This is one of the businesses that’s choosing not to allow ICE inside their establishment unless they have a signed warrant from a Judge and this is starting to happen all over the Country! pic.twitter.com/dRw7hbWS3i

ICE can question or detain someone under immigration law without a criminal warrant, but they can’t just walk into private areas of a business without a judge’s warrant. The signs aren’t meaningless, they tell agents to stay out of nonpublic spaces unless they have real legal authority.
If ICE believes a criminal or undocumented person is inside, they still can’t enter private areas of a business or home without a judicial warrant signed by a judge. That’s protected under the Fourth Amendment.
They can:
-
Wait outside and question people leaving.
-
Enter public areas (like a store’s lobby or dining area).
-
Act if they see a crime in progress or get explicit consent from the owner to come in.
However:
-
They can’t go into employee-only sections, kitchens, or storage rooms without consent or a judicial warrant.
-
If the restaurant owner or staff asks them to leave, and they’re not actively pursuing someone or witnessing a crime, they’re expected to comply.
Federal law overrides state or local law when there’s a conflict. So if a federal law (like immigration enforcement under Title 8) contradicts a state or city policy (like a “sanctuary” rule or a business sign saying “ICE needs a warrant”), federal law wins.
But and this is important that clause applies to official state actions, not private property rules. A restaurant or business can legally limit access to private areas. ICE can still enforce federal law, but they can’t force entry into non-public areas without consent or a judicial warrant unless there’s probable cause or an emergency.
