While a non-citizen member of the U.S. armed forces must meet the general requirements and qualifications to become a citizen of the United States like good moral character, some of the other requirements are either reduced or completely waived. For example, qualifying service members and certain veterans need not demonstrate residence or physical presence in the United States, and can forego paying an application fee or biometrics fee to apply for naturalization. Furthermore, service members who serve during specific periods of hostilities may not have to be legal permanent residents.
