Any person who is an applicant under sections 316, 319, 324, 325, 327, 328, 329, or 330 of the Act and the corresponding parts of this chapter, may apply for naturalization in accordance with the procedures prescribed in this chapter in accordance with the instructions on the form.

(a) An applicant may file an application for naturalization with required initial evidence in accordance with the general form instructions for naturalization. The applicant must include the fee as required in 8 CFR 106.2.

(b) An application for naturalization may be filed up to 90 days prior to the completion of the required period of residence, which may include the three-month period of residence required to establish jurisdiction under section 316(a) or 319(a) of the Act.

Whenever it appears that an applicant for naturalization may be unable, because of sickness or other disability, to appear for the initial examination on the application or for any subsequent interview, the district director shall cause an investigation to be conducted to determine the circumstances surrounding the sickness or disability. The district director shall determine, based on available medical evidence, whether the sickness or disability is of a nature which so incapacitates the applicant as to prevent the applicant's appearance at a Service office having jurisdiction over the applicant's place of residence. If so, the district director shall designate another place where the applicant may appear for the requisite naturalization proceedings.

(a) Clerical amendments—(1) By applicant. An applicant may request that the application for naturalization be amended either prior to or subsequent to the administration of the oath of allegiance.

(2) By Service. The Service may amend, at any time, an application for naturalization when in receipt of information that clearly indicates that a clerical error has occurred.

(3) Amendment procedure. Any amendment will be limited to the correction of clerical errors arising from oversight or omission. If the amendment is approved, the amended application shall be filed with the original application for naturalization.

(b) Substantive amendments. Any substantive amendments which affect the jurisdiction or the decision on the merits of the application will not be authorized. When the Service is in receipt of any information that would indicate that an application for naturalization should not have been granted on the merits, the Service may institute proceedings to reopen the application before admission to citizenship, or to revoke the naturalization of a person who has been admitted to citizenship, in accordance with section 340 of the Act and § 335.5 of this chapter.

(a) Application. Any person who is a lawful permanent resident over 18 years of age may file an application for a declaration of intention to become a citizen of the United States while present in the United States. Such application, with the requisite fee, shall be filed on the form specified by USCIS, in accordance with the form instructions.

(b) Approval. If approved, USCIS will retain the application in the file and advise the applicant of the action taken.

(c) Denial. If an application is denied, the applicant shall be notified in writing of the reasons for denial. No appeal shall lie from this decision.
