I have an office in Maryland and ICE is quite an active enforcer. They may do nothing especially if your employer called the USCIS 800# or the state of Maryland to confirm ability to hire you. However, if he is an e-verify employer, your risk may incdrease. There are many people in Maryland who gets knocks on the door from ICE.
Consider consulting with a competent lawyer.
