When your record is expunged, the physical copies of your record are destroyed. Also, your name is removed from any index. Certain agencies can view your file, if you apply to work for them, including: 

• Law enforcement agencies
• The Department of Corrections
• The military

The State's Attorney and other prosecutors can review your juvenile record if you are charged with a new crime. Expungement does not require the physical destruction of internal office files, records, or databases maintained by the State’s Attorney or other prosecutors.

Law enforcement agencies cannot see your expunged record unless you’re applying to work for them.

Immigration officials may have access to erased records, or they may see that you had an arrest expunged. They cannot see the details of that arrest. Speak to a lawyer about how getting an arrest expunged could impact your immigration status.
