Citizenship is an essential component required for the privilege of voting in the U.S. With the current mainstream political effort to allow non-citizens access to all kinds of government benefits, voting access is also being promoted. When a person registers to vote, the application form includes a section in which they verify they are a US citizen. It is essentially an affidavit.
There is no verification of this by election officials thereafter. E-verify is a federal database used to determine a worker’s authorization to work in the U.S. It does not provide immigration or citizenship status. Non-citizen verification should be utilized via the USCIS SAVE Database.
