Yes!! And if you're not register to vote in IL, GO REGISTER IN PERSON NOW!!
ALL YOU NEED IS TWO FORMS OF ID LIKE A DRIVERS LICENSE, STATE ID BUT IF YOU DON'T HAVE THOSE USE YOUR SCHOOL ID, SS, PASSPORT, or BILL WITH YOUR NAME ON IT!!
make sure you're living where you're living at for the past 30 days and bring proof of that also!
I brought my passport, school ID, ss and two bills (before 10/11/16) to register. Had to make sure I was going to vote 🇺🇸🇺🇸🇺🇸🇺🇸
