A study by Rutgers University analyzing nuclear fallout risks in the event of a global conflict identifies South America, Australia, and New Zealand as regions with the highest chance of survival due to lower projected starvation percentages during a nuclear winter. While Australia and New Zealand present significant residency and citizenship barriers for non-wealthy individuals, several South American nations offer viable alternative residencies and passports as contingency options.
Brazil
Permanent residency in Brazil can be obtained through an investment of approximately $100,000 USD. While naturalized Brazilian citizens generally face strict protections against foreign extradition, the government has historically extradited citizens in serious criminal cases.
- Birthright Citizenship: Brazil grants automatic citizenship by birth. High-quality healthcare options exist, such as the Albert Einstein Hospital in São Paulo, which is frequently used by foreign nationals for birth tourism.
- Safety: Security risks vary significantly by region. São Paulo and Florianópolis are considered safer alternatives to Rio de Janeiro, though safety precautions (such as utilizing security or armored transport) remain common in major hubs.
Argentina
Argentina offers one of the fastest paths to citizenship globally, allowing individuals to qualify for a passport after two years of residency. The permanent residency program requires an investment ranging between $50,000 and $100,000 USD. Like Brazil, Argentina grants automatic citizenship to children born within its territory. Permanent residency can be maintained through intermittent visits without full-time physical relocation.
Uruguay
Considered a highly stable and secure option within the region, Uruguay provides robust nuclear fallout protection and a strong passport. The country offers temporary tax exemptions that can reduce liability to between 10% and 20%, though it does not operate as a completely tax-free jurisdiction.
Tax Considerations
None of these South American nations are zero-tax jurisdictions. Argentina, Brazil, and Uruguay enforce significant tax structures, unlike hubs such as the United Arab Emirates. To avoid triggering local tax liabilities while securing a backup location, strategies typically rely on maintaining the residency as a secondary option (“Plan B”) rather than establishing a long-term, tax-resident home base.
