Special Naturalization Provisions
Provisions covering special classes of persons whom may be naturalized even though they do not meet all the general requirements for naturalization. Such special provisions allow: 1) wives or husbands of U.S. citizens to file for naturalization after three years of lawful permanent residence instead of the prescribed five years; 2) a surviving spouse of a U.S. citizen who served in the armed forces to file his or her naturalization application in any district instead of where he/she resides; and 3) children of U.S. citizen parents to be naturalized without meeting certain requirements or taking the oath, if too young to understand the meaning. Other classes of persons who may qualify for special consideration are former U.S. citizens, servicemen, seamen, and employees of organizations promoting U.S. interests abroad.
