The question of whether a U.S. president possesses the authority to deport a sitting member of Congress who is a naturalized citizen has surfaced in political commentary. Representative Ilhan Omar, who was born in Somalia and became a naturalized U.S. citizen in 2000, has been the subject of such rhetoric.

Under the 14th Amendment of the U.S. Constitution, naturalized citizens are afforded the same protections as native-born citizens. Legal scholars emphasize that citizenship, once granted, cannot be revoked by executive order. The process of denaturalization is a rigorous judicial proceeding that can only occur if the government proves that an individual committed fraud during their naturalization application. Even in cases of successful denaturalization, the individual would then be subject to standard immigration removal proceedings, which are governed by federal law and subject to judicial review.

While some political figures have suggested the possibility of deportation as a punitive measure for political speech or perceived disloyalty, there is no legal mechanism in the United States that allows for the deportation of a citizen based on political disagreement or executive preference. The executive branch lacks the unilateral power to strip a citizen of their status or remove them from the country, as these powers are strictly limited by the Constitution and federal statutes.
