What the Evidence Shows

Claims regarding widespread voting by noncitizens in federal elections are flatly unsupported by empirical evidence and official oversight.

Furthermore, federal law explicitly prohibits noncitizens from voting in federal elections, carrying heavy criminal penalties, significant fines, and guaranteed immigration consequences such as deportation.
