If you follow the news at all, you have heard of ICE, U.S. Immigration and Customs Enforcement, which is the agency responsible for detaining and removing those foreign nationals who are in the country unlawfully. ICE receives a great deal of media coverage for its raids to capture and deport immigrants unlawfully present here. While this is only part of the work of this agency, if you encounter ICE, you are right to have concerns for your future.
