The requirements for foreign Commonwealth nationals applying for British citizenship, who are also serving members of the armed forces, are the same as for any other foreign national applying for citizenship. They must make a successful application for naturalisation under sections 6(1) or 6(2) of the British Nationality Act 1981. The statutory requirements for naturalisation are set out in that Act and are summarised in the guide for applicants that accompanies application forms. Policy and procedures for handling applications is available for viewing on the IND website: http://www.ind.homeoffice.gov.uk
