Proposing an amendment to the Constitution of the United States to prohibit persons who are not citizens, nationals, or lawful permanent residents of the United States from voting in elections.

H.J. Res. 31 proposes a constitutional amendment requiring all voters to be U.S. citizens, U.S. nationals, or lawful permanent residents (green card holders) for any election. This would prohibit non-citizens without national status or a green card from voting in federal, state, tribal, local, or territorial elections - including city council or school board races. The amendment must be ratified by 38 states (three-fourths of all states) within seven years to become part of the Constitution. Currently, most states already restrict voting to citizens, but this would extend that requirement nationwide and constitutionally.
