This database reports naturalization petitions, persons naturalized (civilian and military), and petitions denied for Fiscal Years. (Fiscal Years prior to 1976 refer to July 1-June 30; Fiscal Years after 1975 refer to Oct. 1-Sept. 30. Fiscal Year 1976 contained 15 months, from July 1, 1975-Sept. 30, 1976.) 1907 includes naturalizations from September 27, 1906 to June 30, 1907. Naturalization is the process by which U.S. citizenship is conferred upon foreign citizens or nationals after fulfilling the requirements established by Congress in the Immigration and Nationality Act (INA).
The three-year moving average reflects of the ratio of petitions denied to those approved and is included since many petitions are not adjudicated in the year in which they are filed. Each petition relates to one person. Petitions filed in one year may not be adjudicated during the same year. Data on military naturalizations prior to 1918 are not available. Special provisions for military naturalizations expired or suspended in 1925 and 1935.

APA
Format or style, from the American Psychological Association, is commonly used for footnotes in behavioral and social science publications. APA citation is an author-year-system. It is one of the most common styles used and taught at colleges and high schools. See here for more details, including APA formatting for bibliographies.Chicago
Format or style (also known as Turabian), created by the University of Chicago, is commonly used for footnotes in history, business, and fine arts and occasionally in the humanities, sciences, and social sciences. The Chicago style has two systems of citation. The author-date system (most common in social sciences and sciences) cites sources parenthetically in the text. The notes and bibliography system (most common in humanities) cites sources in numbered footnotes or endnotes which correspond to a superscript number in the text. See here for more details, including Chicago formatting for bibliographies.MLA
Modern Language Association (MLA) format or style is most commonly used for footnotes in the language arts, cultural studies, liberal arts, and humanities. MLA uses short parenthetical citations within the text that are linked to an alphabetical list of work cited at the end of the document. MLA commonly cites using this format: author's last name, first name, title, publication, edition or chapter, and year. See here for more details, including MLA formatting for bibliographies.AMA
American Medical Association (AMA) format or style is most commonly used for footnotes in medicine, biomedical research, nursing, dentistry, and other life sciences. AMA uses numerical superscript for citing sources in-text and refers to a list at the end of the work. These references appear in sequential order of when the sources were cited, instead of alphabetical order. See here for more details, including AMA formatting for bibliographies.
