To become a naturalized United States citizen, one must be at least eighteen years of age at the time of filing, a legal permanent resident of the United States, and have had a status of a legal permanent resident in the United States for five years less 90 days before they apply (this requirement is reduced to three years less 90 days if they (a) acquired legal permanent resident status, and (b) have been married to and living with a citizen for the past three years.) They must have been physically present for at least 30 months of 60 months prior to the date of filing their application. Also during those 60 months if the legal permanent resident was outside of the U.S. for a continuous period of 6 months or more they are disqualified from naturalizing (certain exceptions apply for those continuous periods of six months to 1 year). They must be a “person of good moral character” and must pass a test on United States history and government. Most applicants must also have a working knowledge of the English language (there are exceptions for long-resident older applicants and those with mental or physical disabilities), although this requirement is not intended to be an onerous one, since the test requires that they read and write simple sentences in English, such as “The United States is a democracy.” However, some applicants fail the language and civics tests, and others are deterred from applying for naturalization by virtue of the test requirement.
