A Capuchin Franciscan and a former priest are among 10 people who have been stripped of their U.S. citizenship because of crimes committed before their naturalisation, the U.S. Department of Homeland Security (DHS) and the Department of Justice announced last week.

"When you commit fraud during the naturalisation process, you forfeit the right to keep your U.S. citizenship," said DHS Secretary Markwayne Mullin in a July 22 press release.

Mullin continued: "These criminal aliens, comprised of drug traffickers, pedophiles and fraudsters, lost that right and exploited our immigration system — harming real U.S. citizens. DHS is committed to ensuring we denaturalise and remove these fraudsters with every tool at our disposal."
