The wealthy are building “passport portfolios” — collections of second, and even third or fourth, citizenships — in case they need to flee their home country.
Recent high-profile examples of second citizenships include billionaire tech investor Peter Thiel, who added a citizenship in New Zealand, and former Google CEO Eric Schmidt, who applied for citizenship in Cyprus.
The top destinations for supplemental passports among Americans are Portugal, Malta, Greece and Italy, according to Henley & Partners.
