No.

There is no evidence that 10,000 undocumented immigrants voted illegally using a single social security number in Arizona’s 2020 election. Undocumented immigrants cannot vote in U.S. elections. Only U.S. citizens are eligible to vote, with the exception of a few municipalities that allow non-citizen voting in local elections.
Non-citizens with lawful resident status may possess a valid social security number under some circumstances, but this does not make them eligible to vote.
Arizona law requires individuals to submit proof of citizenship with their voter registration to be eligible for state and local elections. To vote in federal elections, individuals must certify under penalty of perjury that they are a U.S. citizen. Non-citizens risk jail time or deportation for fraudulent registration. Studies have found instances of non-citizen voter registration to be exceptionally rare.
