Concealing or Harboring Aliens is a federal offense in the United States. It is defined as knowingly concealing, harboring, shielding from detection, or transporting an alien who is in the United States illegally. This act can be committed by individuals, companies, or organizations, and can involve assisting an alien with avoiding detection by Immigration and Customs Enforcement (ICE) officials. There are two types of Concealing or Harboring Aliens: 1. Passive Concealing or Harboring: This type of concealment or harboring involves providing an alien with shelter or assistance, such as providing the alien with food, money, or transportation, without the intent to violate immigration laws. 2. Active Concealing or Harboring: This type of concealment or harboring involves actively helping an alien evade or obstruct the enforcement of immigration laws, such as providing false documents or harboring an alien in a residence or place of business. If convicted of Concealing or Harboring Aliens, individuals may face up to 10 years in prison, a fine up to $250,000, or both. Companies or organizations may face fines up to $500,000.
