Just putting a note here that whether or not foreign nationals are subject to the protections of the Constitution is a contentious issue. IANAL, but in many places the Constitution specifically calls out citizens vs non-citizens and in other places does not make an explicit distinction. The bill of rights is one place it doesn't explicitly specify, and indeed uses language that elsewhere was used to indicate it applying to citizens and non-citizens. Of course that interpretation fell away during the cold war and is less popular now.
