The U.S. Department of Justice has filed suit to revoke the naturalized citizenship of Manuel Rocha, the former American diplomat exposed in 2023 as a long-running espionage asset of Communist Cuba. Not since Alger Hiss was unmasked as a Soviet spy has the State Department—and the nation—suffered such a profound betrayal by a senior diplomat.
Rocha was a Colombian-born immigrant who became a naturalized American citizen in his late 20s. Evidence suggests that Cuban intelligence recruited him before his naturalization and encouraged him to pursue a career in the U.S. Foreign Service. Yet beyond the outrage provoked by Rocha’s treason lies a broader concern: the question of divided loyalty in modern America.
After decades of mass immigration, approximately 25 million Americans are naturalized citizens. Many come from countries—like Mexico, the Philippines, and India—that continue to claim the allegiance of their nationals even after they acquire U.S. citizenship. The Mexican government is particularly aggressive, actively encouraging its expatriates in the United States to maintain political, cultural, and economic ties to the patria while simultaneously becoming Americans.
Although no official statistics exist, hundreds of thousands of federal employees in the national security bureaucracy are believed to hold dual citizenship, including an unknown number with access to classified information. The State Department has long attracted dual nationals, recruiting heavily among naturalized and first-generation Americans whose foreign-language skills and overseas experience are valuable diplomatic assets.
To be clear, the overwhelming majority of dual-national Americans are loyal citizens and bear no resemblance to Rocha. It should also be noted that the infamous Hiss and many other Cold War spies emerged from the heart of the American middle class, not from immigrant communities. Espionage will always remain a threat, and no vetting system can eliminate it entirely.
Yet decades of multiculturalism and unassimilated immigration have introduced a subtler challenge: government officials whose attachments to another nation may influence their judgment, create conflicts of interest, or leave them vulnerable to foreign pressure. Even when loyalty to the United States is unquestioned, secondary allegiances can complicate decision-making in sensitive positions.
