Does Illinois punish out of state DUIs more than in state DUI when it comes to license reinstatement?

As a drivers license lawyer in Illinois who has handled hundreds of license reinstatement issues to a successful resolution, I find that there is a situation where people who are trying to get their license back because they were revoked for DUI are treated more harshly by the Illinois Secretary of State then those who have the exact same number of DUI arrests. This happens when a person who has an Illinois drivers license is arrested outside the state of Illinois. For example, if a person is arrested in Illinois for a DUI with an Illinois drivers license, they will be granted to court supervision, which is not a conviction and does not revoke their license in the State of Illinois in 99% of the cases.  On the other hand, a person with an Illinois drivers license who is arrested and charged with a DUI in Wisconsin or Indiana or any other state Will most likely have their license to drive in Illinois revoked if they are found guilty of the offense in that state. This happens because Illinois does not treat the out-of-state DUI like they treat an in-state DUI first offense. Therefore, I often tell my license reinstated my clients that a first offense outside the state of Illinois might as well be a second offense in Illinois as we have to prepare them for a Secretary of State administrative hearing.
