Steve was quoted by Time in What to Know About Mahmoud Khalil, and Why His Green Card Was Revoked. He noted that although green card holders have many of the same rights as U.S. citizens, they can still face deportation under certain conditions, typically for criminal behavior or violations of immigration law. Foreign nationals can also lose their visas for endorsing or associating with terrorist groups, but only if the government can provide material evidence, he noted. “The government would need to prove that he’s done something more than just speaking out, like offering material support to Hamas. That would be a ground of deportability. They can’t deport only for free speech advocacy.”
