How do i become a residence of the Arizona ?|160731

I_m moving to Phoenix, to attend ASU. I_m 18 years old now and a German citizen, and will be paying my own bills, apartment, and i contacted DMV, and they told me to change the EU drivers license after 6 months , to some state drivers license what i believe, since ill be staying there for at least 5 years, also because of Uni. I_m not wanting to move back to anywhere else. How will i gain residency in Arizona ?

if you want to stay in the US you will need to get your visa changed from student to permanent resident. then you can establish residency in Arizona.
