The Justice Department is moving forward with Trump’s request to revoke the U.S. citizenship of hundreds of people who were born in foreign countries. DOJ officials are targeting nearly 400 U.S. citizens, calling it “the highest volume of denaturalization referrals in history.” These cases are extremely unusual, and denaturalization has so far only been pursued when a person is accused of obtaining U.S. citizenship through fraud or convicted of certain crimes. The naturalization process is extremely rigorous, and applicants are subjected to arduous vetting before even being approved.
