Back on May 9, I suggested that a future post on whether the Fifth Amendment’s guarantee against self-incrimination applies to non-citizens abroad was forthcoming. Though I’ve been a bit distracted by trial the last few weeks, I have not forgotten that commitment.
As a general matter, foreign nationals outside the United States are not entitled to constitutional protections, including due process protections. This limitation might extend to non-citizens interrogated abroad by U.S. law enforcement, or non-citizens without status in the United States giving interviews to U.S. consular officials in an effort to obtain a visa. But there’s a good case for arguing that the right against self-incrimination embedded within the Fifth Amendment’s text would preclude the use of any incriminating statements given without procedural warnings in a subsequent criminal prosecution. Such an argument would not depend on an extraterritorial application of the Fifth Amendment, but rather a domestic one.
