Requirements of naturalization

No person, except as otherwise provided in this subchapter, shall be naturalized unless such applicant, (1) immediately preceding the date of filing his application for naturalization has resided continuously, after being lawfully admitted for permanent residence, within the United States for at least five years and during the five years immediately preceding the date of filing his application has been physically present therein for periods totaling at least half of that time, and who has resided within the State or within the district of the Service in the United States in which the applicant filed the application for at least three months, (2) has resided continuously within the United States from the date of the application up to the time of admission to citizenship, and (3) during all the periods referred to in this subsection has been and still is a person of good moral character, attached to the principles of the Constitution of the United States, and well disposed to the good order and happiness of the United States. Absence from the United States of more than six months but less than one year during the period for which continuous residence is required for admission to citizenship, immediately preceding the date of filing the application for naturalization, or during the period between the date of filing the application and the date of any hearing under section 1447(a) of this title, shall break the continuity of such residence, unless the applicant shall establish to the satisfaction of the Attorney General that he did not in fact abandon his residence in the United States during such period. Absence from the United States for a continuous period of one year or more during the period for which continuous residence is required for admission to citizenship (whether preceding or subsequent to the filing of the application for naturalization) shall break the continuity of such residence, except that in the case of a person who has been physically present and residing in the United States, after being lawfully admitted for permanent residence, for an uninterrupted period of at least one year, and who thereafter is employed by or under contract with the Government of the United States or an American institution of research recognized as such by the Attorney General, or is employed by an American firm or corporation engaged in whole or in part in the development of foreign trade and commerce of the United States, or a subsidiary thereof more than 50 per centum of whose stock is owned by an American firm or corporation, or is employed by a public international organization of which the United States is a member by treaty or statute and by which the alien was not employed until after being lawfully admitted for permanent residence, no period of absence from the United States shall break the continuity of residence if— The granting of the benefits of subsection (b) of this section shall not relieve the applicant from the requirement of physical presence within the United States for the period specified in subsection (a) of this section, except in the case of those persons who are employed by, or under contract with, the Government of the United States. In the case of a person employed by or under contract with Central Intelligence Agency, the requirement in subsection (b) of an uninterrupted period of at least one year of physical presence in the United States may be complied with by such person at any time prior to filing an application for naturalization. No finding by the Attorney General that the applicant is not deportable shall be accepted as conclusive evidence of good moral character. In determining whether the applicant has sustained the burden of establishing good moral character and the other qualifications for citizenship specified in subsection (a) of this section, the Attorney General shall not be limited to the applicant’s conduct during the five years preceding the filing of the application, but may take into consideration as a basis for such determination the applicant’s conduct and acts at any time prior to that period.
