California does not want you looking too closely at who is helping run its elections. Green card holders as young as 16 can check voters off official rosters, distribute ballots, handle election equipment, and help close polling locations. The state admits it does not fully track how many are being used.

These students are not being enlisted to hand out stickers or direct voters toward the entrance. County election agencies say they may issue ballots, check voters off official rosters, help operate election equipment, assist voters throughout the day, prepare ballots for pickup, and participate in closing polling locations. In other words, California has made citizenship optional for the people performing frontline election duties.
