Section 1
SECTION 1. Any person whom the collector of customs of any port of the Philippine islands has reasonable ground to believe guilty of having aided, abetted, or incited insurrection in these Islands against the authority and sovereignty of the United States herein, or against the government constituted by the United States herein, or of coming to these Islands for that purpose, and who, coming from a foreign country, seeks to land at such port, shall not be permitted to land until after he shall take and subscribe before the collector or his authorized deputy the following oath: "I hereby solemnly swear that I acknowledge the sovereignty and authority of the United States in the Philippine Islands and of the government constituted by the United States herein, and that while in the Islands will support and maintain the same, and that I will not at any time hereafter or at any place aid, abet, or incite resistance to the authority of the United States or of the government established by the United States in these Islands, and that I take this oath voluntarily without any mental reservation whatsoever. So help me God." In case the person shall refuse to take, and subscribe such oath, he shall be detained in custody until the departure of the next steamer leaving for the port from which he last came, and then shall he deported at the expense of the Insular Government. The Collector of Customs may, while awaiting the sailing of the proper steamer, turn the person over to the police authorities of the port where the landing is sought to be made for safe custody.
