by CA state election law, a person's signature is proof of citizenship for voting. The registration affadavit says "under penalty of perjury" so no body would falsely claim they are a citizen to vote.
CA Elec Code § 2111 (2017)
A person may prove he or she is a citizen by his or her certification under penalty of perjury on the affidavit of registration.
CA Elec Code § 2112 (2017)
Notwithstanding any other provision of law to the contrary, the fact that a person certifies to his or her United States citizenship by signing his or her affidavit of registration shall be deemed evidence of citizenship for voting purposes only.

Think many states may have a similar statute, doubt any actually verify other than motor voter applications. Easy to falsify the claim of voter citizenship, just check a box and sign, with minimal risk of being caught. When fraud cases occur, don't hear about registration citizenship checks.
