaks down the key differences between São Tomé and Príncipe’s, Nauru’s, and Vanuatu’s citizenship programs, the total citizenship cost, eligible dependents, citizenship timelines, and pros and cons.

Vanuatu Citizenship by Investment was introduced in 2017 to generate revenue for economic development, national debt reduction, and to finance post-disaster relief efforts. It was the first citizenship program to be launched in Oceania and later became a viable alternative in a Caribbean citizenship by investment comparison.
Investors can obtain approval for citizenship and a Vanuatu passport within two to four months through a non-refundable or partially refundable contribution or a real estate investment. The minimum investment threshold is $130,000, and applicants can include their spouses, children, parents, and grandparents. An Authorized Agent or Vanuatu citizenship lawyer must be used to apply.
Eligible dependents
- Spouse
- Children under 18
- Children under 25 and in full-time education
- Parents and grandparents over 50
Cost
The minimum investment amount depends on the investment: The Development Support Program (DSP) requires a $130,000; the Capital Investment Immigration Plan (CIIP) requires a $165,000 donation (with $50,000 redeemable after five years) and Vanuatu real estate requires a property investment valued at least $200,000. The CIIP and real estate minimum thresholds apply to a single applicant or family of up to four.
Additional investment is needed to include dependents when donating to the DSP. While the CIIP has a higher upfront cost, its partial refund brings the investment down to $115,000 for up to four applicants.
A nominal application fee of $40 applies per applicant ($250 for the CIIP option). The due diligence fee is $5,000 for a single applicant and applications including family members. The combined citizenship certificate and passport fee is $280 per applicant.

Single applicant
Nauru’s limited time discount of $25,000 reduces the total citizenship cost for single applicants to $102,700.
Family of four

This reduces the total investment requirement to $122,620 for a family of four. Nauru’s limited-time discount of $25,000 reduces the total citizenship cost for families with a child over 16 and one under 16 to $120,700.
