Miller Mayer immigration attorney Steve Yale-Loehr was quoted by Verify This in No, the President Can’t Completely Close the Border by Executive Order. The article notes that some people, including House Speaker Mike Johnson, have cited section 212(f) of the Immigration and Nationality Act “when claiming Biden has the authority to shut down the border via executive action.” Steve noted that federal law does give the president broad powers to suspend the entry of certain noncitizens who are “detrimental to the interests of the United States,” but that “doesn’t mean [the President] can just shut the border.”
