Ummm. It would have its status changed to Inactive if you didn't pay.
In most states you can just mail them a form saying you want to be Inactive because you don't want to pay the fee for renewal. People do this if they move and they eventually realize they don't want to ever move back to the original state.
I believe the only issue is that you don't want to "Inactive" status your license in the state you are licensed by "Examination".
IE: You go to school in Michigan. You get original licensure in MI by Examination. After 4 years you move to Iowa and get licensed by Reciprocity. After 2 years you move to Wisconsin. You can go Inactive with your license in Iowa but not Michigan, because it is Michigan that you are licensed by Examination.
