So far as the “declarant” of any nationality is concerned, it should be added that our Department of State has always sought to maintain that a declarant is in a position different from that of the ordinary alien, has extended a limited degree of protection, and now issues passports under the authority of an Act passed March 2, 1907--provided he has resided in the United States for three years; at the same time protecting itself from imposition by such persons by limiting the validity of such passports to a term of six months, and providing that an extended residence or domicile abroad shall be construed as an abandonment of the declared intention. Moreover, the naturalizing judges and the Bureau of Naturalization examine with great strictness the reasons for any absence whatever from the country after the declaration, and usually construe “intention” with regard to continuous residence with emphasis against the applicant. Many judges permit no absence, however brief, some going so far as to rule against any absence from the very county in which the applicant resides. And during the European War the issuance of such passports to natives of the belligerent countries was altogether suspended.[32] The United States was early committed not only by specific utterances and practices, but by the whole psychology and tradition of its being, to the principle of free expatriation; nevertheless, great confusion existed in the interpretation of the right as it related to efforts of American citizens to become citizens or subjects of other countries. The policy was finally crystallized in the Act of March 2, 1907, which provides definitely that “any American citizen shall be deemed to have expatriated himself when he has been naturalized in any foreign state in conformity with its laws, or when he has taken an oath of allegiance to any foreign state.” This is the Act which, in the same section, provides for the extension of naturalization by presumption upon two years’ residence in “the country from which he came,” or upon five years’ residence “in any foreign state.” But it is provided that “such presumption may be overcome on the presentation of satisfactory evidence to a diplomatic or consular officer of the United States, under such regulations as the Department of State may prescribe.” It is stipulated, however, that “no American citizen shall be allowed to expatriate himself when the country is at war.” During the Great War many American citizens imperiled, and in fact technically lost, their American citizenship by entering the military service of the various belligerent nations. After the entry of the United States into the conflict this was remedied by the enactment of Section 12 of the Act of May 9, 1918, in which it is provided that
