<P> Under current law , all male US citizens between 18 -- 25 years of age are required to register within 30 days of their 18th birthday . In addition , non-US citizen men between the ages of 18 and 25 ( inclusive ) living in the United States must register . This includes permanent residents , refugees , asylum seekers , and undocumented immigrants . Foreign men lawfully present in the United States who are non-immigrants , such as international students , visitors , and diplomats , are not required to register . Aliens on lawful non-immigrant status are not required to register so long as they remain in that status . If an alien 's non-immigrant status lapses while he is in the United States , he will be required to register . Failure to register as required is grounds for denying a petition for US citizenship . Currently , citizens who are 17 and 3 months old can pre-register so when they turn 18 their information will automatically be added into the system . </P>
