You're misconstruing what I said— nowhere in the constitution is a student visa a “right” to a citizen or not. But subjecting a non-citizen to a potentially unreasonable search while exempting regular citizens is likely against the 4th and 5th amendments (due process + unreasonable searches). Of course, “unreasonable” depends on the court’s interpretation.
Some Supreme Court decisions—
Bridges v. Wixon, 326 U.S. 135 (1945)
> freedom of speech and of press is accorded aliens residing in this country.
Plyler v. Doe, 457 U.S. 202 (1982)
> constitutional protections extend to “all persons” within the U.S, including undocumented immigrants.
