Should proof of citizenship be required to vote in elections?

Context

Proof of citizenship requirements for voting are a contested policy issue in American elections. Supporters argue such requirements prevent non-citizens from voting and strengthen election integrity, while opponents contend they create barriers for eligible citizens and that non-citizen voting is extremely rare. The debate has intensified recently, with some states implementing new requirements while courts in others have struck them down, reflecting broader disagreements about balancing ballot access with election security.
