For the first time in two decades, the U.S. passport has dropped out of the world’s top 10 most powerful travel documents—now ranked 12th—prompting many to explore alternatives like European residency for US citizens. This shift highlights the changing landscape of global mobility, with countries offering Residency by Investment (RBI) programs, such as Portugal and Greece, ranked 6th, and Malta 7th, granting visa-free access to 186 and 185 destinations, respectively.
In this evolving landscape, American investors and high-net-worth individuals are rethinking their approach to global freedom of movement. They are increasingly exploring second citizenships and residency-by-investment programs as strategic tools to gain the unrestricted access guaranteed by European and Caribbean passports.
Increasing Demand for Second Passports
The decline of traditional mobility leaders, including the United States, in global passport rankings will lead more people to pursue Caribbean second citizenships and European residency for US citizens. Reasons such as the Schengen Area travel freedom, economic stability, political security, and improved lifestyle options are making European nations like Portugal, Greece, Malta, and Cyprus attract global investors to their investment-based residency and citizenship programs.
The number of American investors[1] who applied for second citizenship through investment migration programs reached its highest point in 2025 because of tightened visa regulations and growing worldwide political turbulence. The upcoming years will see an increase in investor applications because sufficient financial resources enable them to acquire passports through real estate purchases and local economic development initiatives.
People who want security now choose residency in Portugal for US citizens and other European Golden Visa programs as their preferred investment option. The programs let investors experience free travel while keeping their stability and global network access. Investors who participate in this program gain access to EU healthcare facilities and educational institutions, and investment opportunities.
A Closer Look at European Residency For Portugal
Portugal, along with Greece, emerged as a major victor in this situation. The Greek government[2] reported that the Golden Visa program attracted more American investors in 2024, thus establishing Greece as a preferred choice for US citizens and expatriates. The Greek Ministry of Immigration and Asylum[3] reported that American nationals received 353 residency permits throughout August 2024. The number of permits issued to Americans during August 2024 exceeded the 2023 numbers by 47%.
Interest in residency in Portugal for US citizens continues to grow , as the Portuguese government[4] processed 72% more applications through AIMA during the first half of 2025, with Americans receiving the majority of these approvals. The total number of Residence Permits[5] for investment activities reached 2,901 during 2023, while Americans received 567 of these permits.
In the first half of 2024, 81 applications to Antigua’s CIP came from US citizens out of 739 total applications, which represent about 10% of the total. In Grenada[6], 12% of the 402 people approved for citizenship by investment were Americans in Q2 2025. This is a steep increase from 1% in Q1 of the same year. By the end of June 2025, Grenada had approved 893 new citizens under its CBI/IMA program.

Reasons Why More Americans Are Choosing to Relocate
An increasing number of Americans from diverse backgrounds are exploring European residency for US citizens or pursuing second citizenships to gain greater security and an enhanced quality of life abroad. Below are the top reasons driving this growing trend:
- Tax Optimization
The US imposes taxes on its citizens based on their worldwide income, regardless of their place of residence. However, obtaining a second citizenship can present opportunities for tax optimization, particularly in nations that maintain more advantageous tax regimes.
US citizens encounter restrictions concerning offshore banking and financial services due to the FATCA (Foreign Account Tax Compliance Act). This means that renouncing US citizenship may be a viable option for individuals seeking to evade future tax liabilities. However, for high-net-worth individuals, such a decision activates the expatriation tax[7], often referred to as the exit tax. The latter applies to US citizens who choose to relinquish their citizenship and who meet any of the following conditions: possessing a net worth of $2 million, having an average annual net income tax liability that exceeds a particular threshold, or failing to certify compliance with all US federal tax obligations for the five years preceding the date of expatriation.
- Affordable cost of living
The high cost of living in the United States is prompting many to seek European residency for US citizens or alternative citizenship options abroad, as they look for more affordable lifestyles and better financial stability. People who retire, along with other individuals, relocate to nations that provide budget-friendly medical care, affordable housing, and reduced general cost of living. People who want their pension to stretch further choose to reside in Portugal, Greece, and Malta. These nations deliver identical living standards at budget-friendly rates, which make them more appealing than the United States.
- High Medical Expenses
High healthcare costs push Americans to seek better and more affordable options in other countries.
- Political & Social Tensions
Internal conflicts and a sense of dissatisfaction lead certain people to leave their home country and choose European residency for US citizens or other programs. The desire to escape US civil liberties concerns, economic instability, rising interest rates, inflation, and political polarization leads American citizens to seek citizenship or residency in foreign nations. Affluent Americans primarily choose to obtain a second citizenship because they want enduring stability, improved living standards, and financial protection.
- Retirement Savings
The decision to retire abroad has gained popularity among Americans because living expenses and healthcare costs continue to rise. European and Caribbean nations attract retirees who discover they can achieve a superior lifestyle through lower expenses compared to what they would spend in their home country. These nations welcome retirees, granting them both economic benefits and lifestyle perks, including comfortable weather, budget-friendly medical care, and engaging cultural activities.
- Desire for New Experiences
The number of Americans seeking second citizenship and residency permits through Caribbean and European programs has increased because these programs offer worldwide travel freedom, tax benefits, and improved lifestyle options. The combination of US political polarization with complex tax regulations and travel restrictions has motivated wealthy individuals to seek multiple citizenships. The programs allow citizens to obtain visa-free travel while providing them with investment opportunities and security in an unpredictable global environment.
