Cambodia's Citizenship by Investment program stands utterly alone in the global investment migration landscape. While every other major CBI program maintains extensive lists of restricted nationalities—from Russia and Iran to North Korea and Afghanistan—Cambodia accepts applications from citizens of any country on Earth. This remarkable openness, rooted in constitutional neutrality and non-alignment principles, creates both extraordinary opportunities and significant risks in an industry facing unprecedented international scrutiny.

The absence of nationality restrictions in Cambodia's CBI program isn't an oversight or administrative gap—it's a deliberate policy choice reflecting the Kingdom's foreign policy philosophy. As the only CBI program without banned nationalities, Cambodia offers a unique pathway to citizenship for investors from countries typically excluded elsewhere, though significant operational challenges and recent constitutional changes complicate this theoretical advantage.

The landscape of global nationality restrictions

Understanding Cambodia's unique position requires examining the standard practice across the investment migration industry. Among active CBI programs worldwide, nationality restrictions have become the norm rather than the exception. Caribbean nations, which dominate the CBI market with programs generating billions in annual revenue, maintain comprehensive banned lists. Saint Kitts and Nevis restricts six nationalities including Russia, Belarus, and Iran. Antigua and Barbuda bans eight countries outright, though it permits conditional eligibility for banned nationals who've maintained decade-long residence in approved countries like Canada or the United States.

The European approach proves even more restrictive. Malta's MEIN program, before recent court challenges, maintained the industry's most extensive ban list with twelve restricted nationalities including Afghanistan, Syria, and Venezuela. The now-discontinued Cyprus program, while operational, focused on general due diligence rather than nationality-based exclusions—an approach that ultimately contributed to its downfall amid corruption scandals.

These restrictions stem from multiple factors: compliance with international sanctions, security concerns about terrorism financing, diplomatic pressures from key allies, and reputational risk management. Programs use nationality bans as a crude but effective first-line defense against potentially problematic applicants, signaling to international partners their commitment to program integrity.

Cambodia's constitutional neutrality drives open access

Cambodia's decision to maintain no nationality restrictions flows directly from constitutional principles and foreign policy traditions that distinguish it from other CBI jurisdictions. Article 53 of Cambodia's 1993 Constitution mandates "permanent neutrality" and "non-alignment" as foundational principles of the state. This commitment to neutrality isn't mere rhetoric—it shapes Cambodia's entire approach to international relations and, by extension, its citizenship policies.

The Ministry of Foreign Affairs articulates this philosophy clearly: "Cambodia will continue to uphold its independent decision making in both domestic and foreign policy aspects with respect to the principles of permanent neutrality, non-alignment, peaceful coexistence with neighbors and with all countries in the world." This stance means Cambodia maintains diplomatic relations with countries others shun, including long-standing ties with North Korea dating to 1965 and full diplomatic engagement with Russia despite current global tensions.

Cambodia's adherence to ASEAN's core principles of non-interference and non-aggression reinforces this approach. Within the Southeast Asian context, Cambodia practices what scholars term a "hedging strategy," balancing relationships with major powers while avoiding alignments that could compromise sovereignty or limit economic opportunities. Prime Minister Hun Manet has emphasized Cambodia's commitment to "win-win partnerships across all sectors," reflecting an economic diplomacy that prioritizes development over geopolitical positioning.

This neutrality translates directly into CBI policy. Where other programs use nationality restrictions to signal alignment with Western security concerns or comply with partner country demands, Cambodia's constitutional commitment to universal diplomatic engagement precludes such discrimination. The absence of banned nationalities isn't a gap in program design—it's a feature reflecting deeper principles of Cambodian statecraft.

Current program structure and requirements

Cambodia's CBI program operates through three primary investment routes established under the 1996 Law on Nationality, specifically Articles 10, 11, and 12. The first option involves a direct donation of $245,000 (1 billion KHR) to the national budget for economic development. The second and third options require $305,000 (1.25 billion KHR) investments either through projects approved by the Cambodia Development Council or with direct Royal Government authorization.

Beyond these base investments, applicants face additional fees totaling approximately $85,000, structured as an initial deposit of $5,000, pre-submission payment of $25,000, post-approval fee of $40,000, and passport collection charge of $15,000. Processing typically requires three to six months, though significant variability exists depending on connections and circumstances.

The program's benefits center primarily on land ownership rights—a privilege reserved exclusively for Cambodian citizens. While the passport provides only 53 visa-free destinations compared to 140-160 for Caribbean programs, the ability to purchase and develop real estate drives most investor interest. Cambodia permits dual citizenship, allowing investors to maintain their original nationalities, and provides access to ASEAN Economic Community benefits including enhanced regional mobility.

Applicants must fulfill several requirements beyond investment. These include passing a Khmer literature exam covering Cambodian history, language, and culture administered by the Ministry of Interior. Physical presence in Cambodia is mandatory for completing the final investment, taking the oath of allegiance, and collecting citizenship documents. Investment route applicants must also register a place of residence within Cambodia.

The reality behind open eligibility

While Cambodia's lack of nationality restrictions appears remarkably inclusive, practical barriers create a different reality. Multiple sources confirm that obtaining Cambodian citizenship "requires connections with the King of Cambodia," transforming what seems like an open program into one of the world's most exclusive. The King holds discretionary authority to grant citizenship, and no established official procedure exists for navigating this requirement.

This opacity extends throughout the program. Cambodia scores zero percent on investment migration transparency indices, having never reported application volumes, approval rates, or revenue figures. Unlike Caribbean programs that publish quarterly statistics and maintain dedicated CBI units, Cambodia's program operates through informal channels with significant fee variability. Service providers report costs ranging from $40,000 to $60,000 with inconsistent requirements between applicants.

The absence of implementing sub-decrees for CBI procedures, despite the 1996 law mandating such regulations, creates legal ambiguity. This regulatory vacuum means each application becomes a unique negotiation rather than a standardized process, favoring those with existing government relationships while excluding typical international investors accustomed to transparent procedures.

Constitutional changes reshape citizenship landscape

July 2025 brought seismic changes to Cambodia's citizenship framework through constitutional amendments that fundamentally alter the security of acquired nationality. The previous Article 33 guaranteed that "No Khmer citizen shall be deprived of their nationality, exiled, or extradited to another country except through mutual agreement." The amended version states simply: "Receiving, losing, and revoking Khmer nationality shall be determined by law."

This change, proposed by Senate President Hun Sen and unanimously approved by the National Assembly, grants the government unprecedented power to revoke citizenship from any Cambodian, including those who acquired nationality through investment. Justice Minister Koeut Rith justified the amendment as necessary to "purify patriotism and loyalty" and target those who "collude with foreign powers against the state."

The implications for CBI participants are profound. Where previously naturalized citizens enjoyed constitutional protection against arbitrary denationalization, they now face potential revocation based on criteria yet to be defined in pending legislation. This retroactive vulnerability transforms Cambodia's CBI from a permanent acquisition into a conditional status subject to political considerations.

International human rights organizations condemned the amendment as a "heinous violation of international law," warning it could render individuals stateless in violation of fundamental human rights principles. For CBI investors, particularly those who renounced original citizenships to comply with Cambodia's requirements, the amendment introduces existential risks to their legal status and security.

Comparative analysis reveals competitive challenges

Cambodia's position as the sole CBI program without nationality restrictions creates interesting market dynamics. Theoretically, this openness should attract investors from the approximately 15-20 nationalities commonly banned elsewhere—a substantial market including wealthy individuals from Russia, Iran, and other restricted countries. However, operational realities complicate this advantage.

The program's opacity and informal requirements deter mainstream investors accustomed to transparent processes. While a Russian billionaire might face automatic rejection in Saint Kitts or Malta, navigating Cambodia's requirement for royal connections may prove equally challenging without pre-existing relationships. The weak passport offering just 53 visa-free destinations compared to 140-160 for Caribbean alternatives further limits appeal for mobility-focused investors.

Revenue generation data starkly illustrates these challenges. While Dominica's CBI program generates revenue equivalent to 37% of GDP and Grenada reported $186 million in the first half of 2024 alone, Cambodia provides no statistics on program performance. Historical references suggest approximately 1,036 citizenships granted by investment as of 2018, minimal compared to Caribbean programs processing hundreds of applications quarterly.

Cambodia's inclusion in the U.S. State Department's June 2025 draft travel ban memorandum specifically citing "availability of citizenship by monetary investment without residency requirement" represents another competitive disadvantage. This potential restriction would eliminate U.S. travel privileges for Cambodian passport holders, devastating the program's already limited mobility benefits.

The legal architecture of Cambodia's CBI program reveals both the source of its nationality openness and its operational challenges. The foundational 1996 Law on Nationality establishes investment pathways without mentioning nationality restrictions, creating the legal basis for universal eligibility. However, Article 16's mandate that naturalization procedures "shall be determined by Sub-decree" remains unfulfilled nearly three decades later.

This missing implementing framework creates a legal vacuum filled by informal practices and discretionary decisions. Where other programs publish detailed regulations covering due diligence procedures, application processes, and specific requirements, Cambodia operates through undocumented channels. This absence of formal procedures enables the flexibility to accept any nationality but also permits the arbitrary treatment and corruption risks that damage program credibility.

The recent constitutional amendments compound these challenges by introducing new legal uncertainties. The pending citizenship revocation law, which Justice Minister Koeut Rith promises will be "swiftly brought before parliament," will establish criteria and procedures for denationalization. For CBI participants, this creates a moving target where the terms of their citizenship investment may change retroactively based on political considerations.

International legal scholars note potential conflicts with Cambodia's obligations under international law, particularly regarding statelessness prevention. The 1961 Convention on Reduction of Statelessness, while not ratified by Cambodia, reflects customary international law principles against arbitrary denationalization. CBI investors who surrendered original nationalities may find themselves in legally precarious positions if Cambodia exercises new revocation powers.

Security concerns and due diligence implications

The absence of nationality-based restrictions doesn't mean Cambodia ignores security considerations entirely. The country implements UN Security Council sanctions through its Law on Anti-Money Laundering and Combating Terrorist Financing, maintaining court-ordered freezing mechanisms for designated individuals and entities. However, these measures target specific persons rather than entire nationalities, preserving the program's universal eligibility.

Due diligence challenges multiply when accepting applicants from any country. Jurisdictions with limited governmental cooperation, poor record-keeping, or ongoing conflicts make background verification difficult or impossible. While Caribbean programs address this through blanket nationality bans, Cambodia must theoretically conduct enhanced due diligence on a case-by-case basis for high-risk applicants.

The practical reality likely involves limited systematic screening given the program's informal nature and lack of dedicated processing infrastructure. Without a specialized CBI unit or standardized procedures, consistent security vetting across diverse nationalities seems improbable. This gap between theoretical universal access and practical security requirements represents a fundamental program weakness.

Financial Action Task Force recommendations emphasize risk-based approaches to customer due diligence, with enhanced measures for higher-risk situations. Cambodia's approach—accepting any nationality while lacking transparent procedures—appears to violate these principles, potentially exposing the country to money laundering and terrorism financing risks that justify other programs' nationality restrictions.

Economic impact and development considerations

Unlike Caribbean nations where CBI revenues constitute 20-37% of GDP, Cambodia's program appears to generate minimal economic impact relative to the nation's $28.54 billion economy. The lack of published statistics prevents precise analysis, but the absence of reported revenues in national budgets or development plans suggests limited contribution compared to traditional foreign direct investment channels.

This minimal economic reliance shapes Cambodia's approach to program design and international pressure. Where Caribbean nations carefully balance inclusivity with international acceptance to protect vital revenue streams, Cambodia can maintain principled positions on neutrality without jeopardizing critical income. The program serves more as a niche offering for specific investors seeking land ownership than a cornerstone of economic policy.

The primary economic benefit flows through real estate development enabled by citizenship acquisition. Foreign investors seeking to develop hotels, casinos, or commercial properties find citizenship valuable for avoiding complex ownership structures required of non-citizens. This targeted benefit explains the program's continuation despite limited broader economic impact and international criticism.

However, opportunity costs merit consideration. Cambodia's corruption ranking of 158/180 on Transparency International's index and inclusion in various international watchlists complicate broader investment attraction efforts. A transparent, well-regulated CBI program could enhance the country's reputation and generate meaningful revenues, but current operations may reinforce negative perceptions that deter mainstream investors.

Future outlook and strategic implications

The Cambodia CBI program faces an uncertain future shaped by competing pressures. International scrutiny, particularly from the United States, threatens the program's viability in current form. The 60-day review period established in the State Department memorandum requires countries to address identified deficiencies or face travel restrictions that would devastate program appeal.

Three scenarios appear most likely. First, Cambodia could implement significant reforms including enhanced transparency, possible residency requirements, and even nationality restrictions to align with international standards. This pathway, with approximately 30% probability, would preserve the program while sacrificing its unique universal eligibility.

Second, international pressure could force program suspension, following precedents in Moldova and Montenegro. This scenario, with roughly 50% probability, would end Cambodia's CBI offering entirely rather than compromise neutrality principles. Existing citizens would likely retain status, but new applications would cease.

Third, Cambodia might maintain current operations while accepting consequences like U.S. travel restrictions. This status quo approach, with about 20% probability, would further marginalize the program but preserve principled positions on neutrality and non-discrimination.

For prospective investors, these uncertainties counsel extreme caution. The combination of operational opacity, constitutional vulnerability through new revocation powers, and international pressure creates multiple risk vectors. Investors from banned nationalities seeking alternatives should carefully weigh Cambodia's theoretical openness against practical challenges and future uncertainties.

Strategic recommendations and conclusions

Cambodia's CBI program represents a fascinating case study in how constitutional principles and foreign policy philosophy shape investment migration policy. The absence of nationality restrictions, unique among global programs, flows logically from Cambodia's commitment to neutrality and universal diplomatic engagement. This principled position creates theoretical opportunities for investors excluded elsewhere while generating significant practical challenges.

The program's future viability depends on navigating between principled neutrality and pragmatic international engagement. Enhanced transparency and operational improvements could address some concerns while preserving universal eligibility. Publishing statistics, establishing clear procedures, and creating dedicated processing infrastructure would demonstrate program integrity without compromising core principles.

For the global investment migration industry, Cambodia offers important lessons about the relationship between nationality restrictions and program success. While banned lists provide simple risk management tools and international credibility, they also represent crude instruments that may exclude legitimate investors based solely on birthplace. Cambodia's challenges stem less from accepting all nationalities than from operational deficiencies that would plague any program regardless of eligibility criteria.

Ultimately, Cambodia's CBI program occupies a unique niche—theoretically open to all but practically accessible to few, principled in design but problematic in implementation, valuable for specific purposes but limited in broader appeal. Whether this distinctive approach survives increasing international pressure remains uncertain, but its existence enriches understanding of how sovereignty, neutrality, and economic development intersect in the modern investment migration landscape.

For high-net-worth individuals considering Cambodia's CBI option, the message is clear: proceed with extreme caution, understand the unique risks including potential citizenship revocation, and carefully evaluate whether specific benefits like land ownership justify navigating an opaque process with an uncertain future. In an industry trending toward greater standardization and transparency, Cambodia's idiosyncratic approach offers both unique opportunities and exceptional challenges that demand careful consideration before commitment.
