If I have residency in one state (CA) and have a valid drivers license in IL, if I go back to IL and get my license renewed, will it cancel out my current residency in CA?

State laws typically stipulate that a drivers license may only be renewed in the current state of residency. And they typically require that you get a new license within 30 days of change in residency. YMMV.

So, if you walk into the IL DMV and request a license addressed in Compton, chances are they’re gonna tell you no.

What state do you pay taxes to? Also, robmandu is very correct about being required to get a new license in the state you took up residency in.

How long have you lived in California? You may have up to 30 days from establishing residence in this state to obtain a driver’s license, and if you don’t do it you’re unlicensed in this state. That allows law enforcement to tow your vehicle.

I have a similar situation to you. I renew my driver’s Licesne in Florida, but I live in New Jersey. If I ever get pulled over, I would get a huge fine, but it doesn’t affect my residency status in New Jersey as far as filing taxes, etc.
