All people living in the United States, regardless of
immigration status, have certain U.S. constitutional rights. If
Immigration and Customs Enforcement (ICE) officers come to your
workplace, they must have either (1) a valid search warrant, or (2)
consent from your employer to enter non-public areas. Non-public
areas could include: staff break rooms, server rooms, mechanical
rooms, HR department offices, private meeting rooms, etc. However,
ICE can enter public areas of your workplace (lobby, reception
area, parking lot etc.) without a warrant or consent from your
employer.
If you encounter ICE at your place of employment, it is
important to stay calm. If an officer stops you,
you may ask if you are free to leave. If they say yes, walk away
calmly. If they say no, stay where you are and do not attempt to
leave.
