2. Failure to register is a violation of the Military Selective Service Act. Conviction for such a violation may result in imprisonment for up to five years and/or a fine of not more than $250,000. Once you reach age 26, it's too late to register. Even though you may not be prosecuted, you may be denied student financial assistance, federal job training, and most federal employment unless you can provide convincing evidence to the agency providing the benefit you are seeking, that your failure to register was not knowing and willful.
