Reporting suspected illegal immigration is a very controversial issue within the United States; while some feel as though it is their civic responsibility to report alleged infractions of this kind, others choose to relinquish involvement - however, illegal immigration is considered to be a crime in the United States. Regardless of one’s respective beliefs in regard to illegal immigration, injustices towards human beings should always be reported to the local authorities. Although illegal immigration is considered to be a criminal act, illegal immigrants are human beings, regardless of their country of origin – as such, they are entitled to the respect, decency, and ethical treatment afforded to every citizen. In the event that one has witnessed the exploitation of an illegal immigrant by way of another individual – this can manifest itself in threat, abuse, violence, or blackmail – one is encouraged to contact the Office of Immigration and Customs Enforcement (ICE) at their toll-free phone number (866) 347-2423.
