# Which citizenship by investment programmes have the lowest qualifying amounts?

The lowest published contribution floors in this inventory are US$90,000 in Nauru and São Tomé and Príncipe. Nauru’s amount is a temporary offer. Their government and professional charges differ, so equal headline amounts do not mean equal total costs.

| Programme | Single base | Family base | Single subtotal |
| --- | --- | --- | --- |
| [🇳🇷Nauru](https://cbi.me/citizenship-by-investment/nauru/) | $90,000 | $92,000 | $102,700 |
| [🇸🇹São Tomé and Príncipe](https://cbi.me/citizenship-by-investment/sao-tome-and-principe/) | $90,000 | $95,000 | — |
| [🇻🇺Vanuatu](https://cbi.me/citizenship-by-investment/vanuatu/) | $130,000 | $180,000 | $135,000 |
| [🇩🇲Dominica](https://cbi.me/citizenship-by-investment/dominica/) | $200,000 | $250,000 | $210,000 |
| [🇦🇬Antigua and Barbuda](https://cbi.me/citizenship-by-investment/antigua-and-barbuda/) | $230,000 | $230,000 | $248,800 |

Family: principal, spouse and two under-12 children. Subtotals include itemised charges only; extras and eligibility apply.

## Compare fees as well as the contribution

Nauru’s enumerated single-applicant charges produce a US$102,700 subtotal before professional/document extras. Do not treat US$90,000 as either programme’s guaranteed all-in price.

## Compare the family you actually have

The under-12 family illustration has a US$92,000 contribution in Nauru and US$95,000 in São Tomé. Adult dependant completion is currently paused for affected São Tomé relatives. Family eligibility matters alongside price.

## Check the deadline and the outcome

Nauru’s offer applies to qualifying applications filed before 31 December 2026. Investor residency, an announced programme and a discretionary citizenship provision should not be ranked as purchasable citizenship offers.
