Passport comparison
Compare programmes without pretending they are the same.
St. Kitts & Nevis citizenship is not a Portuguese residence permit, a UAE visa, or a US green card. The tool is built to keep those distinctions visible.
St. Kitts & Nevis, beside the names clients actually mention
Each programme is shown as the document it actually produces: a passport, a residence permit, a visa or a green card. Scores are informational only.

| Process | Application through an Authorised Agent; due diligence; interview; Approval in Principle; then qualifying investment and citizenship. The Unit has described a 120–180 day indication window from acknowledgment. | Residence permit, renewals, and a separate naturalisation analysis after meeting legal residence criteria. | Authorised/licensed agent, due diligence and government processing. |
| Residency | No mandatory residency period is described as a condition of the investment route. | Residence routes involve stay, tax and compliance conditions. Citizenship, if pursued, is a later legal step. | Confirm whether any visit or residency condition currently applies. |
| Capital and family | |||
| Investment | From US$250,000 under published contribution routes; from US$325,000 for approved developer real estate. Confirm current minima. | Portugal’s residence-by-investment options have been revised. Current qualifying investments and funds should be confirmed; this is not citizenship on approval. | Contribution and real-estate routes exist. Confirm current published thresholds. |
| Real estate | Approved developer real estate and approved private real estate routes are available. | Real-estate qualification has been restricted in recent reforms. Do not assume property still qualifies. | Approved real-estate projects form part of the usual menu. |
| Family | Eligible dependants may be included subject to current programme definitions. Do not assume eligibility. | Family reunification may be available under residence rules. | Family members may be included where they meet programme definitions. |
| Diligence and aftermath | |||
| Due diligence | Independent background screening, source-of-funds review, interview for the main applicant, and possible interview for dependants aged 16+. | Immigration, AML and source-of-funds checks apply. | Background checks and source-of-funds review apply. |
| Travel access | A St. Kitts and Nevis passport may support international travel subject to destination rules. Access lists change. Verify before travel. | A Portuguese residence permit supports Schengen travel subject to permit conditions. It is not a passport. | Grenada is frequently discussed for particular bilateral arrangements. Treat any access claim as subject to change and verify officially. |
| Tax | Citizenship does not automatically create or remove tax residence. Personal tax position depends on facts, ties and professional advice. | Portuguese tax residence can arise from days and ties. Professional advice is essential. | Independent tax advice is required; do not assume treaty outcomes. |

Document covers are stylised and conceptual. They are not reproductions of official passport designs, chips, or security features. A residence permit, visa or green card is shown as a different object because it is a different legal product.
Private consultation
A comparison is not a recommendation.
If the objective is second nationality without a European residence project, the Caribbean CBI category is the relevant one. We can then talk about St. Kitts specifically.
