The Times' "Room for Debate" page took on the issue of dual citizenship, asking: "Can dual citizens be good Americans?" Yes, argued Peter Spiro, a professor at Temple's Beasley School of Law and an expert on immigration law and citizenship issues. "Dual citizenship is an irreversible incident of globalization. Its acceptance appropriately recognizes multiple national identities in a more mobile world," he wrote. "Dual citizenship represents a kind of freedom of association, a form of voluntary affiliation to be protected, not condemned."
