With respect to a nonparty to the Vienna Convention, the mission, the members of the mission, their families, and diplomatic couriers shall enjoy the privileges and immunities specified in the Vienna Convention.

Any action or proceeding brought against an individual who is entitled to immunity with respect to such action or proceeding under the Vienna Convention on Diplomatic Relations, under section 254b or 254c of this title, or under any other laws extending diplomatic privileges and immunities, shall be dismissed. Such immunity may be established upon motion or suggestion by or on behalf of the individual, or as otherwise permitted by law or applicable rules of procedure.

Whenever it is stipulated by treaty or convention between the United States and any foreign nation that the consul general, consuls, vice consuls, or consular or commercial agents of each nation, shall have exclusive jurisdiction of controversies, difficulties, or disorders arising at sea or in the waters or ports of the other nation, between the master or officers and any of the crew, or between any of the crew themselves, of any vessel belonging to the nation represented by such consular officer, such stipulations shall be executed and enforced within the jurisdiction of the United States as declared in sections 257 and 258 of this title. But before this section shall take effect as to the vessels of any particular nation having such treaty with the United States, the President shall be satisfied that similar provisions have been made for the execution of such treaty by the other contracting party, and shall issue his proclamation to that effect, declaring this section to be in force as to such nation.

In all cases within the purview of section 256 of this title the consul general, consul, or other consular or commercial authority of such foreign nation charged with the appropriate duty in the particular case, may make application to any court of record of the United States, or to any judge thereof, or to any United States magistrate judge, setting forth that such controversy, difficulty, or disorder has arisen, briefly stating the nature thereof, and when and where the same occurred, and exhibiting a certified copy or extract of the shipping articles, roll, or other proper paper of the vessel, to the effect that the person in question is of the crew or ship’s company of such vessel; and further stating and certifying that such person has withdrawn himself, or is believed to be about to withdraw himself, from the control and discipline of the master and officers of the vessel or that he has refused, or is about to refuse, to submit to and obey the lawful jurisdiction of such consular or commercial authority in the premises; and further stating and certifying that, to the best of the knowledge and belief of the officer certifying, such person is not a citizen of the United States. Such application shall be in writing and duly authenticated by the consular or other sufficient official seal. Thereupon such court, judge, or magistrate judge shall issue his warrant for the arrest of the person so complained of, directed to the marshal of the United States for the appropriate district, or in his discretion to any person, being a citizen of the United States, whom he may specially depute for the purpose, requiring such person to be brought before him for examination at a certain time and place.

If, on such examination, it is made to appear that the person so arrested is a citizen of the United States, he shall be forthwith discharged from arrest, and shall be left to the ordinary course of law. But if this is not made to appear, and such court, judge, or magistrate judge finds, upon the papers referred to in section 257 of this title, a sufficient prima facie case that the matter concerns only the internal order and discipline of such foreign vessel, or whether in its nature civil or criminal, does not affect directly the execution of the laws of the United States, or the rights and duties of any citizen of the United States, he shall forthwith, by his warrant, commit such person to prison, where prisoners under sentence of a court of the United States may be lawfully committed, or, in his discretion, to the master or chief officer of such foreign vessel, to be subject to the lawful orders, control, and discipline of such master or chief officer, and to the jurisdiction of the consular or commercial authority of the nation to which such vessel belongs, to the exclusion of any authority or jurisdiction in the premises of the United States or any State thereof. No person shall be detained more than two months after his arrest, but at the end of that time shall be set at liberty and shall not again be arrested for the same cause. The expenses of the arrest and the detention of the person so arrested shall be paid by the consular officers making the application: Provided, That nothing in this section or section 257 of this title shall authorize the arrest or imprisonment of officers and seamen deserting or charged with desertion from merchant vessels of foreign nations in the United States and Territories and possessions thereof, and the cooperation, aid, and protection of competent legal authorities in effecting such arrest or imprisonment.

The district courts and the United States magistrate judges shall have power to carry into effect, according to the true intent and meaning thereof, the award or arbitration or decree of any consul, vice consul or commercial agent of any foreign nation, made or rendered by virtue of authority conferred on him as such consul, vice consul, or commercial agent, to sit as judge or arbitrator in such differences as may arise between the captains and crews of the vessels belonging to the nation whose interests are committed to his charge, application for the exercise of such power being first made to such court or magistrate judge, by petition of such consul, vice consul, or commercial agent. And said courts and magistrate judges may issue all proper remedial process, mesne and final, to carry into full effect such award, arbitration, or decree, and to enforce obedience thereto by imprisonment in the jail or other place of confinement in the district in which the United States may lawfully imprison any person arrested under the authority of the United States, until such award, arbitration or decree is complied with, or the parties are otherwise discharged therefrom, by the consent in writing of such consul, vice consul, or commercial agent, or his successor in office, or by the authority of the foreign government appointing such consul, vice consul, or commercial agent. The expenses of the said imprisonment and maintenance of the prisoners, and the cost of the proceedings, shall be borne by such foreign government, or by its consul, vice consul, or commercial agent requiring such imprisonment. The marshals of the United States shall serve all such process, and do all other acts necessary and proper to carry into effect the premises, under the authority of the said courts and magistrate judges.
