If someone calls ICE on you, it means that they have reported you to the US Immigration and Customs Enforcement agency. This can happen if they believe that you are in the country illegally, or if you have committed a crime. If ICE does come to arrest you, they will take you into custody and start the process of deportation. However, this does not always mean that you will be deported – it depends on your individual case. You may be able to fight your deportation in court, or apply for asylum if you fear persecution in your home country.
