Male U.S. citizens and male immigrant non-citizens between the ages of 18 and 25 are required by law to have registered within 30 days of their 18th birthdays
THE LAW
Selective Service law as written now refers specifically to "male persons" in stating who must register to be drafted. For women to be required to register with Selective Service, Congress would have to amend the law.
THE SUPREME COURT
The constitutionality of excluding women was tested in the courts. In 1981, Rostker v. Goldberg, held that registering only men did not violate the due process clause of the Constitution.
With the near full inclusion of women in all military fields, it is now time to require them to sign up for Selective Service and comply with the same requirements that are directed at males.
