730 ILCS 5/5-9-1.13
A person subject to conditions of probation, parole, or mandatory supervised release who seeks to transfer to another state subject to the Interstate Compact for Adult Offender Supervision must make provisions for the payment of any restitution awarded by the circuit court and pay a fee of $125 to the proper administrative or judicial authorities before being granted the transfer, or otherwise arrange for payment. The fee payment from persons subject to a sentence of probation shall be deposited into the general fund of the county in which the circuit has jurisdiction. The fee payment from persons subject to parole or mandatory supervised release shall be deposited into the General Revenue Fund. The proceeds of this fee shall be used to defray the costs of the Department of Corrections or county sheriff departments, respectively, who will be required to retrieve offenders that violate the terms of their transfers to other states. Upon return to the State of Illinois, these persons shall also be subject to reimbursing either the State of Illinois or the county for the actual costs of returning them to Illinois.
