20 (iv) reaches some expression that is outside the speech-integral-to-unlawful-conduct exception. Of course, “that speech is not categorically unprotected does not mean it is immune from regulation, but only that ordinary First Amendment scrutiny would apply.” Brief for Respondent 44.

We need not address this novel theory, because even if Hansen is right, his overbreadth challenge fails. To succeed, he has to show that clause (iv)’s overbreadth is “substantial … relative to [its] plainly legitimate sweep.” Williams, 553 U. S., at 292. As we have discussed, the provision has a wide legitimate reach insofar as it applies to nonexpressive conduct and speech soliciting or facilitating criminal violations of immigration law. Even assuming that clause (iv) reaches some protected speech, and even assuming that its application to all of that speech is unconstitutional, the ratio of unlawful-to-lawful applications is not lopsided enough to justify the “strong medicine” of facial invalidation for overbreadth. Broadrick v. Oklahoma, 413 U. S. 601, 613 (1973). In other words, Hansen asks us to throw out too much of the good based on a speculative shot at the bad. This is not the stuff of overbreadth—as-applied challenges can take it from here.

The judgment of the Ninth Circuit is reversed, and the case is remanded for further proceedings consistent with this opinion. It is so ordered.
