To prohibit sanctuary jurisdictions from receiving Federal funds under the State Criminal Alien Assistance Program, and for other purposes.

No Enforcement, No Grant for Sanctuary Cities Act of 2018 This bill prohibits a sanctuary jurisdiction from receiving federal funds under the state criminal alien assistance program for the fiscal year in which it was determined to be a sanctuary jurisdiction by the Department of Homeland Security (DHS). "Sanctuary jurisdiction" means a state or political subdivision that has a statute, ordinance, policy, or practice that prohibits or restricts a government entity or official from: sending, receiving, maintaining, or exchanging with a federal, state, or local government entity information regarding an individual's citizenship or immigration status; or cooperating with a lawful DHS request to comply with a detainer for or notification about an individual's release. A state or political subdivision shall not be deemed a sanctuary jurisdiction based solely on having a policy whereby its officials will not share information or cooperate with a DHS request to comply with a detainer for an individual who is a crime victim or witness.
