Under what circumstances can U.S. citizens lose their citizenship?

U.S. citizens can be stripped of their citizenship if they committed fraud during their naturalization process, not simply for committing a crime. During the first Trump administration, there was a significant increase in the denaturalization office within the federal government, suggesting a more aggressive approach to this issue. While both Trump and potential Secretary of State Marco Rubio have acknowledged legal difficulties in deporting U.S. citizens abroad, there are established legal pathways for citizenship revocation. This becomes particularly relevant when discussing individuals with gang affiliations, as many of these gangs originated in the United States before spreading elsewhere.
