WHO ARE ELIGIBLE FOR NATURALIZATION
Naturalization is a privilege to be given, qualified, or withheld as Congress may determine, which an alien may claim only upon compliance with the terms which Congress imposes. Earlier the privilege was confined to white persons and persons of African descent, but was extended by the Act of December 17, 1943, to descendants of races indigenous to the Western Hemisphere and Chinese persons or persons of Chinese descent;[1049] and by the Act of June 27, 1952, "the rights of a person to become a naturalized citizen of the United States shall not be denied or abridged because of race or sex or because the person is married."[1050] But, any person "who advocates or teaches or who is a member of or affiliated with any organization that advocates or teaches * * *" opposition to all organized government, or "who advocates or teaches or who is a member of or affiliated with any organization that advocates or teaches the overthrow by force or violence or other unconstitutional means of the Government of the United States" may not be naturalized as a citizen of the United States.[1051] These restrictive provisions are, moreover, "applicable to any applicant for naturalization who at any time within a period of ten years immediately preceding the filing of the petition for naturalization or after such filing and before taking the final oath of citizenship is, or has been found to be within any of the classes enumerated within this section, notwithstanding that at the time the petition is filed he may not be included within such classes."[1052]
THE PROCEDURE OF NATURALIZATION
This involves as its principal and culminating event the taking in open court by the applicant of an oath: "(1) to support the Constitution of the United States; (2) to renounce and abjure absolutely and entirely all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty of whom or which the petitioner was before a subject or citizen; (3) to support and defend the Constitution and the laws of the United States against all enemies, foreign and domestic; (4) to bear true faith and allegiance to the same; and (5)(A) to bear arms on behalf of the United States when required by the law, or (B) to perform noncombatant service in the Armed Forces of the United States when required by the law, or (C) to perform work of national importance under civilian direction when required by law."[1053] Any naturalized person who takes this oath with mental reservations or conceals beliefs and affiliations which under the statute disqualify one for naturalization, is subject, upon these facts being shown in a proceeding brought for the purpose, to have his certificate of naturalization cancelled.[1054] Furthermore, if a naturalized person shall within five years "following his naturalization become a member of or affiliated with any organization, membership in or affiliation with which at the time of naturalization would have precluded such person from naturalization under the provisions of section 313, it shall be considered prima facie evidence that such person was not attached to the principles of the Constitution of the United States and was not well disposed to the good order and happiness of the United States at the time of naturalization, and, in the absence of countervailing evidence, it shall be sufficient in the proper proceeding to authorize the revocation and setting aside of the order admitting such person to citizenship and the cancellation of the certificate of naturalization as having been obtained by concealment of a material fact or by willful misrepresentation. * * *" [1055]
RIGHTS OF NATURALIZED PERSONS
Chief Justice Marshall early stated the dictum that "a naturalized citizen * * * become a member of the society, possessing all the rights of a native citizen, and standing, in the view of the Constitution, on the footing of a native. The Constitution does not authorize Congress to enlarge or abridge those rights. The simple power of the national legislature is, to prescribe a uniform rule of naturalization, and the exercise of this power exhausts it, so far as respects the individual."[1056] A similar idea was expressed in 1946 in Knauer v. United States:[1057] "Citizenship obtained through naturalization is not a second-class citizenship. * * * [It] carries with it the privilege of full participation in the affairs of our society, including the right to speak freely, to criticize officials and administrators, and to promote changes in our laws including the very Charter of our Government."[1058] But, as shown above, a naturalized citizen is subject at any time to have his good faith in taking the oath of allegiance to the United States inquired into, and to lose his citizenship if lack of such faith is shown in proper proceedings.[1059] Also, "a person who has become a national by naturalization" may lose his nationality by "having a continuous residence for three years in the territory of a foreign state of which he was formerly a national or in which the place of his birth is situated," or by "having a continuous residence for five years in any other foreign state or states."[1060] However, in the absence of treaty or statute to the contrary effect, a child born in the United States who is taken during minority to the country of his parents' origin, where his parents resume their former allegiance, does not thereby lose his American citizenship provided that on attaining his majority he elects to retain it and returns to the United States to assume its duties.[1061]
Congress' power over naturalization is an exclusive power. A State cannot denationalize a foreign subject who has not complied with federal naturalization law and constitute him a citizen of the United States, or of the State, so as to deprive the federal courts of jurisdiction over a controversy between him and a citizen of a State.[1062] But power to naturalize aliens may be, and early was, devolved by Congress upon state courts having a common law jurisdiction.[1063] Also States may confer the right of suffrage upon resident aliens who have declared their intention to become citizens, and have frequently done so.[1064]
RIGHT OF EXPATRIATION: LOSS OF CITIZENSHIP
Notwithstanding evidence in early court decisions[1065] and in the Commentaries of Chancellor Kent of a brief acceptance of the ancient English doctrine of perpetual and unchangeable allegiance to the government of one's birth, whereby a citizen is precluded from renouncing his allegiance without permission of that government, the United States, since enactment of the act of 1868,[1066] if indeed not earlier, has expressly recognized the right of everyone to expatriate himself and choose another country. Retention of citizenship is not dependent entirely, however, upon the desires of the individual; for, although it has been "conceded that a change of citizenship cannot be arbitrarily imposed, that is, imposed without the concurrence of the citizen," the United States, by virtue of the powers which inhere in it as a sovereign nation, has been deemed competent to provide that an individual voluntarily entering into certain designated conditions shall, as a consequence thereof, suffer the loss of citizenship.[1067]
