LONDON (Web Desk) — Several countries around the world continue to offer citizenship-by-investment (CBI) programmes in 2026, providing eligible foreign investors with a legal pathway to acquire a second passport in exchange for qualifying investments or contributions.
Often referred to as “golden passport” programmes, these initiatives are primarily operated by smaller island nations seeking to attract foreign investment to strengthen public finances, fund infrastructure projects, boost tourism and diversify their economies. While the programmes differ from one country to another, applicants are generally required to undergo extensive background checks, satisfy anti-money laundering regulations and prove the lawful source of their funds before citizenship is approved.
Unlike residency-by-investment programmes—which usually require several years of residence before citizenship can be obtained—many CBI programmes grant citizenship within a few months after successful completion of the application process.
Here are eight countries offering some of the most affordable citizenship-by-investment programmes in 2026.
1. St. Kitts and Nevis
Minimum investment: US$250,000

St. Kitts and Nevis operates the world’s oldest citizenship-by-investment programme, established in 1984. Its decades-long experience has made it one of the most recognised CBI programmes globally.
Applicants can qualify by making a non-refundable contribution of at least US$250,000 to a government-approved public benefit fund. Another option is purchasing government-approved real estate worth at least US$325,000, which must generally be retained for a minimum holding period before resale.
Applications are typically processed in around four months, although processing times may vary depending on due diligence reviews and documentation.
The twin-island Caribbean nation has a population of about 50,000 people and relies heavily on tourism and international financial services.
2. Saint Lucia
Minimum investment: US$240,000
Saint Lucia introduced its citizenship-by-investment programme in 2015 and has since become one of the Caribbean’s most competitive options.
Applicants may qualify through a government contribution starting at US$240,000 or by investing at least US$300,000 in approved real estate developments.
The country also offers other qualifying investment routes under certain conditions, although government contributions remain the most popular option.
Processing generally takes around six months, and applicants should expect additional government, due diligence and administrative fees beyond the minimum investment.
Saint Lucia has a population of approximately 185,000 and is known for its tourism-driven economy, volcanic landscapes and tropical climate.
3. Grenada
Minimum investment: US$235,000
Grenada offers another attractive Caribbean citizenship programme, with applicants eligible through a government contribution or an approved real estate investment.
The minimum property investment generally starts at US$270,000, making it one of the region’s more affordable real estate options.
Grenada is particularly attractive because its passport provides visa-free or visa-on-arrival access to numerous countries and offers additional international mobility benefits compared with some competing programmes.
The island nation has a population of nearly 120,000 people and is known worldwide as the “Spice Isle” due to its production of nutmeg and other spices.
4. Antigua and Barbuda
Minimum investment: US$230,000
Antigua and Barbuda continues to attract investors through its well-established citizenship programme.
Applicants may qualify by making a qualifying government contribution or investing at least US$300,000 in government-approved real estate projects.
The application process usually takes around six months following successful completion of background checks and submission of all required documentation.
Located in the eastern Caribbean, Antigua and Barbuda has a population of just under 100,000 and depends significantly on tourism and offshore financial services.
5. Dominica
Minimum investment: US$200,000
Dominica remains one of the Caribbean’s most affordable citizenship-by-investment destinations.
Applicants may either contribute US$200,000 to a government-approved fund or purchase approved real estate of equal value.
While the property investment route offers the possibility of recovering part of the investment through resale after the required holding period, it generally involves additional legal, government and processing fees and often takes longer to complete than the donation option.
Dominica has a population of approximately 70,000 people and is internationally recognised for its rainforests, waterfalls and eco-tourism industry.
6. Vanuatu
Minimum investment: US$130,000
Located in the South Pacific, Vanuatu offers one of the world’s fastest citizenship-by-investment programmes.
Successful applicants often receive approval within one to two months, making it one of the quickest legal routes to obtaining a second passport.
Applicants must complete extensive due diligence procedures before approval, and citizenship is granted only after all legal requirements have been satisfied.
Vanuatu consists of more than 80 islands and has a population of around 340,000 people.
7. Nauru
Minimum investment: US$90,000–105,000
Nauru is among the world’s smallest independent nations and offers one of the least expensive citizenship programmes currently available.
The final investment amount varies depending on the applicant’s circumstances, family composition and government fees.
Covering just eight square miles, Nauru has a population of roughly 12,000 people, making it one of the world’s least populated sovereign states.
Its remote Pacific location appeals to applicants seeking an alternative citizenship from a politically stable island nation.
8. São Tomé and Príncipe
Minimum investment: Approximately US$90,000
São Tomé and Príncipe offers one of the lowest-cost citizenship opportunities available.
Situated in the Gulf of Guinea off the west coast of Central Africa, the island nation combines tropical scenery with year-round warm weather.
Portuguese is the country’s official language, reflecting its colonial history, while the population of approximately 230,000 relies mainly on agriculture, fishing and tourism.
The islands are increasingly attracting international attention for eco-tourism and sustainable development opportunities.
Why countries offer citizenship by investment
Citizenship-by-investment programmes are designed to attract foreign capital that can be used to support national development.
Funds generated through these programmes often finance public infrastructure, healthcare, education, disaster recovery, tourism development and other government priorities. For many small island states with limited natural resources, CBI programmes have become an important source of national revenue.
Benefits for investors
Investors seek second citizenship for a variety of reasons, including greater international mobility, easier global business operations, wealth diversification, family security and access to alternative places to live, work or retire.
Depending on the country, passport holders may enjoy visa-free or visa-on-arrival travel to numerous destinations, although travel privileges differ significantly between programmes.
Important considerations before applying
Experts advise applicants to conduct thorough research before making any investment.
Prospective investors should compare:
- Total government and processing fees
- Due diligence requirements
- Processing times
- Visa-free travel benefits
- Family eligibility rules
- Tax obligations
- Property holding requirements
- Investment recovery options
- Programme reputation and long-term stability
Applicants should also work with licensed immigration professionals and verify all information through official government sources, as citizenship-by-investment programmes are periodically updated. Several countries have revised investment thresholds, eligibility rules and due diligence standards in recent years in response to international regulatory requirements.
While these programmes provide a legal route to acquiring a second citizenship, approval is never guaranteed. Governments retain the authority to reject applications that fail security, financial or due diligence assessments.
