Citizenship by Investment for U.S. Citizens: What You Need to Know in 2026

Introduction

American citizens are seeking second passports in record numbers. Driven by political polarisation, concerns over global travel restrictions, and a desire for a credible Plan B, U.S.-based high-net-worth individuals and families are turning to citizenship by investment as a strategic asset. Yet acquiring a second citizenship as an American comes with unique considerations that do not apply to applicants from other countries. From the legality of dual citizenship under U.S. law to the complex tax obligations that follow American citizens worldwide, the decision requires careful planning and expert guidance. This guide covers everything U.S. citizens need to know about citizenship by investment in 2026 — the rules, the tax realities, the best programs for Americans, and how to navigate the application process with confidence.

Can U.S. Citizens Hold Dual Citizenship?

Yes — dual citizenship is fully legal under United States law. The U.S. government does not require citizens to renounce their American citizenship when acquiring a second nationality, nor does obtaining a foreign passport affect your U.S. citizenship status. The Supreme Court has consistently upheld the right of Americans to hold multiple citizenships simultaneously. You will continue to enter and exit the United States on your U.S. passport, while using your second passport for travel to other countries. It is worth noting that the U.S. State Department does not formally "recognise" dual citizenship as a legal status, but it acknowledges its existence and does not penalise it. There are no filing requirements triggered solely by becoming a citizen of another country. However, if your second citizenship comes with financial accounts, investments, or income abroad, additional reporting obligations may apply — which brings us to the critical topic of taxation.

Tax Implications for U.S. Citizens

The United States is one of only two countries in the world that taxes its citizens on worldwide income, regardless of where they live. This means that acquiring a second citizenship does not change your U.S. tax obligations in any way. You remain subject to federal income tax, capital gains tax, and estate tax on your global assets. Additionally, U.S. citizens with foreign financial accounts exceeding $10,000 in aggregate at any point during the year must file a Report of Foreign Bank and Financial Accounts (FBAR) with FinCEN. If your CBI investment involves foreign financial assets above certain thresholds, you may also be subject to reporting under the Foreign Account Tax Compliance Act (FATCA) via IRS Form 8938. These obligations are reporting requirements, not additional taxes — but non-compliance carries severe penalties. We strongly recommend working with a cross-border tax advisor who understands both CBI structuring and U.S. tax law to ensure full compliance from the outset.

Best CBI Programs for Americans

Three Caribbean CBI programs are particularly popular among U.S. citizens, each for distinct strategic reasons. Grenada stands apart as the only CBI nation with an E-2 Treaty with the United States, allowing Grenadian citizens to apply for the U.S. E-2 Investor Visa — a powerful tool for entrepreneurs and families who want the flexibility to live and operate a business in the U.S. under a separate legal framework. Saint Kitts & Nevis, the world's oldest CBI program, offers the most established and widely trusted passport, with visa-free access to over 157 countries and a four-decade track record of institutional credibility. Dominica provides the most cost-effective pathway, with donations starting at $200,000 and consistently top rankings on the CBI Index for due diligence and processing speed. Many American families apply to one or more of these programs simultaneously, depending on their travel needs, business interests, and long-term planning goals.

The Application Process

The CBI application process for U.S. citizens follows the same framework as for any other nationality, with a few additional documentation considerations. The journey begins with a confidential consultation to assess eligibility, define objectives, and select the optimal program. From there, our team prepares a comprehensive application package, which typically includes certified copies of your U.S. passport, birth certificate, marriage certificate (if applicable), bank reference letters, a professional background summary, and a clean police clearance from every jurisdiction where you have lived for more than one year. U.S. applicants should budget additional time for FBI background checks, which are a standard requirement across all Caribbean CBI programs. Once submitted, applications undergo government-level due diligence — a rigorous vetting process conducted by international agencies — followed by an approval decision, investment completion, and passport issuance. End-to-end, most American applicants receive their second passport within three to six months of filing.
