Title 18 › PART I — CRIMES › CHAPTER 27 — CUSTOMS › § 555
Making or paying for an underground tunnel that crosses the U.S. border is a federal crime, unless it is an authorized tunnel the Secretary of Homeland Security knows about and ICE can inspect. Knowingly doing this can bring fines and up to 20 years in prison. Owners who know or recklessly ignore a tunnel on their land can be fined and face up to 10 years. Using such a tunnel to smuggle people or banned items (including goods in violation of section 545, drugs, weapons of mass destruction, or members of terrorist groups as defined in section 2339B(g)(6)) doubles the prison maximum that would otherwise apply. Trying or planning these crimes brings the same penalties as actually doing them.
