AdvertisementUnder his administration, Trump has made revoking someone’s citizenship, or denaturalization, a regular threat. People who are naturalized citizens can have their citizenship taken away in exceedingly rare but serious circumstances — and famous naturalized citizens have been the subject of Trump’s ire. AdvertisementWhat’s particularly concerning is that the government will typically file a civil lawsuit against you when it wants to take away your citizenship, Robertson noted. Trump’s political enemies like Musk and Mamdani have the resources to defend their citizenship, but the most vulnerable do not. But even if you don’t deal with this threat yourself, the potential threat is becoming more credible for naturalized citizens, because the Trump administration is pursuing cases on “minor idiosyncrasies and paperwork,” Robertson said.
