DSPS is finalizing registration in the federal SAVE program. This is a necessary step to help our agency verify ​Deferred Action for Childhood Arrivals (DACA) status as we implement legislation allowing eligible DACA recipients to obtain an occupational license in Wisconsin.

The SAVE program requires both DACA and employment authorization. DACA applicants should have their current Employment Authorization Document (EAD card) available to complete license application. ​
