According to the Selective Service System, certain groups are exempt from service in peacetime draft, including ministers, certain elected officials, and veterans. Disabled persons, those who are incarcerated, and men who are not between the ages of 18 and 26 are also exempt from registering for the draft. Women are currently not required to register for the draft, but if Congress changes the law, they may be required to do so. Conscientious objectors are required to register, but they may qualify for alternative service. In the event of a military draft, the following instances are eligible for postponement: serious illness or death in the immediate family, emergency beyond the registrants control, and certain types of study. The following instances are eligible for deferments: high school students, undergraduate college students, graduate students, and certain types of study.
It is important to note that just because someone is registered for the draft does not mean they will automatically have to serve in the military if a draft is reinstated. If someone has a physical or mental condition that keeps them from serving, that will be decided after they are drafted. The same goes for people who are dual nationals.
In summary, being exempt from the draft depends on various factors such as age, gender, occupation, and health condition. If someone is registered for the draft, it does not necessarily mean they will be drafted, and they may be able to qualify for postponements or deferments.
