Applicants must apply for naturalization with the United States Citizenship and Immigration Services and pay requisite fees. They must demonstrate good moral character, evidenced by a lack of a criminal history, and must pass a test on United States history and civics. The questions are publicly available on the web and require the applicant to answer ten out of one hundred possible questions. Most applicants must also have a working knowledge of the English language, demonstrated by testing their basic ability in reading and writing, rather than fluency. Long-term permanent residents are exempt from the language test. For example, a person who is over age fifty with twenty years of residency or over fifty-five with fifteen years of residency can opt to take the civics test in their original language. Persons over age sixty-five with twenty years residency may be given a shorter list of questions and those with physical or mental disadvantages are exempt from either the language or civics examinations. Granting of nationality is contingent upon taking an Oath of Allegiance; however since 2000 an exception has been made for people with diminished physical or mental capacity.
