Caribbean Citizenship‑by‑Investment Programs
| Country | Minimum Investment (single applicant) | Family of 4 | Passport validity | Physical presence |
|---|---|---|---|---|
| Grenada | US $150,000 (donation) | US $200,000 (donation) | 5 years (renewable) | None required |
| St. Kitts & Nevis | US $150,000 (donation) | US $195,000 (donation) | 10 years (renewable) | None required |
| Antigua & Barbuda | US $130,000 (donation) | US $130,000 (family of up to 4) | 5 years (renewable) | 5 days total stay after first 5 years (continuous or split) |
- Common features: No language, interview, or business‑experience tests; no mandatory residence before or after citizenship.
- Alternative routes: Real‑estate investment options exist but are generally less favorable due to higher risk and limited government‑approved projects.
Key considerations when choosing a second passport
- Dual‑nationality policy: Some countries (e.g., Austria) require renunciation, while others (e.g., Ireland, Turkey, Caribbean states) allow dual citizenship.
- Investment type and risk: Direct business investments (Austria, Ireland) may involve operational risk, whereas donation‑based programs (Caribbean) are simpler but lack a tangible asset.
- Residency obligations: Countries like Portugal and Honduras impose minimum physical presence, affecting tax residency and lifestyle.
- Processing time: Ranges from 8 months (Turkey) to several years (Austria, Ireland).
- Travel freedom: Evaluate visa‑free access of each passport relative to personal travel needs.
Prospective applicants should assess financial capacity, willingness to meet residency requirements, and long‑term goals for mobility and security before committing to any program.
