My experience is that in getting a state ID, you need birth certificate or another document.
In the case of a state without voter ID, there is no check — you literally just have to bring an electric bill. A non citizen could easily vote. It would be illegal, but the odds of being caught are slim to none.
If there was a suspicion that the voter was illegal, a poll worker could have them cast a provisional ballot. In places like California, it is a felony to require a provisional ballot without evidence.
